Deforestation could wipe out one-fifth of species
Singapore survey reveals conservation crisis on Southeast Asia

"Up to one-fifth of the world's plant and animal species could be wiped out within 100 years by deforestation in Southeast Asia, according to a survey of extinction rates in Singapore.
This bleak prognosis calls for tough conservation measures, says Barry Brook of the Northern Territory University in Darwin, Australia, who led the study. 'If we don't do anything, things will unfold in a very unpleasant way,' he predicts.
EDIT
A small, highly urbanized nation, Singapore probably represents a worst-case scenario for habitat loss. But its less-developed neighbours are in danger of inflicting similar damage on their own rainforests. Malaysia, for example, has already lost 60% of its forests.
EDIT
Of Singapore's remaining plants and animals, more than half dwell in reserves covering just 0.25% of the island's area. Such fragments are valuable. The Bukit Timah reserve, for example, covers only ten square kilometres yet contains as many tree, flower and grass species as Great Britain."
