Scientists condemn the world’s insects to reduce 1,000 deaths



The world’s top insect experts say that the world’s important insect kingdom is “a thousand cuts.”

University of Connecticut entomologist David Wagner (David Wagner) said that climate change, pesticides, herbicides, light pollution, invasive species, and changes in agriculture and land use are causing the planet to lose about 1% to 2% of insects every year.12 studies in the Proceedings of the National Academy of Sciences Written by 56 scientists from all over the world.

This problem is sometimes called the insect apocalypse, and it̵

7;s like a jigsaw puzzle. Scientists say that they have not mastered everything, so they have difficulty grasping its hugeness and complexity, and cannot get the world to pay attention and do something.

Wagner said that scientists need to figure out whether the loss rate of insects is greater than that of other species. He added: “There are more reasons to worry because they are targets of insecticides, herbicides and light pollution.”

May Berenbaum, co-author of an entomologist at the University of Illinois and winner of the National Science Award, said: “The decline of insects was comparable to climate change 30 years ago because it is difficult to assess the degree and loss rate. ”

She said that to make the situation worse, in many cases, people hate bugs, even if they pollinate the world’s food, they are vital to the food chain and to eliminate waste.

Wagner said that insects are “absolutely the foundation of the mother nature and the tree of life.”

Two well-known bees and the monarch He said that the butterfly is the best indicator of the problems and decline of insects.The number of bees has dropped sharply Because of diseases, parasites, pesticides, herbicides and insufficient food.

Wagner said that in the western United States, the dry weather caused by climate change means that butterflies eat less milkweed. Changes in American agriculture eliminated the weeds and flowers needed for nectar.

He said: “We are creating a huge biological desert in a vast area of ​​the Midwest, except for soybeans and corn.”

Monday’s scientific paper did not provide new data, but a large and incomplete picture showing a problem began to attract attention. Berenbaum said that scientists have identified 1 million species of insects, and there are still about 4 million species yet to be discovered.

Doug Tallamy, an entomologist at the University of Delaware, was not part of the research. He said these studies highlight how the world “has spent the past 30 years, spending billions of dollars in finding new insect-killing agents. Methods, and just pennies to study them.”

Tarami said in an email: “The good news is that apart from climate change, people can do a lot to reverse the decline in insect populations.” “This is a global problem with grassroots solutions.”
