Climate-endangered animals play an indispensable role in ecosystems

According to UN estimates, by 2050, nearly 1 million animal species will die out on Earth, including a huge number

insects. Already, 75% of land, 40% of the ocean and 50% of river waters "demonstrate degradation due to human activities."

This is mainly due to greenhouse emissions.gases. According to the organization, since 1980 the level of anthropogenic emissions has doubled - this has led to an increase in the average temperature on Earth of at least 0.7 ° C.

Researchers have calculated the features of the impact onecosystems of all living birds and mammals on the basis of six characteristics - body weight, litter size, intergenerational difference, habitat width, type of diet, and dietary diversity. This allowed them to identify the most distinct species from others and combine this data with information from the Red Book of species that are threatened with extinction.

Work has shown that mammals such asthe Asian elephant and the Sumatran rhino, and birds such as the bustard, Amsterdam albatross and the Somali ostrich, are threatened and are very different from each other from an environmental point of view. Thus, the extinction of these species may lead to the loss of unique ecological roles.

These roles are very diverse: herbivores, such as elephants and hippos, can affect the structure of vegetation and the nutrient cycle, and predators - white-tailed eagle, leopard, gray wolf and cougar - can prevent overgrazing, increase productivity and limit the spread of diseases.

Avoiding Pesticides and Creating Insect Preserves will allow slow down their extinction. These and seven other steps, an international group of researchers from 30 countries proposed as measures to prevent the global extinction of insects, which can lead to many adverse consequences.
