Whatever my current beliefs are, on any topic, they're all open to being changed by the right facts and the right evidence.

Playing God is actually the highest expression of human nature. The urges to improve ourselves, to master our environment, and to set our children on the best path possible have been the fundamental driving forces of all of human history. Without these urges to ‘play God’, the world as we know it wouldn’t exist today.

Doom yourself to horrific climate change by burning all that carbon and releasing all that CO2. Or power down society, reducing total energy usage around the planet. One leads to ecological collapse. The other is a reversion, in many ways, to poverty.

If the incentives are aligned right - towards better preservation and restoration of nature and natural resources - then you'll see a tremendous amount of activity in that direction.

In the food case in particular, one of the technologies that could help there - genetic technologies that could create better crops with higher yields and less need for water and fertilizer - is tremendously feared. Very little of that fear is scientifically grounded.

There are really two kinds of optimism. There's the complacent, Pollyanna optimism that says "don't worry - everything will be just fine" and that allows one to just lay back and do nothing about the problems around you. Then there's what we call dynamic optimism. That's an optimism based on action.
