To reduce environmentally unfriendly meat production and to save fish stocks, eating insect-based products is a very real alternative and it is only in the Western world that it is seen as unusual and is uncommon. Over two billion people around the world already eat crickets and they are considered a delicacy in Africa, Asia and South America.
According to the UN Food and Agriculture Organization, farming insects produces one hundredth of the carbon emissions of the equivalent output from beef cattle or pigs and they require less resources when farmed.
Crickets produce less than 0.1% of emissions than cows, only need 20% of the water a cow requires to produce the same amount of protein, and can be farmed in almost any climate or environment.
If you want to help the environment, and are already making as many eco-friendly choices as you can, then eating crickets is another product to add to your shopping list.
