According to the International Union for Conservation of Nature’s report, one out of every four species of mammals is facing extinction. Many of the most threatened species are found in Asia, a continent with a growing human population.
“This is leading to habitat loss due to agricultural expansion; development of infrastructure such as roads, which fragment critical landscapes; and increasing areas for industrial crops such as oil palm and pulp for paper,” said Barney Long, a biologist at the World Wildlife Fund in Washington, D.C.
Worldwide, habitat loss affects about 40 percent of threatened mammal species, while human hunting affects 17 percent, Long said.
There is hope for mammals, but keeping them off the endangered list will take a lot of hard work. According to the report, 5 percent of threatened species have seen rebounds due to conservation efforts.
