Darwinan evolution is limited to the biological aspect but before that happened the molecules themselves had to evolve to enable this further (biological) evolution.

Modifying ourselves is a natural process because we are a product of nature and what we do is a product of nature. Therefore, if one day we have three time bigger brain and two hearts instead of one (because one is not enough) then this is all part of nature.

We can look at the way of improving the key biochemical processes like photosynthesis itself. A lot of energy is lost to keep the plant cool. So maybe we can think of building plants which are more resistant to heat. Genetically modified plants can be one answer and we can imagine more efficient plants, call them 'energy plants'. And I believe, contrary to what ecologists think, they can still be beautiful plants.

Science has nothing to do with any dogma. Science ceases to exist when there is a dogma.

The pace at which science has progressed has been too fast for human behaviour to adapt to it. As I said we are still apes. A part of our brain is still a paleo-brain and many of the reactions come from our fight or flight instinct. As long as this part of the brain can take over control the rational part of the brain (we will face these problems).

Think that you are part of a big construction called science and you are not just a chemist but you are scientist. Be modest but proud. Modest because you know you will not be able to solve other problems because your life is too short. But be proud because you are contributing to it. Some people will bring a small stone to the building and some people will bring a big one but nevertheless no one can take that stone away from you.
