Former OC star Mischa Barton says she tries to remember three rules to save the environment.
Contactmusic.com reports that Barton takes the environment issues seriously and is also a spokesperson for Climate Star, an organisation that fights Global Warming through social and legislative activism.
She said: "The three everyday tips I like for staying green are - conserving water around the house. Don't leave water running for no reason, especially when you're brushing your teeth or taking a shower. Just do not waste water.
"Second, when you go to the store, most stores have bags that are reusable. Bring them back as long as you remember them, which seems to be my only issue. I think that's an amazing thing to do. It saves us paper and plastic and it's much, much, much better for the environment.
"The third thing I think everyone should try use bike and walk because not only is it good for you, it's really good for the environment, especially in places like LA where everyone drives. I have friends who drive hybrids and bio-diesel cars, but you know they're nothing like getting out there and going walking."
