Insect protein is a much-discussed alternative to meat, dairy and eggs because it can be raised cheaply and sustainably.
Raising insects will ultimately slow the environmental degradation process. Crickets, for example, are so much more sustainable as a protein than beef. A single cow can produce up to 132 pounds of methane a day which is roughly equivalent to a car. A cricket, however, produces 80 times less methane than a cow.
