Methods for Global Warming by Eka Nurul Hidayah S (11150001)

I have three methods to decrease global warming. The first is you must decrease the usage of papers, because every piece of paper that you have used equals with a tree that is cut down. Second if you have computer, you must avoid screen saver. If you used it for long time or you will leave your computer on, screen saver spends a lot of energy and remove CO2. Third, you should decrease the usage of plastic bag. Plastic can damage environment and in fact the element can't decompose until 1000 years. Those way can decrease global warming effect for our better life.
