An ingredient used in everything from Oreos to shampoo to margarine is killing some of the world's rarest animals. Now, companies are starting to see that it's bad for business, too.
Palm oil, found in roughly half of all supermarket household items and packaged foods, is often produced on enormous plantations that have displaced miles of pristine forest. Mainly in Southeast Asia, these forests were once home to endangered orangutans, elephants, rhinos, reptiles and others.
Orangutans in particular have been hit hard - almost 80 percent of their habitat has disappeared over the last 20 years. Each year, palm oil development kills an estimated 1,000 to 5,000 orangutans, who die when their trees are cut down or their food sources are cut off during development. Others are brought to rescue centers, where rescuers scramble to take them in or relocate them.
