It's a mental disease afflicting people of this generation. My generation venerated trees and would only fell one if absolutely necessary. The present crop of caring vegetable munching climate conscious clowns concrete and pave over their gardens and fell trees with a vengeance and are so full of hatred for almost everything and everyone, their antics beggar belief. It makes no sense but then this particular mob haven't made any sense since they first swallowed the idiotic claim that they were morally superior to everyone else and children were the teachers of the world.
One must just ride out the first two decades of any new century as these are invariably characterised with the rot that decayed the last years of the foregoing century. We are nearing the tipping point which is 2020. After that they will drive themselves over a cliff. Make sure you stay well clear or they will take you with them.
I can see the public becoming more angry with them and starting to rebel against their bullshit. Give it a bit more time and they will implode.
