Global Warming is a climate change in the atmosphere of the Earth. It is a gradual increase in the overall temperature of the earth’s atmosphere generally attributed to the green house effect caused by increased levels of carbon dioxide, CFCs, and other pollutants. It is believed by many people that humans are causing this change and are slowly killing the Earth because global warming hurts many people, animals, and plants. Many people also believe that humans are causing Polar Bears to go extinct because glaciers are melting because of global warming.
The greenhouse effect makes the earth appropriate for people to live on. If we didn’t have greenhouse gasses, then either the world would be freezing or would be burning hot. Even though the greenhouse effect makes the earth able to have people living on it, if there are too many gases, the earth can get unusually warmer and many plants, animals, and people can die because of this! You definitely do not want this to happen! People and animals would die because there would be less food for animals, like cows and grass, and therefore less food for us! Everyone could die of hunger!
Greenhouse gasses are gasses that collect heat and light from the sun. If there are too many greenhouse gasses in the air, then the earth’s atmosphere would get too hot. People, animals, and plants would die because of the heat. Global warming makes the sea rise and cover low land islands. Global Warming also kills life in oceans.
I think humans are contributing to global warming but are not the main reason of global warming. Humans contribute because of the pollution they cause. Things such as electricity (light, T.V., using a hair dryer, etc.), riding in a car, using a microwave, etc. cause global warming. When garbage is burned in landfills, it sends greenhouse gasses into the air.
Many people simply believe that global warming is natural and the Earth is actually cooling. Many people believe polar bears will not go extinct and humans aren’t a big cause of global warming! It is natural for the climate to change and temperatures will fall not rise!
Which side are you in the argument? I believe that humans are not the only cause of global warming, but we can still help!
