The flying insect population in Britain has fallen by almost 60 percent since 2004. This is the result of a survey reported by the server of the newspaper The Guardian, in which volunteers counted individual insects on car license plates last summer.
According to scientists, the survey needs to be repeated several times to make the numbers more reliable. However, the results already correspond to data on insect declines in other countries.
Results from many thousands of car journeys in Britain show a decrease of 65 percent in England, 55 percent in Wales and 28 percent in Scotland. Although scientists have so far organized only two such public surveys, and it is therefore possible that these were exceptionally good or bad years for insects, surveys in other European countries have yielded similar results.Read also Paleontologists in Patagonia have discovered the largest megaraptor to date
For example, a Danish study, based on data from 1997 to 2017, shows a decrease in the population of flying insects in the Danish countryside by up to 80 percent, due to agricultural pesticides and fertilizers.
Insects are key to a healthy environment because they recycle organic matter, pollinate plants and keep pests under control. Intensive agriculture and global warming are responsible for its decline, according to a recent study by the University of London UCL, which the server reported.Read also The giant penguin could become extinct in 30 to 40 years, scientists warn
“For the sake of the health and well-being of future generations, we can no longer delay the solution. It is absolutely essential that we stop the decline of biodiversity. It requires a political and social response, “Matt Shardlow of Buglife told The Guardian. She co-organized British research.
Buglife also said that in addition to the response of governments and town halls, everyone can help by growing longer grass in their garden and sowing meadows and wildflowers. “If each garden had a small area for insects, together they would probably form the largest natural environment in the world,” the organization said.
