"This is our home and it's fragile and it's beautiful but it's also really in danger," he says in a new short film for Hope08.

Turning his attention to the "crisis of poverty" and the "huge gap" between the rich and the poor, McLaren states in the video message, "It's an unsustainable system when you have a gap like that."

"A friend of mine says there are really only two tribes in this world: there are the haves and the have-nots," he says. "The hope that we are looking for in the world involves both of them. It involves the have-nots not giving up and it involves the haves learning to care."

Mclaren shares in the film his personal story of reaching out to his Muslim neighbors in the days following the terrorist attack on the World Trade Center in New York by sending a letter and making visits to local mosques to reassure them of his support.
