New analysis shows populations of tropical species are plummeting and humanity’s demands on natural resources are sky-rocketing to 50 per cent more than the earth can sustain, reveals the 2010 edition of WWF’s Living Planet Report – the leading survey of the planet’s health.

The biennial report, produced in collaboration with the Zoological Society of London and the Global Footprint Network, uses the global Living Planet Index as a measure of the health of almost 8,000 populations of more than 2,500 species. The global Index shows a decrease by 30 per cent since 1970, with the tropics hardest hit showing a 60 per cent decline in less than 40 years.

“There is an alarming rate of biodiversity loss in low-income, often tropical countries while the developed world is living in a false paradise, fuelled by excessive consumption and high carbon emissions,” said Jim Leape, Director General of WWF International.
