World’s insect population under threat due to climate change

Another study found that forest-dependent orchid bees in Brazil have also declined by around 50% , according to a report in NewsDay.

A 2021 study had revealed that there has been a 30-50% decline in the butterfly population across Europe. Butterflies are not just pleasant to the eyes, but also play an important role in the functioning of an ecosystem.

The majority of the world’s estimated 5.5 million insect species are thought to live in the tropics, including countries like Brazil, India and Africa. The fast-emerging threat to insect biodiversity has been attributed to rising temperatures and increasing frequency of extreme weather events.

The study also suggests ways to tackle the problem. It says that lowering the use of chemicals in farming and having a greater diversity of crops can mitigate some of the effects of climate change. It also highlighted how important it is to preserve the natural habitats of insects if we wish to help them survive.
