Pending the launch of Trump: The World's Finest Super Premium Vodka next spring, I had thought the worst gift one could possibly receive would be a 3.4oz bottle of Donald Trump: The Fragrance. At least, that was until I learnt that many people this year will be waking up on Christmas morning to find themselves the unlucky recipients of a goat, a toilet or a ton of air pollution.

Often at Christmas there is a fad for something, be it hula-hoops, pet rocks or iPods. But this year, the fashion is to demonstrate one's philanthropy or concern for the environment by opting for ethical gifts that benefit poor people or the planet.
