Some 40 per cent of the earth's ice-free land mass is now intensively farmed to produce food. Only 12 per cent of its rivers run freely to the seas. Nearly one billion people go hungry every day; 1.5 billion are overweight or obese. Each year, more than 300,000 sea birds die on fishing lines and 100 million sharks are killed. Every square kilometre of sea contains 18,500 pieces of floating plastic.
