  • The world's population is projected to reach 11 billion by the end of the century. Feeding

  • that many people will be a challenge, and it is further complicated by the impact of

  • climate change on agriculture. That is why some people advocate an unusual way to boost

  • the food supply and feed people sustainably: by eating less meat, and more insects.

  • About 2 billion people already eat bugs. Mexicans enjoy chili-toast grasshoppers. Thais tucking

  • to cricket stir-fries and Ghanians snack on termites. Insects are slowly creeping onto

  • Western menus as novelty items, but most people remain squeamish. Yet there are three reasons

  • why eating insects make sense.

  • First, they are healthier than meat. There are nearly 2,000 kinds of edible insects,

  • many of them packed with protein, calcium, fibre, iron and zinc. A small serving of crickets

  • can contain the same or more protein as similarly sized serving of beef, but have half

  • the fat and far fewer calories.

  • Second, raising insects is cheap, or free. Little technology or investment is needed

  • to produce them. Harvesting insects could provide livelihoods to some of the world’s

  • poorest people.

  • Finally, insects are a far more sustainable source of food than livestock. Livestock production

  • accounts for nearly a fifth of all greenhouse-gas emissionsthat’s more than transport.

  • By contrast, insects produce relatively fewer greenhouse gases, and raising them requires

  • much less land and water. And they'll eat almost anything.

  • Despite all this, most Westerners find insects hard to swallow. One solution is to use protein

  • extracted from bugs in other products, such as ready meals and pasta sauces. Not having

  • to look at the bugs, and emphasis on the environmental benefits, might make the idea of eating insects

  • a bit more palatable.
