What did you do over the weekend ?   I went a global warming rally . It was fantastic to be around so many people who care about the environment .   Do you think there's anything we can do to reverse the damage that's been done already ?   It might not be possible to fix the problems that we've created for ourselves , but there are lots of things we can do to prevent more damages from happening .   Like what ?   Well , we can use public transport instead of taking our cars for a start .   What else can we do to protect the environment ?   If you do have to drive , you should make sure that your car runs on unleaded petrol . Also , your home should use sources of renewable energy .   How about recycling ? Does that actually help ?
