The Okavango needs your help

Today, for World Rivers Day, I'm thinking about one of the world's most pristine—and vulnerable—river systems: the Okavango River Basin.

The Okavango's delta in Botswana is home to elephants, big cats, giraffes, and so many other incredible species. Animals migrate there after being pushed out of their native ranges.

But the Okavango and the animals that have found refuge there are quickly coming under threat. The delta's upstream water supply is more vulnerable than ever to human interference. If we allow development to spoil it, the Okavango's wildlife and the people who depend on it will suffer.

Help explore and protect the Okavango Delta, the waters that feed it, and the animals that call the Okavango home by making a gift of $10 or more to the National Geographic Society in honor of World Rivers Day.
