Global food crisis: 7 insects we'll be eating in the future

As the human population continues to inch closer to 8 billion people, feeding all those hungry mouths will become increasingly difficult. A growing number of experts claim that people will soon have no choice but to consume insects.

As if to underscore that claim, a group of students from McGill University in Montreal has won the 2013 Hult Prize, for producing a protein-rich flour made from insects. The prize gives the students $1 million in seed money to begin creating what they call Power Flour. 

Earlier this year, the Food and Agriculture Organization of the United Nations (FAO) released a report titled, "Edible Insects: Future Prospects for Food and Feed Security." The document details the health and environmental benefits derived from a diet supplemented by insects, a diet also known as "entomophagy." Gleaned from the FAO document and other sources, here's a list of seven edible insects you may soon find on your dinner plate.

"We will be starting with grasshoppers," team captain Mohammed Ashour told ABC News.

He noted that the insect is already familiar to the local diet and currently sells at a premium because of a three-month harvesting season and because grasshoppers are typically hand-picked. But farmers have already expressed interest in raising grasshoppers on a mass level, according to Ashour.

While for Americans the idea of eating bugs remains mostly a novelty, in other areas of the world they are a common form of protein. The kinds of insects people consume from country to country varies, with the people of Ghana preferring palm weevils and in Botswana, caterpillars. The Power Flour product will vary ingredients according to those habits, adjusting production to the breeding cycles and nutritional profile of each culture.

In order to research their business plan, the members of the McGill Hult team have all consumed "kilos" of insects themselves, Ashour said.
