A little late, according to ecologists, humanity has set itself the task of preserving biological diversity in nature. As a result of cataclysms and illiterate human activities, many species of plants and animals disappeared from the face of the Earth. The question is possible: "So what? After all, there are still so many other species!"
Biodiversity on the planet is the presence on it of a large number of species of all kingdoms: animals, plants, mushrooms. The task of preserving them is one of the most important in ecology. Planet Earth is really rich, therefore man is obliged to protect this wealth at least so that it will be left to the next generations of people. So that grandchildren and great-grandchildren could see wonderful animals, beautiful corners of nature, could use medicinal plants. Any plant, animal (even the smallest) is part of a biogeocenosis, and in general, is included in the entire ecosystem of the Earth. The body is involved in the cycle of substances, being a link in the food chain. Producer plants synthesize nutrients using solar energy. Consumptions consume the energy accumulated by plants and other animals, deritophages "utilize" carrion, and reducers finally decompose nutrient residues. Thus, each organism occupies a specific place in nature and performs a specific role. The disappearance of one link can cause the disappearance of several more, changing the entire chain. Not only will the food chain become impoverished, but also the imbalance of species in the ecosystem. Some species may disproportionately increase in number and cause an environmental disaster. As, for example, an unprecedented breeding of locusts can deprive the crop of entire areas. Preserving the richness of species on the planet, we thus maintain the stability of ecosystems, ensure the safety of life of all species, including human life. In addition, scientists want to preserve the genetic information of each species, with the expectation of future technologies that will allow you to recreate the animal world of the past, for example, in isolated recreations (parks), to recreate extinct and extinct species of animals and plants.
