Global warming is one of the foremost problems facing our planet today. As pollution rises the ozone layer breaks down, and as the temperatures go on a constant rise glaciers and ice-caps melt. Many people have their doubts about the global warming "theory", however proof of this "theory" is evident all over the world. The environment is changing in many rapid ways and aside from affecting the planet, global warming has and will continue to affect the lives of human greatly if not stopped.
             In order to prevent global warming, people must first know what causes global warming. A well-known cause of global warming is the burning of fossil fuels. When people burn fossil fuels it releases methane, which is naturally stored underground, but when fossil fuels are released it goes upwards. Methane is a greenhouse gas and that means that it keeps heat stored up within the Earth's atmosphere. Methane gas is extremely harmful to the ozone and breaks it down causing holes in the ozone. The burning of fossil fuels can and needs to be stopped, because it is a man-made occurrence and does not happen naturally. Methane does get released into the air in extreme climatic areas such as wetlands and tundra's, but the amount is not to the extent that humans burn out methane. Changes must be made in order for humans to adapt to these climate changes because any change from 0 degrees Celsius to 5 degrees Celsius are dangerous to human society. Without greenhouse effect, the earth would be very cold. However, if the greenhouse effect becomes too strong, it will cause temperatures higher than usual posing threats to plants, animals and even humans.

             With pollution on the rise this means more people are driving cars. Cars release gases of their own and pollute the environment. Every car gives off i...
