The greatest danger from human population growth is the extinction of species; mainly around the rainforests for it's diversity.
The mitigating steps humans can take on it's quest for life quality is:
1) Domicile's in a vertical plane. We can build taller buildings faster than we can birth a new generation.
2) Food production innovation. Grow food in less space by efficiency.
Design economic structures where the opportunity index gives more
incentive for growing populations to preserve our precious ecosystems,
especially subtropical ones.
