The prestigious scientific journal Nature (behind a paywall) has just issued a report with this bad news, news which scientists have warned about about over the last 40 years, and warnings that corporate shills have poo-pooed ever since.
The report, written by 22 scientists from three continents ahead of this year's Rio+20 summit, claims that the 'state shift' is likely; however, humans may have a small window to curb over-consumption, over-population growth and environmental destruction, with drastic efforts to change the way we live on planet earth through international cooperation.
