As countries mature the birth rate declines.

A global approach is essential. We can no longer live complacently thinking like individuals rather than like groups and nations. I keep seeing that quote: "There is no Planet B". We need to care and act on a much larger scale. I don't have the answers to how this will happen or even if this will happen...but the human race has to wake up and act. Maybe it could start with more public health education, which should include Ecology and Sustainability Practices. Corporations and industries will need to have incentives for going green and penalties for polluting and wasting resources. And our politicians will need to be better educated about these world population findings. So many of them seem blind, ignorant and resistant to policies that will decrease risks to our planet (and all the earthlings who will suffer.)

There's no fucking way the planet can sustain that many people for very long.......
