Global Warming
Our only home is the earth. “And that’s what is at stake, our ability to live on planet earth, to have a future as a civilization. I believe this is a moral issue, it is your time to cease this issue, and it is our time to rise again to secure our future,” said former Vice-President Al Gore. Al Gore made a speech about global warming and said how to keep it healthy. The earth can be kept healthy and exist longer without global warming. Global warming is becoming a popular topic around the world. “Global Warming and the Greenhouse Effect” discusses what global warming is. This is how global warming is caused. Energy travels from the sun to the earth to heat it. The earth then radiates energy back into space. If the planet radiates energy back into space at the same rate it receives energy, its temperature stays the same (“Global Warming” 1). However, many gases, called greenhouse gases, are being put into the air. The increased amount of greenhouse gasses contributes to global warming (1). Greenhouse gases absorb some of the outgoing energy and send it back to earth (1). If the greenhouse gases send back energy for long amounts of time, the earth heats up, thus making the earth warm up. The earth is not healthy when it keeps heating up, making a problem. Global warming is a problem. Many human activities are sending high amounts of greenhouse gases into the atmosphere (Global Warming 1). Driving a car means that carbon monoxide – a greenhouse gas – is being emitted into the air. Another problem is that the trees in rainforests are being cut down (Shnayerson 7). Trees take in carbon dioxide. With fewer trees there is more carbon dioxide in the air. The earth is increasing rapidly in temperature (1). This is what global warming is, the heating of the earth. The increasing temperature has several effects on the earth and it inhabitants. Global warming has an impact on the world, especially wildlife. The Bush administration recommended
