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.

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.

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

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

A lot of African wildlife is very big. If you're protecting the big stuff, you're usually protecting the small stuff, too. One of the main things we advocate for is for countries to set aside, even if it's fewer places, really big places, so that you can have viable populations.

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.
