Superfund Lab


The Environmental Protection Agency serves a vital role in the preservation of our planet. On December 2, 1972, President Nixon combined several departments that measured, monitored, and researched environmental impact to form the EPA and begin working on the growing national concern about pollution.  Their quest is to work towards a cleaner and healthier environment in the United States. One of the ways that the EPA accomplishes this goal is through Superfund sites.  Superfund sites are sights that were once hazardous waste disposal sites. It is one of the EPA’s missions to clean up these areas and establish viable environments in them and hold the companies responsible for the pollution.

914th Airlift Wing-AFRC

One of these Superfund sites is located in Niagara Falls, New York.  Naturally, what first comes to mind when we think about Niagara Falls is the majestic waterfall that attracts so many tourists each year.  Only a few miles away sits the 914th Airlift Wing-AFRC. This military facility was opened in 1942 has trained reserve officers and airmen for over seventy years.  Unfortunately, defense missions that were used for training purposes left behind hazardous material that contaminated the ground water in several areas.

The New York State Department of Environmental Conservation assumed responsibility for the cleanup of the 914th Airlift Wing-AFRC areas that suffered the highest damage. The Former Fire Training Pit, the Underground Tank, the Landfill, and the Former Hazardous Waste Drum Storage Yard, were areas of greatest concern. These areas showed high levels of benzene, trichloroethene, and vinyl chloride and needed to have cleanup to prevent further damage.


In 1996 The Former Fire Training Pit an Interim Corrective Measure took place for six months using soil heating and soil vapor extraction to reduce the concentrations of volatile chemicals in the soil. The storage drum facility under went product recovery and is still undergoing biodegradation testing. Fortunately, the EPA was able to determine that the contamination has been restricted to the military base and because of limited access to the area had not spread outside the fences of the base.

Minot Landfill

Another Superfund site resides in North Dakota, not far from the Canadian border. Smack in the middle of Ward County North Dakota is the Minot Landfill. The landfill covers 26 acres of land and was an operational landfill from 1961 to 1971. The landfill was used to dispose of municipal and industrial waste including drums of oil, battery casings, lime sludge and calcium carbide. When the landfill closed in 1971 it was buried under three feet of clay and seeded. The land was used for recreation and traffic. Unfortunately, reports of foul odors and gas bubbles began to surface by 1985 causing the EPA to take notice of the site. Testing by the EPA and the North Dakota Department of Health revealed that the soil, groundwater and surface water were contaminated with harmful chemicals such as benzene, toluene, halogenated aliphatics not to mention arsenic and barium. In 1989 the EPA added the site to the National Priorities List.



In order to clean up this site, the EPA collaborated with local city and state efforts. Drains were installed to collect the water contaminated by traveling through the waste underground. Strict regulations were also put in place to regulate how the surrounding land was used. The EPA put the site on a five year review cycle and asked for public opinion during each one of these reviews.

While there are no current plans to reuse the site, grass grows and is harvested twice a year for hay. The EPA has determined that the cleanup efforts are successful and an ongoing process, but continues to review the site and its progression every five years.


Dixie Oil Processors

A third Superfund site can be found in the southeast corner of Texas. In Harris County, just twenty short miles south of Huston is a place called Dixie Oil Processers. This site occupies over 26 acres of land and is split into two regions, a North DOP and South DOP. The north claims 19 acres of this site and the south has just over seven acres. DOP North was open from 1969 to 1978. Insides its borders were six pits used for storage and treatment of wastewater containing copper (prior to the copper being recovered and discharged). These pits were no longer in use by 1977. With DOP North discontinuing operations; DOP south opened for business in 1978 and closed in 1986. DOP South was used for hydrocarbon washing to produce chemicals such as fuel oil and other petroleum products.

In 1984 they removed 6, 000 cubic yards of contaminated soils, but by the time DOP South closed it left behind more than 100,000 cubic yards of contaminated soil. What contaminates were left behind in the soil? Ethlybenzene, hexachlorobenzen, methylene chloride, and tolene just to name a few! In 1988 the EPA issued a Record of Decision on the site. The ROD stated that there would be limited action, which included fluids stabilization and site cover.

