Global Warming

Environmental ethics is a big concern to life on earth. Global warming is a big part of the concern. Global warming is the increase in global temperatures brought about by the increased emission of greenhouse gases into the atmosphere (2009, Answers corporation). Scientists have determined that a number of human activities are contributing to the excessive amounts of greenhouse gases to the atmosphere.   This is a worldwide issue, and I believe more people need to step up and help.   I do not understand how anyone could say that they do not care about the earth!
“Scientist has spent decades trying to figure out what is causing global warming. They have looked at the natural cycle and events that are known to influence climate. But the amount of pattern and warming that has been measured can’t be explained by these factors alone” (1996-2009, National Geographic Society, para 1).   Almost 100% of the observed temperature increase over the last 50 years has been due to the increase in the atmosphere of greenhouse gas concentrations like water vapor, carbon dioxide, methane and ozone (Juerg Rohrer, para 1). Greenhouse gases are the gases that contribute to the greenhouse effect.   The largest contributing source of greenhouse gas is the burning of fossil fuels leading to the emission of carbon dioxide. Carbon dioxide is by far the most important past and current greenhouse gas, followed by methane and nitrous oxide ( 2008-2009, para 20).   Fossil fuels are fuels made of organic matter such as coal, or oil. When fossil fuels are burned they give off a green house gas called CO2. Also mining coal and oil allows methane to escape. It escapes when coal or oil is mined because methane is naturally in the ground ( para 3).   Man-made causes probably do the most damage.

There are many man-made causes. Pollution is one of the biggest man-made problems. Pollution comes in many shapes and sizes. Burning fossil fuels is one thing that causes pollution. Once...
