The United Nations Reports That 1 Million Species Are On The Verge Of Extinction
The world's top scientists are conducting the most thorough health check on the planet, the only planet that is currently found to be alive. In announcing the results of the inspection, scientists warned that the Earth's natural life support system is accelerating recession and that human society is at risk.
According to the global life assessment report released by the United Nations, from the flashing coral reefs on the sea floor to the rainforests that have dried up into the prairie, nature is destroyed dozens to hundreds of times faster than the average speed of the past 10 million years.
According to the study, the biomass of wild mammals has fallen by 82%, the natural ecosystem has lost about half of its area, and 1 million species are at risk of extinction. Scientists believe that all of this is largely the result of human action.
The study was compiled by more than 450 scientists and diplomats in more than three years.
Two-fifths of amphibians are at risk of extinction, and one-third of corals and nearly one-third of other marine species are also at risk of extinction. The situation of insects is still unclear, but conservative estimates suggest that at least one in ten insects are threatened with extinction, and in some areas the population has collapsed.
From an economic point of view, the loss of species is staggering. Losses caused by the disruption of pollen transmission in plants have threatened crop yields of up to $577 billion (about 3.9 trillion yuan), and land degradation has reduced global productivity.
The report says the chain effects on human survival, including freshwater shortages and climate instability. This is already an "ominous sign", and this effect will be even more serious if strict remedies are not taken.
“The health of the ecosystems we and other species depend on is deteriorating faster than ever and is eroding the foundations of the world economy, livelihoods, food security, health and quality of life.” Global Biodiversity and Robert Watson, chairman of the Intergovernmental Science Policy Platform for Ecosystem Services (IBPES), said. "We have lost some time, so we must take action now."
The commentary said that a warning issued by a UN report showed that the situation was extremely serious because the report must be unanimously agreed by all countries. Hundreds of scientists compiled 15,000 related academic research and reports. They are based on the 2005 Millennium Ecosystem and go one step further, focusing not only on the list of species, but also on the networks of interactions between biodiversity, climate and human well-being.
Over the past week, representatives of governments around the world have fine-tuned summaries for decision makers, including remediation options: government “changes” in all areas, revision of trade rules, large-scale investments in forests and other green infrastructure, and Changes in personal behavior, such as reductions in meat and material consumption.
In recent months, the United States and Spain have held a green New Deal debate, and the United Kingdom has erupted a large-scale protest against environmental damage. The crisis caused by global climate change is getting closer.
The two main authors of the UN report hope that the 1800-page Biodiversity Assessment Report will bring the natural crisis to the focus of global attention, just as the United Nations Intergovernmental Panel on Climate Change (IPCC) released the Earth's temperature last year. Since the 1.5-degree warning report will be raised, the climate collapse has risen to the same on the political agenda.
David Obura, one of the lead authors of the report and the global authority on coral research, said: "We are trying to prove how much we will concentrate if we invest heavily in transformative behavioral changes. People’s attention, but at the same time, it’s not too late. Survival is the root of humanity. We are talking about not just species, but our life-sustaining system.”
This report shows that on this planet, the human footprint is so large that there is almost no room left for anything else. Three-quarters of the land has become farmland, covered by concrete, engulfed by dam reservoirs, or undergoing major changes. Two-thirds of the marine environment is also changing due to fish farms, shipping routes, sea mines and other projects. Three-quarters of rivers and lakes are used to grow crops or livestock. As a result, more than 500,000 species do not have enough long-term habitats, many of which will disappear within a few decades.
