We could use a law like this in the U.S. to help fight climate change. If our idiot president is going to allow more polluters to pollute more, then we need more trees to counter act that.
Why limit it to students ? How about govt employees wanting a raise/promotion, for example ?
If we are going to require government employees to do it, I say lets hit up persons running for office (politicians) requiring them to plant trees in order to be eligible to run, and not just the first time they run, but every time.
