The U.N. recently released a report extolling the virtues of edible insects as an environmentally responsible alternative to meat as a source of protein and other nutrients. With their high fat, protein, fiber, and mineral contents, edible insects certainly pack a healthy punch! What's even better is that the cost to our environment to raise insects for consumption is far less than the impact of raising large livestock for meat.
Even though entomophagy, or the act of eating insects, hasn't quite caught on in the West (yet!), in many other countries around the world, bugs are eaten with gusto and are often considered a delicacy. So, why should you add bugs to your menu?
The Problem: Meat is Unsustainable Relying on large livestock (cattle, pigs, and chickens, for example) for one's primary source of protein means one must rely on highly inefficient, greenhouse-gas-producing, and sometimes cruel practices to obtain nutrients. Not to mention the health problems associated with consuming too much meat. With the world's population growing at an incredible rate and the demand for food rising along with it, having enough land to support both people and large livestock will soon become an issue, as well. All this is why many have said that producing and consuming as much livestock as we do is not sustainable.
But, you're not willing to go cold turkey on your meat and go vegetarian? Why not try substituting meat with insects every now and then? All the nutrients, none of the burden on our environment.
Edible Insects: Less is More Insects are an eco-friendly food option for a simple reason: they need less -less food (some insects can be raised on human/animal waste, which reduces the possibility of environmental contamination and avoids wasting food that could be eaten by humans), less water, less space. They even release fewer greenhouse gases and ammonia than cows, pigs, and chickens.
Many insects' feed conversion rates (the amount of feed it takes to put on 1 kg (2.2 lbs) of body weight in an animal) are much lower than traditional meat sources. The feed conversion rates of crickets, chickens, pigs, and cows are shown below:| Crickets | 3.7 lbs of feed: 2.2 lbs of body weight gain |
| Chickens | 5.5 lbs of feed: 2.2 lbs of body weight gain |
| Pigs | 11 lbs of feed: 2.2 lbs of body weight gain |
| Cows | 22 lbs of feed: 2.2 lbs of body weight gain |
Large livestock create a larger toll on the earth with problems ranging from habitat destruction, loss of biodiversity, greenhouse gas emissions, and contamination from livestock and feed farms and farming practices. In general, insects are more efficient to farm and their impact on the environment is much less severe.
For something we spend so much time and money trying to exterminate, insects may actually be the first step to a solution to many of our world's burgeoning social and environmental problems. All we have to do is get past those legs.