The DOP site undergoes a review every five years and in August of 2006 was removed from the National Priorities List. The containment remedy and soil cover over the site greatly reduce the human health risk. While there are plans to use the site for other purpose, those plans do not include residential use.

IKMHSSS

For those of use that live in northern Arizona, there are superfund sites in our back yards. Once such site in located in the Dewey-Humboldt area. The Iron King Mine Humboldt Smelter Superfund Site (IKMHSSS) lies right outside of Dewey-Humboldt. In 2008 the EPA decided to perform studies on the mine tailings to determine photostabilization ability. The vegetation used in these studies were picked from a selection of vegetation that was (and is) natural to the surrounding area. These included catclaw and mesquite trees, quailbush and mountain mahogany bush, Arizona fescue grass, deer grass and buffalo grass.

The study required that different levels of compost be mixed in with the mine tailings. Because the mine tailings created acidic soil, one the compost was mixed in (the compost being neutral to alkaline) the pH of the soil increased.

After 60 days of growth in a 10% compost mixture, the vegetation used showed varying rates of dry shoot weight. The catclaw weighed about .5 grams, the mesquite at 1 gram, quailbush at 1.5 grams, mountain mahogany at .75 grams, Arizona fescue grass at .25 grams and buffalo grass at 4 grams. The buffalo grass and quailbush both appeared to thrive with only the 10% compost mixture, while the rest of the vegetation showed minimal amounts of growth.

Bacterial counts were also measured at IKMHSSS. In the control area (with no compost added) on the first day of the study neutrophlic hetrotrophic bacteria counted at 103 CFU. On day 60 of the study the area mixed with 15% compost showed a neutrophlic hetrotrophic bacteria level of 108 CFU.  This was the highest count of any level of compost mixture at any point during the study.

Superfund sites hold important value to our country. These once abandoned toxic sites damage our environment and the surrounding neighborhoods. It is the EPA’s mission to reclaim these areas and turn them into productive pieces of land. Once at a time they are succeeding, but it is evident that community support and participation is a vital part of this process. The EPA cannot do it alone, each one of us holds a responsibility to create happy, healthy environments for the generations to come.

Where Do We Get Energy?

Mankind started using energy provided by fire, then animal muscle power, then water and wind. By the dawn of the 1800’s coal was being used as reliable energy source. In the twentieth century oil became one of the main sources of energy. We have drilled to the ends of the earth, literally, for this liquid gold that much of the developed world has learned to rely on. Americans alone go through around 60 barrels of oil per person every year! These fossil fuels make up 88% of our planets commercial energy needs. This need is not only damaging the planet, but incurs astronomical costs to find, keep and develop these precious fuel sources.



How Do We Measure Energy?

For people who need more than just the explanation that we need energy for electricity and just about everything else we do, there are specific measurements for energy. Work is actually defined as the application of force over distance.  Work is measured in joules. Energy is the capacity to do work, and power is the rate of energy flow or the rate of work done.  Think of it like this: Pushing a large boulder requires work, with each step you increase the amount of joules and create energy. How fast you push that boulder determines how much power you have.

How do We Use Energy?

Developed countries such as the United States depend on fossil fuels. Without them our day to day life would come to a screeching halt. 37% of the fossil fuels we use comes from oil, while 24% comes from natural gas and 23% comes from coal. Although the United States only has less than five percent of the world’s population within its borders, they consume one fifth of all of the fossil fuels consumed.  We use these fossil fuels to drive our cars, heat our homes, and make materials for our use such as plastics, metals and fertilizers.


Despite the fact that the United States is beginning to use solar, wind and geothermal power, it still only makes up one percent of the energy supply. Nuclear power provides us with 20% of all of our electricity.
 
Unlike the United States, some developed countries have opted to use more renewable sources of energy. Sweden, Denmark, and Finland have a higher standard of living, but use a fraction of the energy that the United States does.

