While it is true that insects may offer significantly better feed-conversion ratios and a smaller land-use footprint compared to traditional livestock systems, this does not guarantee that the insects-as-food industry will be environmentally friendly.

Meat producers have a new animal to farm. In an effort to be more
sustainable, the industry is turning to insects as an alternative
source of protein. But new research on insect sensitivity and
behavior raises ethical questions about this surprising trend.
Humans have fed on insects for centuries and continue to do so
today. According to the Food and Agriculture Organization of the
United Nations, in 2013, insects were still part of the traditional
diet of at least two billion people around the world, mostly in
Africa, Latin America, and Asia. Most of the small six-legged land
animals consumed for food today are collected from the wild.
However, in some countries, insect farms have existed for several
decades.
Such is the case in Thailand, where experts estimate there are
20,000 small- to medium-scale cricket farms and about 5,000 for palm
weevil larvae, and in China, where there are even some
industrial-scale cockroach farms intended mainly for the production
of medicines and animal feed. Cambodia, the Lao People’s Democratic
Republic, the Democratic Republic of the Congo (DRC), and Kenya also
have insect farms, mostly for crickets. Most of these farms are
small-scale and not technologically developed.
