Debate continues to rage over how much of a population the earth can sustain

Experts have different views on how much of a population rise the earth can sustain, but many believe the crunch is approaching

The Easter Island and Angkor complex are among places where Jared Diamond believes civilisations thrived, then failed by overstraining environments.

After I sent my US biologist friend Dr James Lazell a recent column on global warming, he also suggested I write about human overpopulation. This seems a thornier issue for conservation than even climate change, as debates can feature religion, racism, eugenics and genocide.

Yet overpopulation has long been a concern to me, and seems timely in Hong Kong given arguments raging over mainland tourists dubbed "locusts", housing threats to country parks and outrageous plans such as building artificial islands for shopping malls, housing and a giant incinerator.
