We animals account for a paltry 0.3% of the planet's biomass while plants add up to 85%. And when, with just a little training, we are able to look at the world without seeing it solely as humanity's playground, we cannot help but notice the ubiquity of plants. They are everywhere, and their stories are inevitably bound up with ours. As every tree in a forest is linked to all the others by an underground network of roots, uniting them to form a super organism, so plants constitute the nervous system, the plan that is the greenprint of our world. To ignore the existence of this plan is one of the most serious threats to the survival of our species.
