Saving the planet one plateful at a time does not mean cutting back on meat, according to new research: the trick may be to switch our diet to insects and other creepy-crawlies.
The raising of livestock such as cows, pigs and sheep occupies two-thirds of the world’s farmland and generates 20% of all the greenhouse gases driving global warming. As a result, the United Nations and senior figures want to reduce the amount of meat we eat and the search is on for alternatives.
A policy paper on the eating of insects is being formally considered by the UN Food and Agriculture Organisation. The FAO held a meeting on the theme in Thailand in 2008 and there are plans for a world congress in 2013.
Professor Arnold van Huis, an entomologist at Wageningen University in Belgium and the author of the UN paper, says eating insects has advantages.
