The Amazon needs to be protected but I think we need to be reasonable. We really fool ourselves into believing the most silly things about the world; the number one misconception being that the world the way it is, is the way was and the way it should always and forever be. People have been worried about overpopulation for so long and I wish I could be worried but I'm not. It is like worrying about whether it will rain too much. If it does it floods, if a population expands beyond its means people die.
Humanity responds with more innovation and so far the innovation has outpaced the doomsayers and it is abundantly clear from history that had humanity heeded the doomsayers, the dire prophecies wouldve likely have come true because the innovation, the eyes on the horizon, wouldve been sacrificed to the hording of scraps and perpetual poverty of communism. Just as you can not avoid a ditch by focusing solely on it one can not avoid disaster by dwelling on it.
Conservative or not we will not conserve the rain forest by telling poor indians they are better off without houses and running water.
Perpetual Dismay
We need not hope for the end of the world
And nor can we know the day
But to so fixate ourselves on doom
Can only lead our hearts to one place-
The empty comfort of perpetual dismay.
Something I have been trying to get across for years. You can't manage for a static planet. That said, the most important thing is not to oppose change but rather work with change and allow organism to be able to 'naturally' respond to them.
