Plant a tree

This action is the environmental equivalent of a Tae Bo video - old-fashioned but effective. If you'd like to connect your own tree planting to a larger project, you could give the UN Environment Programme's Billion Tree Campaign a whirl.


Effort involved: a decent amount of physical exertion, but it's all productive. Replace a workout with a planting session, and you're golden.