Coal as a Fossil Fuel

Coal is a relatively abundant resource and if used efficiently could last us thousands of years. Unfortunately, the downside of the extraction of the coal far outweighs the positive energy that it gives us. Coal mining is notoriously dangers, killing countless miners, either immediately as a result of cave ins, or slowly through lung cancer and other deterioration. 

More damaging to the planet than underground mining for coal is the process of Mountain Top removal. The damage that mountain top removal k process inflicts in irreversible and not only damages the mountain, but the valleys below where the tailings are deposited.

Coal (once burned to create energy) releases dangerous toxins into the atmosphere. Coal releases carbon dioxide, creates sulfur dioxide. While it is possible to create gas and liquid fuels out of coal, the process is dirty and much more expensive than just burning straight coal for energy resources. 


There is an effort to develop cleaner coal plants. Over time these integrated gasification combined cycle plants will pay for themselves as well as help preserve our atmosphere. There is a IGCC plant in Florida that has been successful and operational for more than ten years. The IGCC plants do not burn the coal, but convert this solid to a gas and then burns the gas in a turbine.

Oil As A Fossil Fuel

Our oil use peaked during the 1970’s and then again in 2005-2012. Today it is believed that only half of the world’s oil is recoverable, the rest is to embedded in rock formations or too deep underground to be extracted to meet our ever increasing demand for this resource. There is fierce competition for oil around the globe as countries such as India and China continue to increase their energy needs.   
  

Here in the United States we have used over half of our recoverable oil resourced. If we stopped importing oil all together, the remaining domestic supply would be depleted in just four short years.  Our eternal quest for this liquid gold continues to be dangerous to extract. Not just for the men and women working on the rigs, but the surround ecosystems. In 2010 when the Deepwater Horizon exploded it killed eleven people, wounded even more and killed more wildlife than can be counted. The cleanup effort was grueling and costly.

There are other methods of obtaining oil. Tar sands are made up of bitumen that can (through a costly and vigorous process) be extracted to make many of the products that we use today. Large deposits of tar sands can be found in Canada and Venezuela. In 2000 Canada surpassed Saudi Arabia as the largest supplier of oil to the United States.  While the tar sands provide an answer to the potential oil shortage, it comes with a high environmental price. The process of extracting the bitumen creates toxic sludge and releases thousands of tons of greenhouse gasses into the air.  The extraction also requires and contaminates countless gallons of water.


Oil Shale provides us with yet another form of oil. Oil shale is a fine grained rock rick in kerogan that can be heated, liquefied and pumped out like oil. There are large deposits of oil shale in Utah, Oregon, and Colorado. Unfortunately, the extraction process creates large amounts of carbon dioxide and requires copious amounts of water (and if you live in the Western United States, you know that water is a precious commodity).      

Natural Gas as a Fossil Fuel

Of all of the fossil fuels used in our world today, natural gas is by far the cleanest of them. As our world has begun to express concern about the growing pollution problem, the demand for natural gas has increased. Russia claims close to a quarter of the planets natural gas reserves and the Middle East has more than forty percent of the planets natural gas. Despite this the United States still has large deposits of natural gas and functional pipelines to transfer this gas across the country.  However, international transport (particularly overseas) is extremely dangerous. Each boat transporting the liquefied gas (LNG ships) has the same explosive power as an atomic bomb, making ports hesitant to open to this cargo.


Despite the fact that natural gas use reduces the risks of global warming, it still has harmful impacts on the environment. When natural rock beds are cracked to extract the pockets of methane gas, causing chemicals can seep into ground water and contaminating the supply.               

Conserving Our Energy

One of our biggest issues with energy is that we waste most of what we use. The less we use and waste the longer it will last. While that seems like a simple statement for a complex problem, most of us have already set ourselves on the energy saving path whether we know it or not. Our cars have better fuel efficiency that ever before. Naturally, we don’t all go to the car dealership and pick out a car with higher gas mileage because we are thinking about our energy use or reducing our footprint. Most of us pick that car because we cannot afford the rising cost of gasoline.


