Question

How does overpopulation in South America impact global warming?

Answer 1

Well overpopulation puts huge dent in available food supplies. This results in deforestation to make both farmland and lumber for building to house everyone. deforestation create CO2, and depletes vegetation which would have absorbed CO2

Another is that more people means the need for more electricity which is produced in most nations (including ours) by the burning of fossil fuels releasing CO2.

A third is more people mean more cars and hence more CO2

Fourth, although not all countries are as wasteful as ours, they produce sewage and garbage, both of which release Methane into the air.

Then of course more people means more consumer goods required and their manufacture results in more CO2 and God knows what else being released.

Answer 2

Thank you! :)
