Don't let the yuckiness bug you

By 2050, the world’s population is expected to rise to 9 billion, and there are fears that this will lead to an increase in world hunger and food shortages. The UN Food and Agriculture Organization (FAO) estimates that food production will need to increase by 70% if we want to feed the growing population. Seeing as it isn’t ethically viable to somehow put a halt to this population growth or get rid of half of the world’s existing population, our best call is to find a way to use the world’s resources in a more sustainable manner… perhaps by eating bugs.

Entomophagy (i.e. the practice of eating edible insects) has many benefits (pdf) for the environment and people’s health: they have a better feed-to-meat ratio than conventional meat sources, emit less greenhouse gases, take up less space to raise, require little water, and contain high levels of protein, good fats, iron, calcium, and zinc. Overall, farming insects as miniature livestock is a smarter, more efficient and ultimately environmentally safer means of sustaining a healthy and convenient food supply.

More than 2 billion people worldwide supplement their daily diets with insects, so why can’t we do it too? The main obstacle to the consumption of insects in the Western world is the "yuck factor" involved in it; people are not used to seeing animal food sources in their entirety, and insects are generally seen as creepy crawlers that are dirty and unappetizing.

Nevertheless, the Dutch supermarket chain Jumbo has decided to add bugs onto its shelves from January 2015 onwards, in an attempt to gradually incorporate it into the Western diet. Their "Buggy burgers" and "Buggy Balls" (article in Dutch) will consist of only 6-10% bug parts, and may thus be the solution to our problem; gradually start introducing small amounts of bug produce into our diets to get over the yuck barrier. After all, disgust, like culture, is passed down from generation to generation, and it is never too late to start making a change. We did it with sushi, so why can’t we do it with bugs?

Bottom Line: We don’t need to start eating crickets for lunch every day, but a gradual change in attitudes towards incorporating bugs into our diets can lead to a significant reduction in the threat of food shortage the world is expected to face in the future.
