The Greenhouse Effect is a very essential part of our survival. It is what keeps humans warm at night and protects them from the sun during the day. What happens is that the gases in the atmosphere, carbon dioxide and methane, keep sunlight and warmth in the atmosphere by redirecting it back at the earth. This helps humans stay warm when we don’t have any direct sunlight on us. Also, it makes the sunlight less harmful and strong during the day so that we don’t overheat. If it was too small then we would freeze because all the heat would be released. There is no direct sunlight during the night either so we would have no source of heat.
 * __Why is the Greenhouse Effect Important? __ **

Global warming is the environment becoming polluted and the atmosphere becoming thicker. This results in the weather becoming hotter and hotter over time. That means that we have very hot summers and not as cold as they used to be winters. This is not good because the glaciers are melting and raising sea levels. This helps erosion and is destroying many islands and sea shores. If this continues then eventually islands will be wiped out and many people will lose there homes. Also, it causes the air to be polluted. This causes more carbon dioxide and less oxygen. Humans need oxygen to breath so this would be bad for survival.
 * __ Global Warming is Harming the Earth __ **

There are many different causes for Global Warming. One reason is because the carbon dioxide level is increasing and making the atmosphere thicker. Carbon dioxide is increased by cars letting off gas emissions that have carbon dioxide in them. Also, power plants let off gas emissions that have great amounts of carbon dioxide. They let of the carbon dioxide because of the electricity generators. Also, the increase of methane in the atmosphere causes it too. When any animal, including us, poop or let out gas in any way we are contributing to global warming. This is because our gas has methane in it and we let it out consistently. Water vapor is also a big contributor. It is increased because the carbon dioxide level makes the atmosphere hotter. The water vapor is making the atmosphere thicker too. false
 * __ Things Causing Global Warming __ **

__**Global Warming Effects on Boston **__ This could eventually happen to Boston and other citys.
 * In the Boston area, water levels should get so high that storms will flood the city. By the end of the century if there is a storm sea water will flood the financial district and most of the black bay. Then the effects of Boston would spread throughout the whole city and to other towns. It would reach Rockport and Duxbury first. If this happened then the whole city of Boston and other ****towns would have there buildings ruined and the people in them would have no places to live. Then many of the homeless people would die. This would be a huge tragedy. Also, if this happened then the city would have to repair it and it would cost over 94 billion dollars! **

__**My Family Improving the Enviorment **__ The one thing that can be done differently to improve the environment is directed to my family and friends. One thing that can be done differently is not driving in cars as much. My family and my friends always get rides to places when they are only one or two blocks away. Also, once you get to the place right around the corner, you have to drive back too. This is very harmful to the environment and it is really unnecessary to even do the driving. This is a chart of the average temperature increasing.

By doing all of this driving it is producing carbon dioxide that goes into the atmosphere. This is making the atmosphere thicker which helps keep the heat in. By keeping the heat in it is causing the glaciers to melt and they will eventually flood cities. Instead of driving people could walk, ride bikes, skateboard, scooter, or other way of getting there without gas. Also, people could use hybrid cars that have eclectic batteries that are used. This doesn’t use gas and doesn’t let off carbon dioxide that pollutes the air.  The Greenhouse Effect is very important for human survival. It is the thing that keeps us warm during the night and not too hot during the day. Global Warming is what is melting the Glaciers which are causing sea levels to rise. Therefore, the sea water is eroding land and could possibly flood coastal cities. All in all, we want the Greenhouse Effect and Global Warming to go away.
