According to a new UN survey, people are dramatically changing the natural landscape of the Earth to the extent that 1 million plants and animal species are now on the verge of extinction. The upcoming crisis also threatens people as these species are important for their survival.
The report of 1500 pages shows, according to scientific sources, the magnitude of biodiversity loss on our planet and the risks faced by humans. With the human population surpassing 7 billion, activities such as farming, fishing and mining, change the landscape of nature altogether.
At the same time, another threat is a fact: global warming has a negative impact on the survival of wildlife. In the way climate changes, mammals, birds, insects, fish and plants are increasingly struggling to adapt and survive. Combined with additional human actions that harm the environment, more and more animals tend to disappear.
As a result, biodiversity is expected to decline more rapidly to 2050, especially if certain countries do not make drastic changes.
This is not the first time that a survey outlines the future of Europe's ecosystems in the most ugly way.
People produce more food than ever before, but land impoverishment affects agricultural production to the extent of 23% of the planet's field. Reducing wild bees as well as other fruit and vegetable pollinators raises 577 billion dollars in annual production at risk. At the same time, the loss of long-lived forests and coral reefs along the coast could expose up to 300 to millions of people at increased flood risk.
Although scientists have only registered one part of living beings, about 1.3 million, research estimates that there are about 8 million plants and animals on the planet. Most of these are insects. From 1500, at least 680 items have disappeared.
Scientists may not be able to give specific predictions, but the report warns of a large extinction crisis. Its speed is expected to be 10 with 100 times bigger than that of the last 10 million years
"Human actions threaten more endangered species than ever before," the report concludes, "about 1 million species face extinction, many of them in the next few decades unless the necessary actions are taken."
Altogether, three quarters of the surface of the earth has been radically transformed after human interventions.
As people continue to burn fossil fuels for energy, global warming is expected to burden the disaster. Almost 5% of species is threatened with extinction for climate change reasons if the average temperature rises to 2 degrees Celsius in the post-industrial era (the temperature has already risen to 1 grade).
The number of threatened species will not make our planet simply less colorful and beautiful, but it is a great risk to humanity.
Today, people rely heavily on plant and animal varieties to produce food. Among the 6,190 domesticated mammalian species used in agriculture, over 559 have disappeared and 1000 are threatened. This means that the nutritional system becomes less resistant against parasites and diseases.
But according to the survey, there is hope. When governments have been forced to protect certain species, they have succeeded. Although at the moment only a small part of biodiversity is protected and many parts of the world face the problem of poaching, harvesting and illegal fishing.
Therefore, as the change is global, growers and ranch owners will have to adopt new techniques to grow more food on smaller plots. At the same time, citizens of wealthy countries will have to eat less food and be better served than natural resources. Governments in all countries should strengthen environmental laws to limit illegal logging and fishing.
According to the authors of the survey, efforts to limit global warming will be critical, as diplomats from all over the world will do various things over the next two years meeting in the framework of the "convention on Biological diversity"To discuss their efforts to protect it. In the most optimistic scenario of research, until 2050, the world's states will only slow the decline in biodiversity - they will not stop it.
