Methane gas is a greenhouse gas that is caused by both natural and human sources. It stays in the atmosphere for about seven to fifteen years. Methane is twenty times more effective in trapping heat then carbon dioxide. Methane gas is a contributor to global warming and continues to be a major problem for the environment. A positive thing about methane gas is it is a natural gas, so if used the right way it could be a great energy source. It is mostly distributed from human actions like factory farming or landfills. There are other ways methane is produced, but there are two leading factors in releasing the unfriendly gas, factory farming and landfills. These two topics will be presented in this paper because they both are at two different ends of the spectrum in helping with methane gas emissions.
A factory farm is defined by the Environmental Protection Agency as “new and existing operations which stable or confine and feed or maintain for a total of 45 days or more in any 12-month period than the number of animals specified.” In other words, it is where massive farms include thousands of animals in a confined area and harm animal and humans lives in order to receive a profit. A large factory farm includes 1,000 cattle, 2500 hogs or 125,000 chickens. They confine all of the different types of animals together to achieve the best outcome to sell in the market.
There are many issues in regards to factory farms, but the major one is the many environmental issues that come from it. Farms produce a lot of air, water, and land pollution. Methane gas is largely released from factory farms by the overwhelming amount of animal waste on each farm. It is estimated that an average factory farm produces 200 million pounds of animal waste a year and twenty percent of methane gas emissions. So what is happening with the methane gas? Since the waste is not being used, the massive amount of methane gas is released into the air to help effect global warming.
Factory farming is not the only place where methane gas is getting released, landfills are major contributors. Landfills also contribute to about twenty percent of the methane emissions. Landfills harm the environment by the gases that build up with all different items of trash. Even though landfills contribute to a lot of methane they are working to use this energy source. In 2009, the United States Environmental Protection Agencies counted 517 active landfill energy projects out of 3,091 active landfills and 10,000 old municipal landfills. Landfills still have a long way to come, but they have found a way to make use of the methane.
Both factory farming and landfills present issues on how to solve methane gas emissions? Factory farming is looked at by being solved by using alternative sources to get food. People want to put emphasis around little farms that are able to use livestock in not such a harmful way. Landfills have found a way to harvest methane and use it as an energy source, but it is not being used at every landfill. The EPA is not helping the issue of methane gas by letting people go over their restrictions of methane by paying a fee. On the other side, the Kyoto Protocol is an international agreement made between countries to reduce the amount of greenhouse gases they omit. They keep track of how many each country omits. Also companies are trying to use this gas in positive ways to help give energies to businesses. Both of these agencies and laws set in place for emissions of greenhouse gases will be talked about in greater detail. We have to wonder are our major organizations helping us or hurting us.
