one million animal, plant species face extinction - un  -  carbon dioxide absorbent
Human beings are rapidly destroying the natural world on which we thrive.
Ultimately, our survival.
Depending on the United Nations landmark assessment of the state of nature.
Changes brought about by deforestation and pollution of forests, oceans, soil and air for decades "at least as much as climate change" threaten society, says Robert Watson, who has presided over 132-
The National Conference validated the summary developed by 450 experts for decision makers.
They reported that many people in the past few decades.
What is worrying is the accelerated pace of unique life --
Form is disappearing.
It's been dozens to hundreds of times faster than in the past 10 million years.

66 million years ago, birds and dinosaurs were extinct.
Joseph setter, professor at Helmholtz Center for Environmental Studies in Germany, said that in the short term, humans are not in danger.

"It's hard to say in the long run," he said . ".
"If human beings are really extinct, they will naturally find their way out. it is always like this.
Blocking and reversing these terrible trends requires "change "--
The report concluded that a comprehensive reform of the way we produce and consume almost everything, especially food.
"We are eroding the foundations of our economy, our livelihoods, our food security, our health and our quality --of-
"Life around the world," said Mr. Watson.
"The so-called change, we are referring to a fundamental system --
Big restructuring.
The boycott of "vested interests" could be fierce, he added.
Extraction from 15,000 sources and 1,800 potential sources-
Page report, Executive Summary details how the growing footprint and appetite of our species have compromised the natural renewal of the resources that sustain civilization, starting with fresh water, breathable and productive soil.
A report by the United Nations climate science team in October depicts the same terrible picture of global warming, and also emphasizes the need for social transformation on an unprecedented scale, to limit the temperature rise to 1. 5C (2. 7F).
The global thermometer has risen 1C, and by the end of this century, 3C will rise according to the current trend.
Climate change and the loss of biodiversity have proved to be mutually reinforcing in the vicious cycle.
Deforestation and industrial agriculture are the main drivers of the decline in species and ecosystems, but they also account for at least 25-
Greenhouse gas emissions.
Trees release planet
When carbon dioxide is reduced, warming, the destruction of tropical forests covering England's area every year will shrink the plant sponges that help absorb carbon dioxide.
In turn, global warming has driven thousands of animals and plants out of comfort zones, fuelling recent heat waves and droughts in Australia, Indonesia, Russia that have triggered unprecedented fires, Portugal, California and Greece.
The new report warns that the overlapping drivers of global warming and loss of biodiversity suggest a common solution, but it is also likely to trigger policy conflicts.
The green global economy's plan retains the key role of burning biofuels and locking in carbon dioxide releases, a technology known as BECCS.
But large areas of land are needed to grow energy crops of such scale --
About twice as much as India.
It will be in conflict with the expansion of protected areas and the efforts for afforestation, not to mention food production.
For the first time, UN agencies ranked the top five causes of species disappearance and natural degradation.
In the long run, the first two habitats are reduced or degraded, looking for food or trade --often illicit -in body parts.
For example, with the exception of 7%, all major marine fish stocks are being reduced or developed to the limits of sustainability, despite efforts by regional management organizations to sustainably capture.
Global warming ranks third on the list, but may rise.
"We can see that the signal of climate change is getting stronger and faster . "
Sandra Diaz, professor at the National University of Cordoba, Argentina, said.
The fourth and fifth are pollution.
Dumping 0. 4 billion tons of heavy metals, toxic sludge and other waste into the ocean and rivers every year
There are also alien species such as mice, mosquitoes, snakes, and plants that hang on ships or planes.
"There are also two indirect drivers of biodiversity loss and climate change ---
The world's population and consumption capacity are growing . "
The heavily negotiated text did not set a benchmark for progress or a "last chance" deadline for action, as did the 2018 climate report.
The panel was also not authorized to make clear policy proposals.
But it does point clearly to the actions that need to be taken: reducing meat consumption, stopping deforestation in tropical countries, stopping luxury consumption, cutting unfair subsidies and accepting the concept of low spendinggrowth economy.
The report will "serve as the basis for redefining our goals", ahead of a key meeting of the United Nations convention on biodiversity in China in October 2020, co-
