Technology and medicine are good things. But unfortunately its two sides of that coin. Evolution is intended to be accompanied by a natural way of life and die off of a species. Allowing for the next generation to live and develop. Since we are living longer and longer and effected more and more by technology, that natural process has become completely artificial.So just let every one who is sick suffer and die? Lets see how well you do without the aid of doctors and other people who are helping "kill our next step in evolution."
As a result our environment is negatively effected. Especially if you consider the way we have such disregard for it.
And the planet is rejecting it.
