Why would a decline of sum(humans) even be a problem? We have destroyed large swathes of our habitats, poisoned the air, land and water not only where we live but also where we get our resources, exploit and kill each other because of a skydaddy or for financial gain, and delude ourselves into thinking we're a gift to this earth or even the universe. How we can even think that putting more consumers on this planet is good for the environment is beyond me. The best way to stop polluting is to consume less. The max minimum of consumption is an absence of consumption. We don't need more people, we need less of them. And if education and prosperity is making us recognize that, then I demand more education and more prosperity worldwide.
