I don't think going dark will actually help. This is because we are entering the modern age, wind turbines and solar panels and stuff. If we just recognize the section of our energy that is from fossil fuels and ignore the fact that we are humans that are arriving into a new mindset, this is a bit impractical.
Forced evolution is critical! Elephants need the tusks to show off and defend themselves, but since the poaching is outweighing these issues in most elephant's DNA, this means no tusks. =( Darwin was right. Darwin was right.
