Zac Efron: I Try to be Green as Much as I Can

Zac Efron heads back to his hotel after grabbing dinner at a nearby restaurant on Wednesday (March 7) in Madrid, Spain.

The 24-year-old actor has been busy promoting his animated movie, The Lorax, which recently topped the box office.

“I try to be green, as much as I can. It’s hard. I feel like I’m never doing enough,” Zac recently told TeenHollywood.com.

“I’ve always been searching for a way to get more involved and to help, and I felt like this movie, with the message that it has, was a really organic way to be able to help and get involved for me as an actor because there are only so many things you can do,” he added. “As they say in the movie it only takes one seed. So, I think we’re planting those seeds.”
