Dear MEL Topic Readers,
China may send ducks to battle Pakistan's
locust swarms
As said in Vol.2860 on February 9th,
grasshoppers are usually solitary and harmless to humans. However, under
certain circumstances, they change their behavior and habits and become more
abundant, gregarious, and nomadic, called locusts. Although an adult locust
eats its own weight in food daily, or about one half of a gram, when they
become gregarious, they eat more and travel over 100 kilometers in a day and
eat anything they find on the way.
Now, locusts have invaded and devastated in
Pakistan, causing the worst infestation in two decades. One of its neighbors, China,
which has been busy fighting coronavirus for two months, is trying to give Pakistan
their hands to combat the locust swarms. This time, not with high-tech machines
like drones or artificial pesticides but with a natural predator, ducks. They
eat over 200 locusts a day, three times more than chickens do. Furthermore,
they’ll provide eggs and meat when they retire from their jobs. Sounds like a win-win
solution, doesn’t it?
Enjoy reading the article and think if humans
can make use of the natural food chain to solve a problem in nature.
