The orangutan's distribution has been steadily declining over the years. While exact orangutan population counts are always a challenge – various estimates put current counts at between 50,000-65,000 orangutans left in the wild – we do know with certainty that 2,000 to 3,000 orangutans are killed every year. Its ancestors' remains have been found in 14 million-year-old deposits in Punjab, India. Fossil remains also show that a giant race of orangutans existed in China 500,000 years ago. They also lived as far south as Java. Today the population is restricted to parts of Borneo and the north of Sumatra. In Borneo, its range has come under further threat from the forest fires of recent years, which destroyed millions of hectares of rainforest, killing many orangutans, and driving others into the open, forcing them to beg from humans for food.
