Bindi Irwin, Youth Ambassador

Bindi is the daughter of the original Wildlife Warrior and conservationist Steve Irwin. Bindi, who has inherited her father’s love of animals, is an actress and television presenter who calls the Sunshine Coast’s iconic Australia Zoo home.

In responding to the request by former US Secretary of State Hillary Clinton's endangered species initiative, to say why she had devoted her life to wildlife conservation, Bindi wrote:

I believe that most problems in the world today, such as climate change, stem from one immense problem which seems to be the elephant in the room that no-one wants to talk about. This problem is our ever expanding human population. We are experiencing Earth's sixth mass extinction right now. Keep in mind that the previous five were caused by things like asteroid impacts or volcanic eruptions.

Bindi understands the link between growth in population and habitat decline. Retention of quality and quantity of habitat is essential for other species’ health and survival.
