What would you do for your planet's sake?

Basically it is not difficult if everybody thinks of it. Look, for example, if everyone plants a tree everytime he buys a new car, we will have much more forests in about 50 years. The world will look totally different. And it is not hard to plant a tree once in several years for most of the people. I am personnaly planning to plant a dosen of trees once I have bought myself a car.

Alot of people unfortuntely don't do anything. They just don't have the time or the knoweldge to really care, or think that even if they did stop doing things it would make a difference one way or another. I would use cloth diapers, recycle, walk as much as possible intstead of driving my car to the grocercy store or gas station. What would you all do?
