What would happen if all the insects on earth disappearedBy Vika https://pictolic.com/en/article/what-would-happen-if-all-the-insects-on-earth-disappeared
According to recent scientific studies, the number of insects is decreasing at an alarming rate, and this could lead to the extinction of 40% of the species in the next decades. It may have occurred to you that the planet would be better off without them, but the truth is, their disappearance would cause chaos in the environment and nutrition.
We would like to tell you about the importance that these animal species have for the ecosystem and the impact that their extinction could have.
1. Without bees, flowers, and food will disappear.
Environmental charity Earthwatch has declared bees "the most important living thing on the planet." In addition to being honey producers, they are the main pollinators of the animal kingdom, the cornerstone of the natural process that allows the production of seeds and fruits. Without this transport of pollen, the world's agricultural production would decrease by 30% and flowering plants would disappear by 90%.
2. Cockroaches play a key role in the nitrogen cycle.
Away from cities, cockroaches are a food source for small mammals, birds, and reptiles. In addition, they consume decaying matter, and the excrement they leave behind is filled with nitrogen, an essential element for plant growth. Thus, without these insects, an imbalance will be created in the ecosystem, both in the animal and plant world.
3. Ants carry seeds and increase biodiversity.
Although there are over 14,000 species of ants with very different characteristics, some of them carry seeds that fall from plants to the ground. Others play a role in pollination. They are also food for several species, including the famous anteater and even humans in some cultures.
4. A world without flies is a world without chocolate.
If flies were destroyed, then only bacteria and fungi would consume and destroy animal carcasses, and this process would take much longer. They are also essential for the processing of feces, and some species are active pollinators. For example, ceratogonids are important pollinators for tropical crops such as cocoa, which allows the chocolate to survive.
5. Beetles are natural processors.
For example, the ladybug feeds on aphids and helps control this insect that attacks crops. Coprophages also play a fundamental role: they are the largest processors of manure.
6. Crickets indicate soil health and are a nutritious food.
There are several reasons why these orthopterans should not disappear: they are a source of food for birds, reptiles, and even humans. Chapulins are a Mexican dish that is high in protein and low in fat. On the other hand, these species indicate the health and biodiversity of land with pastures.
7. Spiders are effective predators against plant pests.
Most of the species that live with humans are not dangerous or aggressive. They live in habitats where there is life, and they are important to the ecosystem, mainly as predators. They prey on flies and mosquitoes, which in some cases carry disease.
