Experts say that if food were a country, it would rank second
behind the US as one of the biggest greenhouse gas polluters. The reason is the
rising demand for meat. Animal farming is responsible for 14.5 percent of
global methane emissions. While cows are the worst contributors, pigs, sheep,
donkeys and other animals play a part as well.
Animal agriculture also causes land to become damaged, water to be
polluted and forests to get destroyed. With the world population forecast to
rise to 9.8 billion by 2050, things are only looking worse for our already
decreasing natural resources. While going vegetarian would help, meat
consumption is too deep-rooted in most Western diets to allow for such a sharp,
permanent change. That is why experts are advocating substituting some of the
beef, chicken, or pork with ordinary insects!
Insects, which grow into adults within a matter of months, if not
weeks, are ready for consumption much faster than domestic animals. They also
require much less room, use less water and food, and produce far less
greenhouse gas than animals.
Of the 1.1 million insect species worldwide, scientists have
identified 1,700 as eatable. Among them are ants, grasshoppers, grubs, and
earthworms. Just like animals, each insect has a different taste. Tree worms
taste just like pork, and grubs are similar to smoked meat.
While eating insects might be a new concept for Western people, over 2 billion people worldwide consume insects as a regular part of their diet. Besides being delicious, insects are high in protein, have very few calories, and are free of the saturated fat found in animal meat. Insects can be prepared in many ways. Creative cooks can use them to cook protein-rich soup, make baked treats, and even fry a few with vegetables. So eat insects— both your body and Mother Earth will thank you for it!
