I always find it funny when people say 'look how perfect the Earth is to support life' when in fact most species have evolved and adapted to the way the Earth is...If we lived on Mercury, we'd think Mercury was the only special planet that could support life the way we knew it
I feel we are looking at things backwards or upside down. The Earth didn't evolve to suit our needs, we evolved in such ways as to utilize Earths resources.
And the most important bit about this is that this adaptation to the Earth's resources have happened over billions of years. We didn't get to where we are in a couple of lifetimes. And I think its important to remember this because we are changing things on Earth - we are changing its nature.. Whether it's the atmosphere or the land or the water, everything is naturally changing and also changing because of us (humans). Change in itself is not a problem but the changes need to be slow so that we can adapt. Drastic changes only mean that we will have to cope better and have to work harder and faster to adjust to the world around us.
Whatever change we create should take effect slowly so that we (and other species on Earth) can adapt to the same.
