What evidence would tell us if human population has exceeded the Earth's carrying capacity?


Earth's human population currently stands at 7 billion and is on target to double in 70 years. Clearly, it seems, at some point human population will be greater than the planet's resources--food, clean water, space--can bear. How might we know we have grown beyond the Earth's carrying capacity for our species?

    I would hope we altered course before reaching such signs of environmental collapse. I would agree Earth's carrying capacity in regard to our species is flexible. A global pandemic like the Black death of old could swat us down dramatically.

    i think the biggest buyers of farmland in NZ are the Swiss followed by Europe as a whole. China is not a big buyer.

    China has a One Child Policy for the past 30 years so they know something about the problems the future holds.
