Shopping ethically can be tough at the best times, never mind with the pressure and rush around Christmas. The gift ideas below will make your task that little bit easier, saving you time, money and helping the environment. Books are a real favourite at Christmas. It's always best to try and buy second-hand books saving you money and trees. We would recommend that you use Oxfam or Better World Books, where book sales go to charity. Or use your local second-hand bookshop.
