Because pollution in a simple since is unavoidable. it is not an issue of social consciousness but rather of existence. And since every means which we reduce the load of pollution on the world only induces a higher proportion of people to be brought into the world would it suffice to say that we must let the problem intensify in order for a reaction to occur. or is that reaction occurring. Current conservation through education, does it work. Will Legislation work? Or would unaltered behavior be best. By allowing the unforeseen to regulate.
Uh...and HOW does doing stuff to help stop this catastrophe make it worse? And inevitable that well breed? Education work? Well yeah...
But allowing and welcoming the population to naturally grow, helps along the already population-driven technology growth, which in turn helps reduce pollution, so it naturally works itself out, especially with good leadership, to help the human race expand as it was meant to. As I have heard, human population only seems to go up. Could be that it simply because, it's the way things are meant to be. And we get used to it and move on, and often don't even notice at all. But behavior is important too. With more people in the world, it's all the more important to promote the social graces, hold doors open for people, be polite, and use turn signals and trash cans, people. Think of your many neighbors, and what's good for them too.
Nothing is meant to be, stuff just is. God, -whom you are not- what religion are you. What do you know of my neighbors, they make me seethe with disgust.
We can't stop pooping. We'd die. Although that may be helpful to the environment as well. You know, I'm pretty sure poop is biodegradable as well...
I say it's time to educate people about the ills of breeding... And if diplomacy doesn't work, we ridicule and even tax the living daylights out of the breeders.