The same can be said for our “Energy Star” appliances. Manufacturers put the sticker on the front of the new washing machine that you are looking at that says instead of costing $46 a year to run it will only cost you $24 in electricity each year. Not because electricity is getting any cheaper but because these everyday household items are becoming more energy efficient and decreasing the amount of wasted energy.


Today the government offers tax breaks to households that use double insulated windows or install other “green” features in the home. Energy companies have also begun consolidating and producing two forms of energy out of one plant, reducing the impact on the environment. We are well on our way to energy conservation, but the path is long and we must remember to teach the younger generations to continue the work that we have started.        


Chapter 8

What is Health? What is Disease?

What is health? When many are asked this question their response may be that health is the absence of illness. According to the World Health Organization (WHO) health is not only the absence of illness but the state of complete physical, mental and social well being. When you think about health on those terms, none of us are completely healthy, but we spend most of our lives trying to get there.


Disease on the other hand, is what we spend most of our lives trying to avoid. Disease is a abnormal change in our bodies that impairs our physical or physiological state. Many things contribute to our illnesses, not the least of these is our diet, nutrition infectious agents and toxic substances. Also on that list is stress and trauma.  The WHO blames more than twenty percent of global disease on environmental factors.

A Changing Disease Burden

Disease does not just affect our health and well being, it affects our global economy. When we are sick we cannot work, we cannot feed our families, and children cannot get an education. In an effort to try to capture this impact that disease has on our global economy not just on mortality rates, health agencies invent DALYS (disability-adjusted life years). This calculates the years lost because of disease. For example if a child becomes disabled because of a car accident, the DALYS lost is higher than that of a 65 year old who is incapacitated because of a heart attack.

The world is beginning to see an increase in chronic conditions. Fifty years ago cardiovascular disease and cancer was only seen among the wealthy, now it can be seen in the poor neighborhoods around the world. The WHO estimates that heart disease will replace pneumonia on the leading cause of global disease burden by 2020! Chronic conditions that pose a disease burden are not limited to physical illness but psychological as well.  In 2020 depression will be the second leading cause of global disease burden worldwide. Lung disease is also expected to climb the charts by 2020 replacing other illness like diarrhea.

Emergent and Infectious Disease

Communicable diseases still pose a huge mortality risk around the world. They are responsible for one third of disease related mortality. Most of these communicable diseases could be eradicated if clean water, better sanitation processes, and vaccinations were applied in developing countries. Diseases can cause pandemics that spread like wildfire and kill hundreds of thousands of people like the Great Influenza Pandemic of 1918 and what many feared H1N1 could have caused in 2009.

Despite our advances in medicine, malaria still remains one of larges infectious diseases. The mosquitoes that carry this deadly virus have expanded their territory and have begun affecting more countries than ever before. While treatment and prevention of malaria would be as simple as a pill and a bed net, many countries that suffer from this deadly disease cannot afford event that.


Emergent diseases are diseases that have not ever been seen or have not been seen in at least twenty years. H1N1 is a good example of an emergent disease. Ebola and Marburg fevers have also made a comeback as emergent disease in Africa in the last twenty years. Cholera, and dengue fever have also appeared back on the map. The more the human population moves into remote and previously unsettled land, the more risk we have of new disease that humans have never encountered before.

Perhaps the most widely known and the most deadly of these emergent diseases is HIV/AIDS. This disease has made a huge impact on the globe in the last thirty years. Three million people die every year from HIV/AIDS and 33 million are infected around the globe. In developing countries many children contract HIV/AIDS through childbirth and/or breastfeeding. This could be prevented with a cheap procedure completed during childbirth.

Conservation Medicine

Humans are not the only species greatly impacted by global disease. Animals contract and spread disease as much if not more so than humans. This is called ecological disease. Just as humans pass illness and disease to one another, so do animals. In 1949 oysters in the Chesapeake bay suffered from a MSX parasite that killed millions of tons of oysters. Ebola fever killed around 5,000 gorillas in the Congo and botulism spreads like wildfire through migrating birds.


