Have humans reached a point in population size that makes us an ecological pest?- Is the world’s human population already creating ecological problems or disasters?- Do we need to stop human population growth, as China did with its one-child policy, and protect the ecology of Earth?- Do you think the world’s human population has exceeded its carrying capacity on Earth? – How can we control human births if human reproduction is biologically natural?
