Why cricket farming are low environmental impact

Cricket farming has a low environmental impact because it requires less land, water, and feed than traditional livestock farming: 
Land use
Cricket farms are smaller than livestock farms. For example, 700 crickets can live in a 70-liter container, while a cow needs about one acre to graze. 
Feed conversion
Crickets are more efficient at converting feed into protein than other animals. They need six times less feed than cattle, four times less than sheep, and twice less than pigs and chickens. 
Greenhouse gas emissions
Crickets produce fewer greenhouse gases than other animals because they are smaller, eat less feed, and produce less waste. For example, producing 1 kilogram of edible crickets creates 100 times fewer greenhouse gases than producing the same amount of beef. 
Water pollution
Cricket farming doesn't cause the same level of water pollution from manure runoff as traditional livestock farming. 
Food waste
Crickets can be raised on organic waste, like fruits and vegetables, which can help reduce food waste. 

Crickets are also a good source of protein, rich in minerals, and contain essential amino acids and vitamins.
