“The Holocene extinction, otherwise referred to as the sixth extinction or Anthropocene extinction, is the ongoing extinction event of species during the present Holocene epoch, mainly due to human activity. The large number of extinctions spans numerous families of plants and animals, including mammals, birds, amphibians, reptiles and arthropods. With widespread degradation of highly biodiverse habitats such as coral reefs and rainforest, as well as other areas, the vast majority of these extinctions is thought to be undocumented. The current rate of extinction of species is estimated at 100 to 1,000 times higher than natural background rates…” https://en.wikipedia.org/wiki/Holocene_extinction

2019 news report: “Loss of biodiversity is just as catastrophic as climate change. Nature is being eroded at rates unprecedented in human history but we still have time to stave off mass extinctions … We have all assumed that nature would always be here for us and our children. However, our boundless consumption, shortsighted reliance on fossil fuels and our unsustainable use of nature now seriously threaten our future …
We have entered an era of rapidly accelerating species extinction, and are facing the irreversible loss of plant and animal species, habitats and vital crops, while coming face to face with the horrific impacts of global climate change …
Despite the profound threat of biodiversity loss, it is climate change that has long been considered the most pressing environmental concern. That changed this week in Paris, when representatives from 130 nations approved the most comprehensive assessment of global biodiversity ever undertaken.
The report, spearheaded by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), found that nature is being eroded at rates unprecedented in human history.
One million species are currently threatened with extinction and we are undermining the entire natural infrastructure on which our modern world depends …”

Summary of the “Living Planet Report 2018” from WWF (World Wide Fund For Nature): “On average, we’ve seen an astonishing 60% decline in the size of populations of mammals, birds, fish, reptiles, and amphibians in just over 40 years, according to WWF’s Living Planet Report 2018 … We’re facing a rapidly closing window for action and the urgent need for everyone—everyone—to collectively rethink and redefine how we value, protect, and restore nature …”

2018 news report in The Guardian: “Humanity has wiped out 60% of mammals, birds, fish and reptiles since 1970, leading the world’s foremost experts to warn that the annihilation of wildlife is now an emergency that threatens civilisation.
The new estimate of the massacre of wildlife is made in a major report produced by WWF and involving 59 scientists from across the globe. It finds that the vast and growing consumption of food and resources by the global population is destroying the web of life, billions of years in the making, upon which human society ultimately depends for clean air, water and everything else … ”

2019 news report: “The Rapid Decline Of The Natural World Is A Crisis Even Bigger Than Climate Change.”
Excerpts: “The last year has seen a slew of brutal and terrifying warnings about the threat climate change poses to life. Far less talked about but just as dangerous, if not more so, is the rapid decline of the natural world. The felling of forests, the over-exploitation of seas and soils, and the pollution of air and water are together driving the living world to the brink, according to a huge three-year, U.N.-backed landmark study to be published in May …
nature’s ability to contribute food and fresh water to a growing human population is being compromised in every region on earth …
A February report from the U.N. warned that the loss of soil, plants, trees and pollinators such as birds, bats and bees undermines the world’s ability to produce food …
All of this comes at a huge cost and has implications for the systems that prop up life on this planet, throwing into doubt the ability of humans to survive …
Animal populations have declined by 60 percent since 1970, driven by human actions …
insects, vital to the diets of other animals, as well as the pollinators of our food, are facing a bleak future as populations appear to be collapsing …
saving nature will require a major rethink of how we live and how we think about nature, but that it is possible to turn this dire situation around if governments want it to happen.”

The Guardian news UK, May 2018: “Human race just 0.01% of all life but has eradicated most other living things… Our dietary choices have a vast effect on the habitats of animals, plants and other organisms… The destruction of wild habitat for farming, logging and development has resulted in the start of what many scientists consider the sixth mass extinction of life to occur in the Earth’s four billion year history. About half the Earth’s animals are thought to have been lost in the last 50 years…
The new work** reveals that farmed poultry today makes up 70% of all birds on the planet, with just 30% being wild. The picture is even more stark for mammals – 60% of all mammals on Earth are livestock, mostly cattle and pigs, 36% are human and just 4% are wild animals…”
** The 2018 report titled “The Biomass Distribution on Earth” was published in the Proceedings of the National Academy of Sciences of the United States of America (PNAS) at https://www.pnas.org/content/115/25/6506

This is also true for wild and domesticated birds, for which the biomass of domesticated poultry (≈0.005 Gt C, dominated by chickens) is about threefold higher than that of wild birds (≈0.002 Gt C; SI Appendix, Table S12). In fact, humans and livestock outweigh all vertebrates combined, with the exception of fish …”

