Global issue-The energy crisis

  In the era,we use lots of energy for our life,like a oil is the most we need,but now it seems had a problem of exhaust for human beings to use,so we tried to found alternative energy,like the nuclear energy.But the nuclear energy wastes can't be decomposition,and it can damage to the ecology.So we tried to figure out the new energy,like solar energy.And i think everyone are suffer from this serious problem because we're all live in the earth.Although the energy cause global warming and lots of problems but we still can take some action to save the earth.Start from the place that everyone haven't notice,like turn off the light when you leave the room or use the air conditioner less than before and so on.You can do the 3R to protect the environment too.
