Introduction to Global Warming

The Global Warming is the most important environmental problem in the world. It caused by green house gasses that are emits from Power Plants, Cars, Airplanes and even buildings. These gasses spread in the atmosphere around the globe forming a very thin layer that let the sunlights through that layer but not out from it which keeps the temperature raising. What if the temperature is kept rising? All the ice in both polar areas will melt and the seas will flood over the coastal cities and even more areas of the land will be flooded. We can avoid this disaster by reducing the amount of green house emitted in the atmosphere. I think it is an international problem. Moreover, every one should help in solving it forever. Scientists found the solutions but there is no serious action for solving that problem. Using of solar energy instead of power plants for generating electricity is one of these solutions. We should do something before it is too late.