2018 news report: “What is Biodiversity and Why Does It Matter To Us?”
Excerpts: “The air you breathe, the water you drink and the food you eat all rely on biodiversity, but right now it is in crisis – because of us…
A more philosophical way of viewing biodiversity is this: it represents the knowledge learned by evolving species over millions of years about how to survive through the vastly varying environmental conditions Earth has experienced. Seen like that, experts warn, humanity is currently “burning the library of life”…
Some examples are obvious: without plants there would be no oxygen and without bees to pollinate there would be no fruit or nuts.
Others are less obvious – coral reefs and mangrove swamps provide invaluable protection from cyclones and tsunamis for those living on coasts, while trees can absorb air pollution in urban areas…
The extinction rate of species is now thought to be about 1,000 times higher than before humans dominated the planet, which may be even faster than the losses after a giant meteorite wiped out the dinosaurs 65m years ago. The sixth mass extinction in geological history has already begun, according to some scientists…
Billions of individual populations have been lost all over the planet, with the number of animals living on Earth having plunged by half since 1970. Abandoning the normally sober tone of scientific papers, researchers call the massive loss of wildlife a “biological annihilation” representing a “frightening assault on the foundations of human civilisation”…
What’s destroying biodiversity?
We are, particularly as the human population rises and wild areas are razed to create farmland, housing and industrial sites. The felling of forests is often the first step…
Poaching and unsustainable hunting for food is another major factor…
Pollution is a killer too…
The hardest hit of all habitats may be rivers and lakes, with freshwater animal populations in these collapsing by 81% since 1970, following huge water extraction for farms and people, plus pollution and dams…
Could the loss of biodiversity be a greater threat to humanity than climate change?
Yes – nothing on Earth is experiencing more dramatic change at the hands of human activity. Changes to the climate are reversible, even if that takes centuries or millennia. But once species become extinct, particularly those unknown to science, there’s no going back…
What can be done?
Giving nature the space and protection it needs is the only answer. Wildlife reserves are the obvious solution, and the world currently protects 15% of land and 7% of the oceans. But some argue that half the land surface must be set aside for nature…
We can all help. Most wildlife is destroyed by land being cleared for cattle, soy, palm oil, timber and leather. Most of us consume these products every day… Choosing only sustainable options helps, as does eating less meat, particularly beef, which has an outsized environmental hoofprint…”

A 2015 science journal report titled “BIODIVERSITY CONSERVATION: THE KEY IS REDUCING MEAT CONSUMPTION” some excerpts:
“The consumption of animal-sourced food products by humans is one of the most powerful negative forces affecting the conservation of terrestrial ecosystems and biological diversity. Livestock production is the single largest driver of habitat loss, and both livestock and feedstock production are increasing in developing tropical countries where the majority of biological diversity resides…
Livestock production is also a leading cause of climate change, soil loss, water and nutrient pollution, and decreases of apex predators and wild herbivores, compounding pressures on ecosystems and biodiversity. It is possible to greatly reduce the impacts of animal product consumption by humans on natural ecosystems and biodiversity while meeting nutritional needs of people, including the projected 2–3 billion people to be added to human population…
We suggest that impacts can be remediated through several solutions: (1) reducing demand for animal-based food products and increasing proportions of plant-based foods in diets, the latter ideally to a global average of 90% of food consumed; …
Such efforts would also impart positive impacts on human health through reduction of diseases of nutritional extravagance…”

From a 2017 BBC article titled “How Western Civilisation Could Collapse” some excerpts: “It should come as no surprise that humanity is currently on an unsustainable and uncertain path – but just how close are we to reaching the point of no return?…
there are two factors that matter: ecological strain and economic stratification. The ecological category is the more widely understood and recognised path to potential doom, especially in terms of depletion of natural resources such as groundwater, soil, fisheries and forests – all of which could be worsened by climate change…
While we are all in this together, the world’s poorest will feel the effects of collapse first. Indeed, some nations are already serving as canaries in the coal mine for the issues that may eventually pull apart more affluent ones. Syria, for example…
Our world would become an increasingly ugly place, one defined by a scramble over limited resources and a rejection of anyone outside of our immediate group. Should we find no way to get the wheels back in motion, we’d eventually face total societal collapse…”

From a 2019 report: “alarm over ‘massive extinction’ of insects … with disastrous impacts on food chains and habitats, researchers say ... the first synthesis of 73 studies on entomological fauna around the world over the past 40 years … They calculated that over 40 percent of insect species are threatened with extinction, and each year about 1 percentage point is added to the list. This is equivalent, they noted, to “the most massive extinction episode” since the dinosaurs disappeared.
The main drivers appeared to be habitat loss and land conversion to intensive agriculture and urbanization, followed by pollution, mainly from pesticides and fertilizers, invasive species and climate change.
“The conclusion is clear,” they wrote. “Unless we change our ways of producing food, insects as a whole will go down the path of extinction in a few decades.”

