Lovely Grub: Are Insects the Future of Food?
“I believe you’re the first human being on the planet to have ever been served anything cooked with this,” Reade tells me. But not to worry: “I’ve eaten some of it myself, an hour ago. I’m still alive.”
I inspect my plate.
Reade urges us to begin: “Eat before it gets cold.”
The next morning, Reade and Evans join 450 of the world’s foremost experts on entomophagy, or insect-eating, at a hotel down the road in Ede. They are here for Insects to Feed the World, a three-day conference to “promote the use of insects as human food and as animal feed in assuring food security”.
The attendees are all familiar with the same dire facts. By the year 2050, the planet will be packed with 9 billion people. In low- and middle-income countries, the demand for animal products is rising sharply as economies and incomes grow; in the next few decades, we’ll need to figure out how to produce enough protein for billions more mouths. Simply ramping up our current system is not really a solution. The global livestock industry already takes an enormous toll on the environment. It’s a hungry and thirsty beast, gobbling up land and water. It’s a potent polluter, thanks to the animal waste and veterinary medicines that seep into soil and water. And it emits more greenhouse gases than planes, trains, and automobiles combined.
The insect authorities assembled in Ede believe that entomophagy could be an elegant solution to many of these problems. Insects are chock-full of protein and rich in essential micronutrients, such as iron and zinc. They don’t need as much space as livestock, emit lower levels of greenhouse gases, and have a sky-high feed conversion rate: a single kilogram of feed yields 12 times more edible cricket protein than beef protein. Some species of insects are drought resistant and may require less water than cows, pigs, or poultry.
