Supermodel Petra Nemcova has become a vegan after reading up on the planet's fish problems. The stunning Czech Republic catwalk star reveals she gave up meat and dairy in February (07) because she wants to set an example and help save ocean life. Nemcova explains, "I became quite green... I have a very strong connection to nature... and I read that if we fish the way we fish, in 2048 there will be no more fish left, which is pretty soon. So it's a statement."
