Researchers from Wageningen University in the Netherlands say that insects produce far less greenhouse gases than cattle and pigs do, and would thus be a viable alternative to eating meat. Published in the journal PLoS ONE, the study found that pigs, for instance, produce up to one hundred times more greenhouse gases than the equivalent weight of mealworms.
Researchers compared the greenhouse gas emissions of mealworms, crickets, locusts and pigs. Particularly with methane (CH4) and nitrous oxide (N2O), the insects produced far lower emissions than pigs did overall. Ammonia emissions, which can pollute groundwater supplies, were also lower among insects compared to cattle.
Researchers did not verify that actually producing insect protein for human consumption is as environmentally-friendly as producing cattle and pig protein, pound for pound. So while the idea may sound beneficial in theory, it is unknown whether or not it would work in real life.
