Insects, snakes and lizards could be the secret to cure a global food crisis, as available land and water resources shrink, and climate-change takes effect.

The United Nations Food and Agricultural Organisation (FAO) is encouraging eating insects where malnutrition and starvation occurring and to help combat obesity. In South America and east Asia, where people have eaten insects for millennia, the news has been warmly welcomed. But in the West, cooking with insects is still far from accepted: despite some chefs' attempts to change people's minds.
