The UK launch of the UN-supported International Year of the Co-operatives is today, so watch out for activities up and down the country. I've joined the Mid-counties Co-operative a couple of years ago - think it was after writing this piece about bees problems and their "Plan Bee" initiative, which drew my attention to their membership info, which has a nice honeycomb design (as has my membership card).

Last year I also switched my energy supply to the newly founded cooperative energy, and started moving my finances from a bailed-out bank to a cooperatively owned one. Still a few thing left to switch (such as insurances), but I find it hugely comforting in these scary times that we can actually stop feeding the fat cats and support the existing alternatives to predatory capitalism, including cooperative businesses and fairtrade products.
