There is No Future Unless We Stop Destroying the Natural World.

Reverse nature's decline or there is no future - UN

The United Nations' biodiversity chief says global talks under way in Montreal are the "last chance" to reverse the destruction of the natural world.

"Biodiversity is the foundation of life. Without it, there is no life," Elizabeth Maruma Mrema stated.

But she is worried about the amount of work still needed for the 196 countries to reach an agreement.

Climate change 2022: More studies needed on possibility of human extinction

heat

Catastrophic climate change outcomes, including human extinction, are not being taken seriously enough by scientists, a new study says.

The authors say that the consequences of more extreme warming - still on the cards if no action is taken - are "dangerously underexplored".

They argue that the world needs to start preparing for the possibility of what they term the "climate endgame".

They want UN scientists to investigate the risk of catastrophic change. According to this new analysis, the closest attempts to directly understand or address how climate change could lead to global catastrophe have come from popular science books such as The Uninhabitable Earth and not from mainstream science research.

Human Dependency on Nature

Humanity depends on Nature - on habitat for food availablity, pollution control, water purification, and agriculture; on other species for food availability, pollution control and pollination; on the atmospheric and oceanic currents for temperature control and freshwater generation and distribution; on atmosphic layers to protect us from cosmic radiation; and much, much more.

We could never afford to do what Nature does for us - we don't have the capacity or ability, and it would cost us thousands or millions times more than the total wealth of the planet - if we could.

Furthermore, human engineering, rather than replacing Nature, only causes more pollution, which makes the situation worse.

Neither can we find another planet in Space to go live on. We do not know of any other habitable planets, and we do not have the technology to get us there, when we do. Furthermore, this "option" will only be available for a very select few and will be horribly expensive, and won't come before the 22nd century, most likely. Planet Earth and our Human civilization won't survive that long unless we change the way we live dramatically.

The only answer for our Human survival is to reduce and limit our numbers, reduce and limit our development and destruction of the natural world, and reduce and limit our types and amounts of pollution. That is the only way we can save Nature, which we are part of, and upon which we depend absolutely.

Unsustainable logging, fishing and hunting 'driving extinction' - 2022

One in five people around the world rely on wild animals, plants and fungi for food and livelihoods, according to a landmark assessment.

But many wild species are not being harvested sustainably, putting food security at risk, the report found.

In 2019, experts estimated that one million plants and animals could go extinct in coming decades.

And much of this is being driven by unsustainable fishing, hunting and logging.

Now a new report by the same influential body concludes that the sustainable use of wild species is critical for people and nature.

And climate change and increased demand is likely to push more species to the brink, putting food security at risk.

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) is conservation scientists' equivalent of the IPCC group of climate scientists.

Their most recent assessment, approved by 139 countries in Bonn, Germany, focuses on how fishing, hunting and logging can be carried out more sustainably without damaging biodiversity and food security.

It found that billions of people across the world rely on 50,000 species of wild animals, plants and fungi for food, medicine, fuel, income and other purposes.

The assessment paints a picture of widespread exploitation of nature, with about a third of wild fish in the ocean overfished, more than 10% of wild trees threatened by unsustainable logging, and more than 1,300 mammals pushed to extinction by unsustainable hunting.

World's wilderness reduced by a tenth since 1990s - 2015

A tenth of the world's wilderness has vanished in the past two decades, research shows. New maps show "alarming losses" of pristine landscapes, particularly in South America and Africa, according to World Conservation Society scientists. They argue in Current Biology that wild areas are ignored in international conservation agreements, despite their ecological and cultural value.

About 20% of the world's land area is classed as wilderness. By this, scientists mean landscapes free of large-scale human disturbances such as housing, development and industry. The majority of these untouched spaces are found in North America, north Asia, north Africa and Australia. They are often home to indigenous peoples as well as endangered plants and animals.

James Watson of the University of Queensland, Australia, and the US Wildlife Conservation Society in New York said wilderness areas "are completely ignored in environmental policy". "International policy mechanisms must recognise the actions needed to maintain wilderness areas before it is too late," said Prof Watson. "We probably have one to two decades to turn this around."

Brazil drought - deforestation and slash and burn land clearing causing drought in Sao Paulo, Brazil

Mud in reservoir: Levels in the Cantareira reservoir system remain dangerously low. Fires to clear land for agriculture in Sao Felix Do Xingu municipality, Para, Brazil - June 20, 2009. In Brazil's biggest city, a record dry season and ever-increasing demand for water has led to a punishing drought. It has actually been raining quite heavily over the last few days in and around Sao Paulo but it has barely made a drop of difference. The main reservoir system that feeds this immense city is still dangerously low, and it would take months of intense, heavy rainfall for water levels to return to anything like normal. So how does a country that produces an estimated 12% of the world's fresh water end up with a chronic shortage of this most essential resource - in its biggest and most economically important city? It's interesting to note that both the local state government and the federal government have been slow to acknowledge there is a crisis, despite overwhelming evidence to the contrary. That might have been a politically expedient position to take during the recent election campaign, when the shortage of water in Sao Paulo was a thorny political issue, but the apparent lack of urgency in the city and wider state now is worrying many. At the main Cantareira reservoir system, which feeds much of this city's insatiable demand for water, things have almost reached rock bottom. Huge pipes suck out what water remains as the reservoir dips below 10% of its usual capacity.

Earth: Will the age of man be written in stone?

There have been a few times in the history of mankind when we nearly died out as a species. Anthropologists call these events “bottlenecks”, times when the population of humans shrank – perhaps to as few as 2,000 people over 50,000 years ago. At those levels, we would be categorised as an endangered species on the IUCN Red List, existing in even fewer numbers than wild tigers do today. We survived, and in fact we’ve thrived, mainly because we adapted our environment to suit our needs. But to what degree has the survival and triumph of our species changed our planet? The best people to answer this could well be those who have the grandest perspective. Geologists can take a 4.5-billion-year step back and look at the human impact on our planet in the context of its long history – they can identify changes in the rock record within layers of deposited sediments that build up and are compressed over time.

Conservation targets need billions in funding

Scientists say billions required to meet conservation targets

The most threatened species tend to be relatively cheap to save because of small range sizes.

 

Reducing the risk of extinction for threatened species and establishing protected areas for nature will cost the world over $76bn dollars annually. Researchers say it is needed to meet globally agreed conservation targets by 2020. The scientists say the daunting number is just a fifth of what the world spends on soft drinks annually. And it amounts to just 1% of the value of ecosystems being lost every year, they report in the journal Science.
