I am convinced that the human race is doomed, and sooner rather than later. For whatever reason, we have become a species that thinks it knows better than natural selection. The lengths we go to to keep individuals alive and in the gene pool, or to allow people to reproduce who could not without "interference"...
I was thinking about this the other day. Even on a small level - like dentistry. Without interference, someone with bad teeth might not have survived to reproduce because of pain or difficulty with eating. This would eventually weed out the "bad teeth gene". But not any more.
As a species, in general, we value individual lives to the detriment of the species as a whole. And this will be our downfall.
Well that and ruining the planet
