THE Earth is within decades of reaching an irreversible tipping point that could result in “planetary collapse”, scientists warned yesterday.
They called for drastic action, such as rapid curbs on population growth, to prevent food supplies being threatened by major changes to farming caused by climate change.
A team of 22 scientists reached the conclusion by comparing the biological impact of past major global changes with current patterns.
The warning comes two weeks before the United Nations Earth Summit in Rio de Janeiro, which marks the 20th anniversary of the landmark Brazil meeting.
According to the researchers, the report contradicted the belief that global collapse would be gradual or centuries away.
Anthony Barnosky, professor of integrative biology at the University of California, Berkeley, who led the research, said: “There will be a reduction in biodiversity and severe impacts on much of what we depend on to sustain our quality of life, including fisheries, agriculture, forest products and clean water.
“This could happen within just a few generations. The root cause, ultimately, is human population growth and how many resources each one of us uses.”

Realistic doom, guys (population growth, food resources, climate change...). I thought about this more than once.
What do you think?
