The former presidential candidate Al Gore presents a documentary movie about "global warming". Al Gore collected his information's by traveling around the world to let the people know what are the risks of this problem is. He talks about how people are the main reason to increase the danger of this issue; he also machined some solution for it.
Al Gore present many reasons to cause global warming, first one is increasing in the carbon dioxide level, which trap heat in the atmosphere and that will rise the temperature of the earth.
With the increase of the temperature the oceans will be warmer and that will lead to create hurricanes like Katrina. Also with the temperature rise it will lead to melt the North Pole ice and that will raise the sea level which can floods many coastal cities. Another problem is changing in the climate all over the world when the water of oceans and melted ice mixed together.
Al Gore also suggested several solutions for the global warming issue. The first one is planting green trees (vegetation), which will reduce the carbon dioxide and keep the atmosphere clean. Second, try to use renewable energy sources which do not pollute our earth.
Finally, the countries from all over the world have to step together to face this major problem.
To conclude, every one of us must help in this problem because we live in the same planet, all countries must co-operate in addition to solve or even reduce the causes of global warming.
