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!

Burning fossil fuels is one thing that causes pollution. Once the greenhouse gases are emitted, some of these greenhouse gases end up in the atmosphere, where they trap a certain amount of originally solar energy (which would have otherwise escaped to space), and thus radiate this energy back to the Earth raising the planet’s average temperature. One way to deal with this issue is to develop alternatives to fossil fuels. Solar energy is the most abundant renewable energy resource on the planet. Some experts claim that the world’s annual energy demand can be met by harnessing solar radiation received by the Earth within just one hour (http://www.tropical-rainforest-animals.com/green-investment.html). Development of these renewable sources of energy should be the top priority (2008-2009, para 2), it is our earth and we need to take care of it, although human species has the ability, through rational thought, to conserve resources. Also, according to the EPA countries from around the world, including the United States, are working together to share technologies, experience, resources and talent to lower total greenhouse gas emissions and reduce the threat of global warming (http://www.eoearth.org/article/Global_warming).
Another major man-made cause of Global Warming is population. More people mean increased demand on earth's limited resources. So many people are pouring carbon dioxide into the atmosphere faster than plants and oceans can absorb it (2007, National Geographic). Another problem with the increasing population is transportation. More people mean more cars and more cars means more pollution. About 33% of U.S carbon dioxide emissions come from the burning of gasoline in internal-combustion engines of cars and light trucks like minivans, sport utility

vehicles, pick-up trucks, and jeeps (US Emissions Inventory 2006 page 8). Vehicles with poor gas mileage contribute the most to global warming. For example, according to the E.P.A's 2000 Fuel Economy Guide, a new Dodge Durango sports utility vehicle (with a 5.9 liter engine) that gets 12 miles per gallon in the city will emit an estimated 800 pounds of carbon dioxide over a distance of 500 city miles. In other words for each gallon of gas a vehicle consumes, 19.6 pounds of carbon dioxide are emitted into the air. (Marland, Gregg. Carbon Dioxide Information Analysis Center). A new Honda Insight that gets 61 miles to the gallon will only emit about 161 pounds of carbon dioxide over the same distance of 500 city miles. I myself own a Chevy Trailblazer and a mid size car, and I try and drive the smaller one as much as possible.
Also, many people have more than one car. The world’s population is struggling to come to terms with the issue of global warming and how it is becoming more than just a false belief. Changing the world can be so simple, just decreasing the amount you use your car could help. Walk or ride your bike for short distances, park and walk. If you...