The more we disrupt ecosystems the more we put our globe a risk for widespread illness and disease. We introduce foreign animals into different ecosystems and they bring with them parasites and bacteria that the local wildlife has no resistance to. In today’s modern world we can transport disease and illness around the world in just a few days.  Conservation medicine is our attempt to learn more about our impact and how these changes to our environment are impacting our planet.

Antibiotic Resistance

Many strains of illness and infection have become immune to our antibiotic treatments. The more frequently that antibiotics are prescribed (especially if they are not necessary) and the more people who do not complete their prescribed antibiotic regime the faster these illness will become resistant to antibiotics.


When pests and pathogens are only exposed to our control measures in a mild form, they are given the opportunity to build up resistance.

Global Health Care

Health care is a huge concern around the world. The poor are the most afflicted by disease and illness and these are the people who cannot afford health care or a better living environment.  The WHO stated that 90 percent of the need for healthcare is in developing countries, but less than 10 percent of the healthcare dollars are spent there.


It is clear that our world needs to take a serious look at health care and ask themselves where each one of us holds responsibility. Do those of us in developed countries really deserve health care and a healthy living environment more than those in developing countries? Can each of us afford the minimal cost to help a family in a developing country provide health care and clean water for their family? Is it worth it to us?

Toxins and their Affect

Toxics and toxins are poisonous. They include chemicals, radiation, UV light, and electromagnetic forces.  Toxic material disrupt metabolic function causing damage and even killing living organisms. Environmental toxicology studies the effects of toxins in organisms and ecosystems.


A toxin that we can all claim familiarly with are allergens. Allergens flip on the switch in our immune system. Sometimes just the presence of the allergen triggers our immune system to start creating antibodies to fight it off. Other allergens must first bind to foreign material to cause the immune system to respond with antibodies.


Neurotoxins are metabolic poisons that attack our nerve cells. These attack our nervous system which is vital to our body activities and the results can be devastating. Lead and mercury can kill nerve cells and cause permanent neurological damage. Anesthetics disrupt the nerve membranes generally temporarily, we know these neurotoxins as what numbs our body when we go in for surgery.

Mutagens alter our DNA which can lead to birth defects and tumor growth. Teratogens are factors that cause issues during embryonic growth and development. The most common teratogen (known to us) is alcohol. Alcohol use during pregnancy leads to fetal alcohol syndrome. This teratogen is completely avoidable and preventable.  Carcinogens are the toxins that cause cancer. Cancer is the second leading cause of death in the United States. We are exposed to carcinogens at a surprising level at all stages of our life, beginning in the fetal stages.

Toxin Mobility

Toxin mobility depends on the toxins solubility. If the toxin is water soluble then it has a wider range of mobility since water moves more freely and rapidly through our environment. Once introduced to our body the toxin has complete access to our cells. If the toxin is oil soluble, it has a more difficult time spreading through the environment and generally needs a carrier, however once it enters the human body it absorbs into the tissue and fatty cells of the body where they can survive for years.


Exposure

We are exposed to toxin in many ways. Some are airborne and very easy to contract. This airborne toxins usually cause the most problems for us and are sometimes hard to avoid since air is everywhere and no matter where we are we need it. We can also absorb toxins through water and food, but if we are aware that a certain food or water source is contaminated, we can avoid it (unlike air, we cannot hold our breath indefinitely). Skin contact is another way that we are exposed to and absorb toxins. Imagine a factory worker that touches a small amount of lead every day, eventually that skin contact will cause problems. 






Because children have a less developed immune system it is much easier for them to be affected by absorbed toxins. Their bodies are much for sensitive to damage caused by toxins which can cause long term consequences.

Bioaccumulation and Biomagnifications

Bioaccumulation is the cells ability to absorb and store nutrients and essential minerals. This same ability can also enable the cell to absorb and store harmful material. Biomagnifications is when the toxic burden of a group of organisms is accumulated by a predator. For example, if algae absorbs a heavy metal or another toxin, a single fish can consume a large amount of this algae causing a high level of the toxin in the fish. Then a larger predator consumes a large amount of the fish. The larger predator will now begin to suffer adversely because of the toxin.
  
