Do people know what happens to things that they throw away? They think it gone for good, but scientists worry that if methane increases in the atmosphere, it could cause more warming than carbon dioxide when they burn the fossil fuels. It is important to know because of the methane from landfills because it is estimated that it causes between thirty and seventy million tons of emissions every year (Reay, n.d.). It is necessary to understand the sources and advantages, and disadvantages, of methane because it is dangerous because it can affect the environment.
Consistent with “Overview of Greenhouse Gases”, methane is a gas that has come from coal, natural gas, and oil, and it can come from the decay of landfills. Climate Change Division (2014) points out that landfills are massive amounts of garbage that are buried within the earth. Dave Reay concludes that

Reay (n.d.) reports, that “the time methanogens is generally much reduced and, where the soil dries out sufficiently, rice paddy soil can become a temporary sink for atmospheric methane,” or within the cows, and burning things and it can come from termites when they eat food because the bacteria inside of them. Speaking on additional sources of methane, Horita is quoted in “Methane on Earth” written by Tenenbaum (2005) that the methane can come from some bacteria on the earth that produced it. Kevin Schaefer is an NSIDC scientist who studies the carbon cycle. He asserts that there are some sources of methane in the arctic in deep of the earth or underwater. When the temperature changes then the methane will go out from the ice. He states that methane can also come from the remains of the frozen animals and the dead plants and from volcanoes and forest
The Lowry Landfill Superfund Site is located in Arapahoe County, Colorado, approximately 2 miles east of Aurora. It consists of approximately 507 acres of waste disposal area and is operated by Waste Management of Colorado, Inc. The land surrounding the site consists of native prairie grass and a wetland located along a local creek. Sections around the site are zoned for agricultural use including cattle grazing and non-irrigated wheat farms. 1 The area is home to numerous endangered species including the bald eagle and peregrine falcon. Due to the large amounts of wastes disposed on the site between 1965 and 1980, it became extremely contaminated with a variety of inorganic and organic contaminants. From 1984 to 1993, the EPA oversaw remedial investigation and feasibility studies that were performed by all responsible parties. Since its listing as a superfund site in 1984, multiple remedial actions have been performed in order to rehabilitate the site. These include clay barrier walls around the site, a groundwater collection system, a soil cover for the main landfill, as well as a landfill gas collection system. Groundwater that is collected on the site is treated at an onsite water treatment facility. In 2007, construction began on an onsite gas to energy plant that utilizes the methane produced by the landfill site. The electricity produced by the plant is enough to power 3000 households. 1 Today, use of land and groundwater on and near the site is still restricted by the state of Colorado.1

Humans are largely responsible for releasing these gases into the air. Gases like methane is used by farmers in practices such as livestock manure management. Carbon dioxide is released mostly from burning fossil fuels such as coal, oil and gas. Cutting up trees (deforestation) prevents the conversion of CO2 into Oxygen in our planet through a process called photosynthesis.
Take a moment and think about what you had for dinner last night; likely you consumed some type of meat - which when that animal was alive was probably a methane producer. CH4, or methane gas is the second most abundant greenhouse gas in the atmosphere. Methane comes from sources such as livestock, landfills, producing and transporting natural gas, and mining coal. Livestock only produces a fraction of the amount of methane produced every year. Drilling and the transportation of natural gas and use of natural gas and petroleum systems produce far more methane than livestock do. Livestock’s emissions of methane is not where change needs to occur; transportation and natural gas practices are what need
The emission of green house gasses due to human activity contributes the most in increasing global warming. Today, fossil fuels are used as a source of energy for transportation, electricity, industrial process and to increase human comfort in this era. Over the last decade humans have created mass amount of industries. These industries have been burning fossil fuels such as coal, which release carbon dioxide and carbon monoxide; carbon dioxide absorbs heat that raises the temperature of the earth. More than 80% of carbon dioxide comes from tr...
Waste incineration units produce a lot of carbon dioxide gas approximately around one third of the greenhouse gasses. It also impacts people’s health as they get exposed to the toxic emissions by breathing in the air or consuming contaminated food and water. Additionally, when the garbage gets burnt by the incinerators they end up as ashes which are then emitted from the chimneys, including the toxic materials and end up in specialist landfill sites for hazardous waste.
The emission of carbon dioxide has contributed to 80% to the heating of the earth atmosphere. Carbon dioxide is produced due the burning of fossil fuels such as natural gas, coal and oil. The burning of fossil fuel is very important in our society today, because it is used for cooking, used to produce electricity, for heating, for cooling and also for transportation. The industrialization has led to the use of fossil fuel for running machines and driving cars. The building of fossil fuel contributes towards 80-90% of the carbon dioxide we find in our atmosphere today. When the ecosystems are altered and vegetation is either burned or took out, the carbon stored in them is relinquished to the atmosphere as carbon dioxide (What causes global climate change, 2005). Methane is another gas being produced in the process which all have served to increase the greenhouse effect in our atmosphere. Methane is produced from the cultivation of rice, from the burning of coal and from cattle, it has increased by 145% due to human
For the previous 200 years, the industrial revolution’s discovery of fossil fuels reigned supreme. (Benefits of Recycling, History of Alternative Energy) Newly developed factories continued their steady streams of production and our society started becoming larger consumers. To meet the increasing demand, more product had to be made, and this resulted in more waste being emitted into the atmosphere. These gases built up until they caused the ozone layer to thicken to the point where it started trapping the h...
It is quite possible for the Earth to turn into a large landfill or garbage dump, however it is quite certain a preventative measure will be developed before that can happen. When looking at emission data, one can conclude that the Earth would have possibly succumbed to global warming as seen in the movie. In a study by Aljaradin & Persson (2016) the emission potential was tested on a solid waste landfill in Jordan. After 200 days, showed a methane content of over 45% and 15.7 l of Leachate was produced (Aljaradin & Persson, 2016:45). Methane is an important greenhouse gas, and one of the causes of global warming. Methane is 84 times more effective than CO2 at trapping heat in a shorter time (over the first 20 years). Leachate contributes greatly to the pollution of ground and surface water when improperly managed. Therefore it could be entirely possible that these landfills and dump sites caused the entire planet to succumb to the effects of global warming and uncontrollable
Food waste is huge issue these days. It is a huge amount of waste that ends up in landfills and can have lasting effects on the environment. One of major issues of food waste is the greenhouse gases that it produces. Methane gas is the main culprit when it comes to the gases being released. This can absorb infrared radiation and heat up the earth’s atmosphere and cause climate change. Another issue that food waste causes is, water loss due to use for production of fruits and vegetables.
The number of landfills in the United States is decreasing, but the amount and volume of waste being thrown into the new landfills is increasing (Russell 4). Because of this escalating amount of garbage, methane, which contributes to global warming, is an outcome of these landfills (Russell 7). As a result, our planet is suffering because of this epidemic. The garbage being put in the landfills could be recycled, but not enough businesses, schools and cities are promoting the “going green” trend.... ... middle of paper ...
