Farming insects may solve one problem but create others, Swedish scientists warn
There is currently an “overwhelming lack of knowledge” on basic questions such as suitable species, their housing and feed requirements, managing their waste and that escaping insects do not wreak havoc on the ecosystem, they said.
Unless such issues are studied and discussed in a critical manner, “we risk creating an industry that replaces one environmental problem with another,” they wrote in the journal Trends in Ecology & Evolution.
Globally, growing demand for animal protein has led to expanded cultivation of soybeans to feed livestock and poultry, but critics say the system is unsustainable and leads to deforestation and overuse of farm chemicals.
Nutritionists and scientists have been touting insects as sustainable and cheap source of protein to feed a growing world because they are high in protein, vitamins, fiber and minerals.
