Diversity will drop dramatically before vacant niches encourage a rebound diversity increase. What will that cost us? - How will that affect our survivability. - What are the ethical costs?

Interesting....on all counts. Especially in terms of costs. Since we cannot, to any significant degree, control global warming or cooling, can we adapt quickly enough to survive over other species who have already physically adapted?

The probability of that is 1. We are here.