Persistence

Most toxins degrade when exposed to sun, air, and water. This makes these toxins inactive. Unfortunately, some toxins are persistent and do not degrade when exposed to the elements. One of these toxins is Mercury. Mercury is a byproduct of the coal burning. Mercury is released into the air and concentrates in high levels in fish.  Most states have issued warnings about mercury levels in their local fish and recommend that pregnant women and children do not consume fish.

                                                                                                                       

Chapter 15

Driving Policy

Policies are rules or decisions that determine how we deal with problems. Policies can be (and are) made on every level. Each of us makes policies for our lives, cities make policies, states make policies and the federal government makes policies. Our governments establish policies to protect our rights, our health, and our money. Our national government also makes policies to protect our environment.

Because we are fortunate enough to live in a democratic nation, many different things drive policy. Public citizenship is an important driver for establishing and or changing policies. Some of the biggest policies established to protect our environment (such as the Clean Water Act) were initiated by individuals in communities. These same citizen initiated policies have had global reach. The Chinese government has had to establish and modify many policies in response to citizen actions in the form of environmental protests.

Naturally, groups with political interest, industrial interest, and labor unions also impact policy and policy change. Wealthy groups and other powerful individuals also exercise influence over policy.

Policy Cycle

To create policy there is a process, a continuing cycle for the life of the policy (imagine in your head the school house rock video “I’m just a bill here on Capitol Hill” and you come close to the process of a policy). 



To begin the process a problem must first be identified. Then an agenda or purpose of the policy must be created and proposals decided on. Of course, support for the policy is imperative. This can be accomplished through campaigns, lobbing, and public education. The next step is to enact the law or rule and then to decide on how it will be enforced. After a period of time the policy’s results will be evaluated and changes may be suggested. Then the cycle begins all over again.



NEPA

The National Environmental Policy Act (or NEPA) was signed into law by President Nixon in 1970. This act established a Council on Environmental Quality as well as directs agencies to take under consideration the impact their decision making will have on the environment. Finally, it required that Environmental Impact Statements be published for each federal project that could have an important impact on environmental quality.


The purpose of the EIS was so that any major federal project would have to document and make public any risk or change it could pose to the environment, allowing citizens the opportunity to oppose or support the project.  Each EIS must include three parts: a purpose and need for the project; a alternative to the purposed action; and a statement of positive or negative impact on the environment.


The Clean Air Act

The Clean Air Act was written into legislation in 1970. The CAA was established because of serious concern about pollution since the industrial revolution. The burning of coal and other products caused high levels of sulfuric acid, and airborne metals such as mercury in the air which has lead to serious health risks. The intense impact of this pollution was realized when in 1953 London was engulfed in stagnate air full of these pollutions. Thousands died as a result of asphyxiation and thousands more because of respiratory issues resulting from the pollution. Since the CAA was enacted, these pollutants have declined dramatically.


The Clean Water Act

The Clean Water Act was written into law in 1972 and tries to keep surface water safe for swimming and fishing. This Act aimed and first finding the sources of the water pollution such as end pipe discharge from factories and other industries. By the end of the 1980’s the water pollution from these sites was nearly under control.


The Endangered Species Act

The Endangered Species Act became part of our law in 1973. It provides a list to the government of species that are at vulnerable, threatened and endangered. The ESA provides rules and enforcement for the protection of habitats (which can cause issues when developers want to built housing developments in the middle of these habitats).

In 2010 there were 1,969 species on the worlds endangered species list, 753 of them were plants.


The Superfund Act

In 1980, the federal government passed the Superfund Act. The Superfund Act aimed at repairing abandoned toxic land. The EPA was tasked with finding the company responsible for the pollution and holding them financially responsible for the cleanup. The EPA also supervised the clean up and determined when the site was “healthy” enough for use and what type of use. In 1995, Congress changed the method of funding to the Superfund Act and now the financial burden of the cleanup falls largely on the taxpayers.



