Man was the cause of a new extinction. What to do

Человек стал причиной нового вымирания. Что делать

The sixth wave of extinction began with human

Because of the human impact on the environment about a million species of animals and plants on the verge of extinction.

Established UN intergovernmental science-policy platform on biodiversity and ecosystem services IPBES issued a report which States that due to human impact on the environment about a million species of animals and plants on the verge of extinction.

The level of extinction of wildlife today in tens, if not hundreds of times higher than in the last ten million years and the pace has only accelerated. Last year scientists say about the beginning of the sixth wave of mass extinction.

But ways to correct the situation known. It is primarily about the fight against warming and the reduction of all kinds of impurities, particularly amounts of plastic waste. It will also entail the immediate improvement of the living conditions of the population. Корреспондент.net tells details.

 

The collapse of biodiversity

65 million years ago extinct 75% of animals inhabiting the Earth, most of which were dinosaurs. Previous extinction was 95 percent of all animals and plants.

Scientists believe that the planet began the sixth wave of mass extinction, but the first, which occurs due to one particular type of person.

New extinction may not occur in the scale of geological time, and in just a few decades. The level of extinction of wildlife today in tens, if not hundreds of times higher and continues to accelerate, the report said.

About a quarter of species are threatened with extinction in most parts of the studied groups of animals and plants. Almost half – 47 percent – natural systems disappeared. The global biomass of wild mammals declined by 82 percent.

Human activities that Deplete biodiversity:

  • the destruction and fragmentation of natural habitats;
  • the lack of attention to the long-term consequences of actions that destroy the conditions of existence of living organisms in the oceans and the forests, exploiting natural resources;
  • climate change;
  • environmental pollution;
  • pollution of ecosystems, waste, pesticides, and plastics;
  • the introduction of alien species, and plant international trade.

In 2020, China will host a conference on biodiversity. It should be adopted specific commitments that will be reflected in public policy and to attract economic players and civil society.

The ozone hole will disappear by 2060. That helped

Extreme measures at the political level to prevent global ecological disaster, warn the working report of the experts from 50 countries.

“Our report focuses on how quickly we are losing biological diversity and the extent to which we are able to maintain it in the future. If we want our children to leave the world, not destroyed by man, we must act immediately,” said the IPBES chair Professor sir Bob Watson.

How to save the biosphere

1. Protivodejstvie to the disappearance of natural systems on land and in water. Three-quarters of the Earth’s surface, including water, has undergone a major change due to human activities. This was, as stated in the report, the main cause of biodiversity reduction.

To prevent this, scientists propose 17 percent of land and 10 percent of oceans to turn into the protected area – parks.

You also need to make agriculture environmentally friendly, that is, one that is consistent with the needs of the environment.

Meat from the tube and insects. Food of the future close

The report States that the need to protect indigenous peoples, who are the “guardians of nature”. Their future threatened by mining projects and deforestation.

2. To deal with excessive fishing and poaching. One-third of the world’s fish reserves are being exploited at an excessive level, and 60 percent of the remaining numbers is maximum. Fish do not have time to reach maturity and reproduce. It is necessary to reduce the catch of bluefin tuna, stone bass and hake.

Japan recently decided to resume commercial whaling. And in Africa poachers continue to destroy the population of rhinos and elephants.

3. To combat global warming. The world’s average temperature has already risen about a degree since the industrial era that was a blow to the most fragile ecosystems and has pushed many species to migrate to more temperate latitudes.

But to find a new home are not all animals. So, as a result of climate change extinct reef mozaichist rat, becoming the first victim of global warming.

4. To reduce all types of pollution. Despite progress in some regions of the world, other pollution continues to worsen, leading to tragic consequences for the environment.

Thus, the volume of plastic waste in the oceans has increased tenfold since 1980-ies, which has a negative impact on the lives of many types: 86% of sea turtles, 44% of seabirds and 43 percent of marine mammals.

In the world’s oceans every year gets 300-400 million tons of heavy metals, chemical solvents, toxic wastes, the report said.

Plastic-killer: how the world refuses to tubes

The release of fertilizer covers 245 thousand square kilometers of coastal zones and leads to the formation of oxygen-poor areas with excessive number of invasive algae.

Decisions relate both to changes in habits (for example, reducing the use of plastic bags), and the development of regulations and infrastructure, in particular wastewater treatment, collection and recycling.

5. To reduce the appearance of exotic invasive species. Louisiana cancer, the Asian hornet and bullfrog are among the 37 species that were recorded in this category the European Union.

Human activities destroyed their geographic and ecological boundaries, and they went to look for other conditions for life, displacing or destroying the weaker species in a new location.

Invasive animals pose a risk for almost one-third of all endangered species and is involved in half of the known cases. The number of problematic EEV increased by 40 percent since 1980.
