Two enviro groups are launching a major campaign today to halt illegal logging that is threatening endangered orangutans in Indonesian national parks. About 80 percent of the orangutans’ forest habitat has been destroyed in the last 20 years, and the animals’ numbers have been halved in the last decade to no more than 25,000, according to a report produced by the Indonesian enviro group Telapak and the London-based Environmental Investigation Agency. Other species at risk from the logging include tigers, rhinos, elephants, clouded leopards, and sun bears. The groups say that corrupt officials have allowed illegal logging to flourish and even surpass legal logging in the nation.
