We can apply green principles not just to our homes or work, but to all aspects of our lives, including our leisure time. For instance, can your sports club fit water-saving showerheads in the changerooms? Or can your organise car-pooling to away matches so you take as few cars as possible? And how about serving fewer beef at the sausage sizzle? In general, you should try to organise your leisure activities to do more locally so you reduce the distances you drive. And when you do travel, see if you can make the journey by public transport instead.
