The Splash and Kill Bill actress, who has been arrested several times for her work as an environmental activist, said that it only takes small changes to make a difference to the future of our planet.
Hannah told The Sun: "There are so many things that everybody can do. Am I going to get some food in a Styrofoam container?
"Or am I going to bring my own cup and my own cutlery set and say I won't participate in a disposable society?
"I sense that youth culture has taken up the call. Almost everybody could grow seeds in their garden or on their window. All that stuff that poisons the air, the soil and the water - it should be against the fricking law!"
