we can still do something like be wise on the use of oil, electricity, and we also can plant trees, don't cut trees in the forest, don't build too many buildings, don't use too many transportations (why prefer using transportation in a near place?), and many others.
so the chance is in individuals and the government. if we can work together to save this place, and don't forget to pray, insyaa Allah this planet will be safe.
it is really not late of saving earth let start now. many people do not think of what will happen next when the world is gone. some people do not even care about the nature. people continue cutting trees and they do not even care to replace it. there are programs for saving earth but they do nof participate in it.
