We each owe the Earth 16 trees

I you want to put back into the atmosphere the oxygen you will breath in a lifetime, take out your spade and plant some trees.

You will also help offset the climate-changing carbon dioxide you pump into the air by urban living, each time you drive a car or switch on a light.

It takes 16 trees to supply the oxygen for one person’s life. So we each owe the Earth 16 trees.
