Scientists Have Calculated That in 30 Years the Number of Insects Has Decreased by 25%
According to a global study, the number of insects has decreased by almost 25% since 1990. The mass extinction of insects in Europe has been particularly shocking.
Insects are the most numerous creatures together with spiders and crustaceans in their mass and they are 17 times superior to mankind. Insects are vital to ecosystems. They pollinate plants, provide food for other creatures, and process dead plants
Scientists at the German Centre for Integrative Biodiversity Research in Leipzig have conducted 166 studies in 1,700 habitats.
The massive decrease in the number of flying insects was a real ecological disaster. Increased carbon dioxide levels are reducing plant nutrients and significantly reducing the number of species.
Urban expansion has been found to be harmful to insects because each area used to be their habitat. This has been particularly rapid in East Asia and Africa.
Insect losses are also caused by pesticides and light pollution. Increases in temperature and precipitation can harm some species, contributing to the increase of other insects in the same area.
For example, the number of freshwater insects increases by 11% each decade after cleaning up contaminated water bodies. But this group represents only 10% of insect species and does not pollinate crops.
