__//**My greenhouse effect speech **//__

//**__INTRO __**// The greenhouse effect is an enviromental issue. I am supporting that the green house effect is a bad thing and we should do something about it. Without the greenhouse effect the earth would be 60 degrees colder. The green house effect is the main souce of the extra heating on the earth. __We humans caused this with our man- made cars and factories and we can reduce it by putting less harmful polutants in the air.__

__//**The Cause Of The Green House Effect**//__ ​ The cause of the green house effect is in fact just to much carbon dioxide in the air. Carbon dioxide is the cause of the greenhouse effect because carbon dioxide grabs on to the heat in the air and that keeps us warm. With too much carbon dioxide it will keep us too warm. __We let gases into the air from cars, busses, and factories.__ Those gases are also containing the gas carbon dioxide(CO2). This is a topic and theory that scientist still fight about. There are scientist that agree that the green house effect is a //good// thing. But on the other hand, there are still scientist that //disagree.//

__//**What could happen**//__ Many years from now humans might become extinct. If we do not do anything about this, this theory might come true. We could keep using the same things that cause this horrible issue but nothing will change. It will be steaming hot in the summer and we will have temperatures like 70 and 80 degrees in the winter. This will become a disaster if we do not do anything about it. __This is caused by our cars and factories and we need to resolve this.__

__//**What we can do**//__ We created this monster and we can destroy it. Even though carbon dioxde caused this menace, we could still die from not having carbon dioxde. You see, we need carbon dioxide and without it lots of bad things would happen. Plants need to breath in carbon dioxide and they breath out oxygen which we need. Carbon dioxide also keeps us warm so we do not freeze to death. __We can make vehicles that run with less fuel. Our factories could burn less coal.__

 __//**Conclusion**//__ The green house effect is not the only enviromental issue. There is also air polution, water polution and even land polution. Our earth needs a new beginning. A very long time ago, our land on earth was nice and green. Our water was nice and blue. Now our land is brown and waters are black. __Cars and factories are putting harmful polutants in the air.__ Our forests are being burned down. We are putting harmful chemicals in our water ways. We need to stop the way we are living the way we are now and start appreciating what we have and what the earth provides us. If we keep living this way, "Bye, Bye Earth".
