No doubt the increasing human population is putting a huge dent on the environment. The capacity is no longer holding and natural resources are fast depleting. Still exploitation of the environment is increasing as the human population is increasing. I think humans If stopped breeding (not completely though as that would mean extinction) but in a systematically controlled pattern, we would be able to manage the environment and resources in a way that would sustain humans for longevity. This is reminds of the "one child policy" in China from 1979. This was a temporary measure to help balance economic growth and rapid population growth. Human population is definitely a pobelm. We can not eliminate humans to reduce the population but we can definitely minimize birth rate.