Making Policies

The making and enforcement of laws involves all three layers of government. The legislative branch of our government is responsible for writing policies, laws, and rules. Each member of congress has the opportunity to vote in favor and against each policy, law or rule brought before them. Ideally they vote in a manner that would benefit their constituents.


The judicial branch interprets the laws passed by the legislative branch. It is their job to decide if the law has been broken, what it means, and if it is constitutional. The judicial hold responsibility over criminal and civil law. Sometimes when a law is broken it can be criminal and civil. When the Deepwater Horizon exploded causing the Gulf Oil Spill in 2010, the company was held criminally responsible by the government and civilly responsible to the people that were financially impacted.

The executive branch hold the responsibility of enforcing the laws enacted by the legislative branch, and interpreted by the judicial branch. The executive branch is made up of federal agencies (as well as state and local boards). The executive branch can set rules, settle disputes and investigate misconduct. Specifically the Environmental Protection Agency has been tasked with monitoring our nation’s environment and its use and abuse. These agencies are headed by someone who is appointed by the president. The executive branch departments that hold the most significant environmental impact are the EPA, the Department of the Interior (home of the US Fish and Wildlife Service) and the Department of Agriculture (home to the US Forest Service). These departments work together to protect our national parks, our lands, and our ecosystems.

International Agreements

In the last several decades, countries have become more aware that our impact on the environment does not hold to man-made borders. Many problems are international and spread around the globe. It was with this thought in mind that countries began collaborating with each other and agreeing to treaties that protect our planet as a whole. Countries gather together at global conventions and plan best efforts to approach global concerns.

In 1973, the Convention on International Trade in Endangered Species agreed and declared that wild flora and fauna are valuable and irreplaceable. Because endangered species are threatened by human activities CITES created a list of endangered species that are affected by trade and restricted and established rules unauthorized or illegal trade from one country to another.

The Montreal Protocol was agreed on in 1987 and protects the stratospheric ozone. The treaty committed agreeing parties to phase out the manufacture of several chemicals that bread down ozone.  The Montreal Protocol is responsible for the phasing out of CFCs. When searching for an example of a highly effective international agreement, the Montreal Protocol serves as that example.

The Basel Convention in 1992 restricts the trade or shipment of hazardous waste to other countries. Before one country can transfer hazardous waste or chemicals to another, the receiving country must consent in writing for the transfer.

In 1994 the UN Framework Convention on Climate Change directed governments to share data on changing climate. This convention enables international plans for reducing and controlling greenhouse gases.

Enforcement

International enforcement is difficult because countries are hesitant to send foreign police into free state countries to enforce laws (accept in the instances of genocide). Despite that form of international enforcement, most countries desire to maintain national pride and to represent their countries with pride. Because of that, international treaties that are agreed upon are followed to the best of the country’s ability.


When treaties are decided upon, the signatories do their best to accommodate each country entering the agreement. Often treaties use words like “urge” instead of “shall” and are discussed until agreements are reached. As time goes on and countries develop, some treaties and agreements require modification. Agreements that do not require commitments, but instead meaningful actions are generally more widely accepted by the global communities.

What Can I do?

Of course policies, laws and rules established at the international, national, state, city and neighborhood levels are important and lay the foundation for environmental protection. However, the process begins and ends with the individual. Educators inform of the importance of environmental protection, scientist measure and validate methods of greener energy, artist capture our planet as it now and was then, and writers formulate opinions in ways that can be created into law. Each one of these people plays a role in the bigger picture. In our own homes we can make the choices to recycle, by greener cars, and equip our homes with energy efficient appliances and windows.
The most important thing I have learned this semester is that what one person does can matter. I lived with the misconception that one person could not make a difference and so it didn’t matter what just one of us did. I was wrong. What I do not only impacts my footprint, but the lessons my children learn and then teach their children will continue to make an impact on our planet. All it takes is one extra minute from me each day, enough to sort the trash.  Seems simple enough.
