Full disclosure - I love trees.  In fact, I just planted five more of them in my garden last month.  Which means there are now approximately three trillion and five trees in the world!  Yep, you read that correctly three trillion and five!!!!! 

More interestingly, whether three trillion is accurate or not (and there is furious debate about that number in environmental academic communities) is the possibility that planting more trees could do a great deal to help us combat climate change.  

And, if you plant saplings, it is a relatively inexpensive way to take carbon out of the atmosphere.  Which sounds so easy - every single one of us could do this today if we put our minds to it.  Or like Elon Musk, Susan Wojcicki and many Silicon Valley behemoths (who some might say are amongst the most significant users of energy and consequently massive polluters of the planet) we could donate money to someone else to do the digging.  

The question is - can we plant enough trees, quickly enough to make a difference?   Or is it already too late? 

This long, detailed but utterly fascinating article from Tortoise Media tells you everything you need to know (and more!) about the place of Trees in the fight against climate change.
