40% of the world’s insects are at risk of extinction
According to a scientific study on the number of earthworms, 40% of their species are declining rapidly worldwide.
The study warns that flies, ants and beetles are becoming extinct eight percent faster than birds, reptiles and mammals.
However, researchers say there is a possibility that some species, such as house flies and red bags, will increase in number. Excessive farming, use of pesticides and climate change will increase the number of earthworms. The reasons for the decrease are given.
Insects are a large part of the creatures found on the planet and give many important benefits to other creatures, including humans.
They provide food for birds, bats and small mammals, sow 75% of the world’s crops, fertilize the soil and control the number of pests in it.
Various studies in recent years have also shown that some individual species of insects, such as bees, are more susceptible to extinction, especially in developed countries.
However, the article under discussion sheds more light on this issue.
The study, published in the journal Biological Conservation, looked at 73 research articles from around the world over the past 13 years.
Researchers have found that 40 percent of the world’s insects will become extinct in the next few decades if the decline continues. According to him, one third of the world’s insects are in ‘danger’.
Dr Francisco Sanchez Beschio, head of the team of researchers at the University of Sydney, told the BBC: There is deforestation and increasing settlement in the cities.
“Second, the increasing use of chemical-rich pesticides and synthetic fertilizers in agriculture, third, a few biological factors such as invasive pathogens, and fourth, climate change, especially in the tropics, where they have a clear impact.” Some other experts also say that the study “needs serious consideration”.
“It’s not just about bees, spawning or our food,” says Matt Shardlow of the Big Life campaign in the UK. Insects found in dung that recycle it or large flies that start their lives in rivers and ponds are also becoming extinct.
“It is clear that life on Earth is in a state of disarray and that a concerted and global effort is needed to stop these harmful activities,” he said. It would not be wise to allow the gradual extinction of insects.
Increase in harmful insects
This article shows that although many species of insects are in decline, some species are able to adapt to changing conditions.
Dave Golson, a professor at the University of Sussex, says: “Hot humid climates will increase the number of fast-growing harmful insects as their natural enemies become extinct.” On the planet a small but very harmful insect remains but we get rid of all these beneficial insects such as flies, butterflies, whirlpools and insects found in dung, which destroy animal waste. will go.’
Professor Golson says some hardy and environmentally friendly insect species, such as house flies and red bags, will be able to survive more easily in the new environment because they have developed a defense system against harmful insects. has taken.
“Although the overall situation is disturbing, we can do this by not using pesticides and by using vegetables grown without the use of fertilizers to protect our garden from insects,” he added. Make a loss
More research is needed in this regard, as 99% of the evidence of declining insect populations comes from Europe and North America, while almost nothing comes from Africa and South America.
Professor Golson told that if you study the species that became extinct in the past, you would find that only those species that survived adapted to the needs of the new environment survived.
According to him, you give them thousands of years and I am sure that new species and types of insects will be born that will replace the endangered species in the 20th and 21st centuries.
