Here are some famous slogans-
1. Plant a tree, plant a tree, so that next generation can get air for free
2.Save Trees or else their leaves will only be seen in Museums.
3.Forests may be gorgeous but there is nothing more alive than a tree that learns how to grow in a cemetery.
4.People who will not sustain trees will soon live in a world
that will not sustain people.
5. Only after the last tree has been cut down, Only after the last river has been poisoned, Only after the last fish has been caught, Only then will you find that you cannot eat money.
