EVEN THE WORMS at WWF-UK are happy, as the conservation charity feeds its food waste into a wormery. Founded in 1961, it now has a mission "to stop the degradation of the planet's natural environment and to build a future in which humans live in harmony with nature". The 356 staff say the charity makes a real difference to the world (89% positive, the fourth highest score for mid-sized bodies), and does its bit for the environment (77%, the second highest score). wwf.org.uk
