GLOBAL WARMING 1. Global warming is the increase of Earths average surface temperature due to greenhouse gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation, which trap heat that would otherwise escape from Earth. 2. Greenhouse gases keep heat close to the earth’s surface making it livable for humans and animals. However, global warming is happening largely due to an over-emittance of these gases and fossil fuels (natural oil, gasoline, coal). 3. With the start of industry in the 1700s, humans began emitting more fossil fuels from coal, oil, and gas to run our cars, trucks, and factories. By driving a “smarter” car, you will not only save on gas, but help prevent global warming. 4. There is more carbon dioxide in the atmosphere today than at any point in the last 800,000 years. 5. In total, the U.S. emits approximately 6 billion tons of carbon dioxide every year. 40% of that comes from power plant emissions alone. Echo Advertising : our Paper Bags Is ECO-FRIENDLY
