Insects and spiders rapidly disappear from the face of the Earth. Than it threatens?

the disappearance of the insects recorded worldwide. And it's very bad
Even if you don't like and are afraid of spiders, to enjoy their disappearance is not worth it. According to the results of the research, the number of insects and spiders reduced in forests and grasslands throughout Germany. The scientists described their findings as "alarming", stating that the loss caused by the intensive development of agriculture. The researchers call for "a paradigm shift" in the politics of land use, to preserve the habitat of the butterflies, beetles and other flying insects. A recent analysis published in the , confirms that some species of insects on the path of extinction. But why is it bad for our planet?
Humanity is threatened of extinction a million types
A Number of recent studies have revealed the disappearance of insect populations around the world. According to Dr. Sebastian Seybold from the Technical University of Munich in Freising , it becomes clearer and clearer that the causes of decline are associated with the practice of agriculture. "Our study confirms that the reduction in the number of insects is real — it may be more common than previously thought, given, for example, that in the forests are also experiencing declining numbers of insects," — told the scientist in an interview .
The Researchers note that this reduction occurs not only in the areas with intensive management of agriculture, but also in protected areas — so the areas that, according to scientists, protect biodiversity, be useless. Recall that earlier this year was published by the intergovernmental science-policy platform on biodiversity and ecosystems (IPBES) on the state . According to the findings of researchers, the mankind has threatened the extinction of a million species of animals. Some experts do not hide their pessimistic attitude and call what is happening with wildlife “sixth mass extinction”. And the results of recent studies show a reduction in diversity of butterflies.
What happens if the insects were to disappear?
The Research team recorded data about more than a million individual insects and spiders (2700 different species) on hundreds grasslands and forest lands in three regions of Germany in the period from 2008 to 2017. In the course of work the researchers found that a significant reduction in the number and quantity of species like meadows and forests, with the main factors (at least for meadows), due to the intensive development of agriculture and increase lands destined for agricultural purposes.

In the future, the diversity of butterflies is greatly reduced
Many other studies in recent years have shown that some species , such as bees, have suffered greatly, especially in developed countries. Scientists say that one of the main reasons for the disappearance of bees is the pesticides that are sprayed many fields and meadows around the world. However, some species of insects such as flies and cockroaches, apparently, are on the rise. Agree, it's a red flag, because cockroaches and flies are the carriers of infections. And the further disappearance of the insect populations will inevitably lead to the emergence of a huge number of pests.
The Destruction of insects has far-reaching consequences for entire ecosystems, experts warn. Not so long ago we told you that a number of recent studies have revealed that the contamination of soil by earthworms makes microplastics to lose weight. A reduction in the number of insects associated with intensive farming, pesticides and climate change. Together, these factors threaten the overall health of ecosystems. Thus, the picture emerges of the future is pretty grim. And first of all, because insects are a food source for many birds, amphibians, bats and reptiles, not to mention the plants that rely for pollination on the insects.
