WATER: Do we know the figures behind today's water consumption? For example, cotton from the fashion industry accounts for 10 per cent of global CO2 emissions – more than aviation and shipping combined. It costs 2700 liters of water to produce a cotton T-shirt. 140 liters of water to produce a cup of coffee. And one kilogram of beef requires a whopping 14 liters of water. Must we always let capitalism trump the future?
