Bar Refaeli insists it's "important" to be green.
The Israeli supermodel - who is currently dating actor Leonardo DiCaprio - takes environmental issues seriously and isn't afraid to get her hands dirty; she even tries to pick up litter wherever she goes.
Refaeli explains, "I think the green issue is one of the most important because this is our future and my kids future and yours and everyone's.
"When I go to the beach I always clean up after myself and I clean around me too - what other people forget. The plastic bottles I even take home and recycle."
