Can humanity survive without insects?

Have you thought about the meaning of being an ordinary mosquito? Or, for example, butterflies? Scientists are convinced that despite their seemingly completely meaningless existence, insects are a necessary link in the life chain of not only humans, but all life on our planet. According to experts, about 1 million species of animals and plants are already on the verge of extinction, and half of them are represented by insects, the death of which can have disastrous consequences for the entire flora and fauna of our planet.

According to some reports, the total biomass of insects fell by an average of 70% compared with 1994

What are insects for?

Despite all the “carelessness of being” butterflies ormosquito terrorizing us on summer nights, their simple existence in nature can be a vital component for human survival on a blue planet. From school, you may be aware that one of the most important and necessary functions that insects perform is pollination. Since about 80% of plants that need pollination with other living organisms live on our planet, insects easily take on this task. Many types of fruits and vegetables would simply not exist if the insects died out.

Besides fulfilling its main task,a number of insects are involved in decomposition processes, processing both leaves and trees in the forest, and the bodies of dead animals. Insects use the remaining nutrients in them, and then return them to nature again.

In other words, if in the modern worldif insects remained, humanity would not only face hunger, but would also have to come up with a technology for mass processing of corpses. So, due to the lack of many habitual reducing organisms, the bodies of dead animals would remain undecomposed for a long time. For example, insects can “decompose” the body of a dead elephant to the bones in the jungle in 2-3 days, and now imagine how many corpses could have been on the ground for a long time without their participation ...

Over the past year alone, about 30% of bees died in Russia due to the emergence of new pesticides

According to an article published on the siteSciencealert.com, the main reason for the current decline in insect numbers is the drastic depletion and degradation of the insect habitat due to the active use of pesticides and insecticides by humans. Chemicals poison and pollute not only feed, but also soil, causing a reduction in suitable habitats for most insects.

Mass extermination of butterflies, bugs, ants,bees, wasps, crickets, dragonflies and even flies have sad consequences far beyond their own destruction. Thus, the significant decrease in the total number of birds that is currently observed in Europe is directly related to the lack of food supply necessary for their existence.

Experts say that afterthe industrial era came into its own and began to be active about 200 years ago, about 5-10% of all types of insects have already died out. Such a fast pace of destruction of wildlife can lead to disastrous consequences for all of humanity, which directly depends on it.
