The number of virtually all insects has decreased by 75-82% in all reserves and national parks in Germany, the reason for which is not yet clear and the consequences of which can be extremely serious, ecologists say in an article published in PLoS One.
"All those corners of nature that we studied are nature reserves, whose territory is protected by law and the authorities of Germany. Despite this, in all of them the number of insects has dropped sharply. Perhaps this was due to the fact that they are all surrounded by agricultural land, where insects simply cannot survive, "said Caspar Hallmann of Radbud University, Germany.
In recent years, ecologists and biologists have become seriously concerned that the species diversity and abundance of many insects have begun to decline sharply in recent years.
For example, recent observations in Britain have shown that six species of the most common butterflies may disappear from the island in the coming years, and the prevalence and number of many species of wild bees in South America may decline sharply by the end of the century.
Hallmann and his colleagues found out that the scale of this ecological catastrophe is greatly underestimated today, having carried out a kind of "population census" in six dozen nature reserves created in Germany over the past century.
The countless number of insects living in every corner of the Earth makes it difficult to carry out such calculations directly, and therefore scientists carry out them by setting special traps in the territory of national parks and counting the number of insects that fall into them over a certain period of time.
Comparing the weight and number of individuals in such a "catch", one can understand how the species diversity and number of insects change over time.
Insect trap in the park
Such observations, Hallmann says, paint a disastrous picture in recent years. According to scientists, the number and biomass of insects has decreased by about 75% and 82% in all sixty reserves, despite the huge differences in climate, flora and fauna between them.
For example, in 1990, about 10 grams of insects fell into traps every day, and today this figure has decreased to 2 grams per day. This sharp drop, as the researchers note, could lead to the collapse of all ecosystems - it affected not only various predatory and parasitic insects, but also pollinators.
The reasons for this are not yet clear, however, German ecologists suggest that the decrease in the number of pollinators and other insects may be associated with the intensification of agriculture and the spread of herbicides, which reduce biodiversity among plants and limit the distribution paths of invertebrate inhabitants of forests and meadows that feed on their leaves, wood and pollen.

Judging by the reviews of friends and neighbors, Michael and Camden were happy with each other and there was no disagreement between them. On the evening of November 7, 1997, he

A heavy and not small ecological monitoring station disappeared from the German part of the Baltic Sea. It was installed at the bottom and where it disappeared until both the police and the owners of the station can understand. According to the BBC, this station was called the "marine observatory" because of its advancedness and it costs 300 thousand euros and weighs 770 kg (Paranormal news - paranormal-news.ru). "It was impossible to drag her away by storms or large animals," German experts say. Station stood

A Third Of Insects Have Disappeared In Germany Over The Past 10 Years
Scientists have studied more than a million insects in the forests and meadows of Germany and found that their number decreased in the first case by 40%, and in the second by a third. And all this in just 10 years. Scientists are frightening with forecasts that at such a pace both Germany itself and our planet as a whole will have very unpleasant consequences in the not too distant future. Insects make up two-thirds of all species on Earth and they participate in a huge number of important life-forming processes. Fundamental research on insects has been carried out by me
