If dogs contributed to or enabled our success, it does not mean that they are responsible for humans destroying the biosphere. However, their history will come to an end, through no fault of their own, when humans torch the planet. Obviously, humans ought to stop destroying the planet for many reasons. One more reason is that we shouldn’t do that to dogs. The human canine coevolution is unique on the planet, two species choosing to be together and being wildly successful, more than either would be alone. We shouldn’t destroy that unique relationship by destroying the planet. We certainly have the knowledge and the ability to stop killing the earth, if we just find the will. We shouldn’t waste the gift we have been given. It shouldn’t be the dog’s legacy that dogs invented humans and humans blew up the world.
