More and more people nowadays are aware of the dangers that threaten our natural world and decide to go [?] green to help save it from destruction. In fact, every one of us can make a difference if we decide to sort [?] out litter or save water and electricity at home. When shopping, don;t ask for a plastic bag but use paper bags instead. But if you really care about the natural environment, why not join an environmental organisation. like Greenpeace and become an activist?
