A lot of African wildlife is very big. If you're protecting the big stuff, you're usually protecting the small stuff, too.

Helping Africans navigate the transition to modernity with a huge, wonderful wildlife resource still intact.

There's a place in Botswana where there are 100,000 elephants living in a single population. Think of the amount of space they need. Remember, the United States would fit in Africa three times over and there would still be space. That's how big Africa is.

These magnificent species of Africa - elephants, rhino, lions, leopards, cheetah, the great apes (Africa has four of the world's five great apes) - this is a treasure for all humanity, and they are not for sale. They are not for trade. They need to be valued and preserved by humanity. We all need a global commitment to that.

In most of the world, we have only small remnants of the wildlife that once existed. Africa has the most astonishing wildlife still.

We did a campaign here with New York Times. We had a great ad: "Today in America, someone will kill an elephant for a bracelet." We became sensitized in our society. Now there are four or five billion people in Asia who need to get this message. We need to use social media, print magazines, celebrities - anything we can to share this message. It's not cool, it's not okay. You are destroying beautiful animals. You are robbing a continent of its wealth. And you are hurting a lot of innocent people.

There's no space for wildlife; the humans are crowding them out.
