I think we do have a tendency, as a species, to get carried away with a good thing. If we discover that a little is good, than we immediately assume that a lot is even better. We also tend to be very reductionistic and want to extract that one great and powerful ingredient that is the true panacea for all our ills.
Unfortunately, we just don’t learn. We constantly persist in our wrong headed beliefs that we can always improve on mother nature despite repeated failures. Every time we think we’ve got the answer, she throws cold water on our unbalanced practices.
