'The Sumatran rainforest will mostly disappear within 20 years'

John Vidal in the globaldevelopment blog in the Guardian (UK): The end is in sight for the great forests of Sumatra and Borneo and the animals and people who depend on them. Thirty years ago the world's third- and sixth-largest islands were full of tigers, elephants, rhinos, orangutan and exotic birds and plants but in a frenzy of development they have been trashed in a single generation by global agribusiness and pulp and paper industries.

Their plantations supply Britain and the world with toilet paper, biofuels and vegetable oil to make everyday foods such as margarine, cream cheese and chocolate, but distraught scientists and environmental groups this week warn that one of the 21st century's greatest ecological disasters is rapidly unfolding.

Official figures show more than half of Indonesia's rainforest, the third-largest swath in the world, has been felled in a few years and permission has been granted to convert up to 70% of what remains into palm or acacia plantations. The government last week renewed a moratorium on the felling of rainforest, but nearly a million hectares are still being cut each year and the last pristine areas, in provinces such as Ache and Papua, are now prime targets for giant logging, palm and mining companies.

The toll on wildlife across an area nearly the size of Europe is vast, say scientists who warn that many of Indonesia's species could be extinct in the wild within 20-30 years. Orangutan numbers are in precipitous decline, only 250-400 tigers remain and fewer than 100 rhino are left in the forests, said the International Union for Conservation of Nature.

Millions of hectares are nominally protected, but the forest is fragmented, national parks are surrounded by plantations, illegal loggers work with impunity and corruption is rife in government....
