There was really no friendship in modeling though a certain amount of warmth comes from running into models you know on shoots because you end up in so many unfamiliar places from Alaska to Africa.

With nine degrees of warming computer models project that Australia will look like a disaster movie. Habitats for most vertebrates will vanish. Water supply to the Murray-Darling Basin will fall by half severely curtailing food production.

I have a lot of trouble understanding all the detail of finance and administration - but if you combine intellectual and professional capacity with a social conscience you can change things: countries structures economic models colonial states.

I'm learning as I go. I don't know everything. I never had anybody to look at nobody ever taught me and where I'm from I didn't have any famous role models.

Whole communities are growing up without fathers or male role models. Bringing up a family in the best of circumstances is not easy.

The leading cause of death among fashion models is falling through street grates.

I didn't have any role models really. My best friend was a dog. My mum and dad saved a dog from the gutter and that dog was my brother before Jesse was born. Sami was his name and he was my role model.

The older people that one admires seem to be fearless. They go right out into the world. It's astounding. Maybe they can't see or they can't hear but they walk out into the street and take life as it comes. They're models of courage in a strange way.