From a 2017 news report in The Guardian (UK) titled “INSECTAGEDDON: FARMING IS MORE CATASTROPHIC THAN CLIMATE BREAKDOWN” – Excerpts: “The shocking collapse of insect populations hints at a global ecological meltdown.
Which of these would you name as the world’s most pressing environmental issue?… One is industrial fishing, which, all over the blue planet, is now causing systemic ecological collapse. The other is the erasure of non-human life from the land by farming…
According to the UN Food and Agriculture Organisation, at current rates of soil loss, driven largely by poor farming practice, we have just 60 years of harvests left… productivity is already declining on 20% of the world’s cropland…
A study published this week in the journal Plos One reveals that flying insects surveyed on nature reserves in Germany have declined by 76% in 27 years. The most likely cause of this Insectageddon is that the land surrounding those reserves has become hostile to them: the volume of pesticides and the destruction of habitat have turned farmland into a wildlife desert…
Insects, of course, are critical to the survival of the rest of the living world. Knowing what we now know, there is nothing surprising about the calamitous decline of insect-eating birds. Those flying insects – not just bees and hoverflies but species of many different families – are the pollinators without which a vast tract of the plant kingdom, both wild and cultivated, cannot survive. The wonders of the living planet are vanishing before our eyes.
As a UN report published in March explained, the notion that pesticide use is essential for feeding a growing population is a myth. A recent study in Nature Plants reveals that most farms would increase production if they cut their use of pesticides. A study in the journal Arthropod-Plant Interactions shows that the more neonicotinoid pesticides were used to treat rapeseed crops, the more their yield declines. Why? Because the pesticides harm or kill the pollinators on which the crop depends.
Farmers and governments have been comprehensively conned by the global pesticide industry…
To save ourselves and the rest of the living world, here’s what we need to do:
1. We need a global treaty to regulate pesticides…
2. We need environmental impact assessments for the farming and fishing industries…
3. We need firm rules based on the outcomes of these assessments, obliging those who use the land to protect and restore the ecosystems on which we all depend.
4. We need to reduce the amount of land used by farming, while sustaining the production of food. The most obvious way is greatly to reduce our use of livestock: many of the crops we grow and all of the grazing land we use are deployed to feed them. One study in Britain suggests that, if we stopped using animal products, everyone in Britain could be fed on just 3m of our 18.5m hectares of current farmland (or on 7m hectares if all our farming were organic). This would allow us to create huge wildlife and soil refuges: an investment against a terrifying future…”

From a 2016 article in ABC News (Australia) titled “Radical overhaul needed to halt Earth’s sixth great extinction event.”
Excerpts: “human civilisation relies on biodiversity for its very existence. The plants, animals and microorganisms with which we share the Earth supply us with vital ecosystem services.
These include regulating the climate, supplying clean water, limiting floods, running nutrient cycles essential to agriculture and forestry, controlling serious crop pests and carriers of diseases, and providing beauty, spiritual and recreational benefits…
species have been disappearing far faster than before. Since 1900, reptiles are vanishing 24 times faster, birds 34 times faster, mammals and fishes about 55 times faster, and amphibians 100 times faster than they have in the past.
For all vertebrate groups together, the average rate of species loss is 53 times higher than the background rate…
Humans cannot keep growing in numbers and consuming ever more land, water and natural resources and expect all to be well...
We also have to move urgently to slow human population growth, reduce over-consumption and over-hunting, save remaining wilderness areas, expand and better protect our nature reserves, invest in conserving critically endangered species, and vote for leaders who make these issues a priority.
Without decisive action, we are likely to hack off vital limbs of the tree of life that could take millions of years to recover.”

“Animal Extinction Hidden in Plain Sight – A new study suggests that the overrepresentation of wild animals—lions, tigers, giraffes, etc.—in our everyday lives (toys, films, ads) makes us forget that they are on the verge of extinction. Researchers believe companies should pay ‘image rights’ when using such animals to help conservation efforts. The study’s principal author ecologist Franck Courchamp explains…”
From the study report: “we identify the 10 most charismatic animals and show that they are at high risk of imminent extinction in the wild. We also find that the public ignores these animals’ predicament and we suggest it could be due to the observed biased perception of their abundance, based more on their profusion in our culture than on their natural populations…
According to our hypothesis, this biased perception would be likely to last as long as the massive cultural and commercial presence of charismatic species is not accompanied by adequate information campaigns about the imminent threats they face.”

The Guardian, UK newspaper, 2017: “Why factory farming is not just cruel – but also a threat to all life on the planet.”
Excerpts: “It’s time the world woke up to the real impact of modern, industrial farming, says Philip Lymbery, author of Farmageddon and the Deadzone…
In the US in August, meanwhile, campaigners identified the world’s largest ever “deadzone” – an area in the sea where pollutants from farms create algal blooms that kill off or disperse marine life – and singled out the US’s heavily industrialised factory farm system as a major cause…
“The crops fed to industrially reared animals worldwide could feed an extra four billion [people] on the planet.”
As the global demand for cheap meat grows, the expansion of agricultural land is putting more and pressure on our forests, rivers and oceans, contributing to deforestation, soil erosion, marine pollution zones and the global biodiversity crisis, he said.
“The UN has warned that if we continue as we are, the world’s soils will have effectively gone within 60 years. And then what? We shouldn’t look to the sea to bail us out because commercial fisheries are expected to be finished by 2048…
“The rainforest homes of the likes of jaguars and the critically endangered sumatran elephants are being razed to make way for intensive crop production and plantations that are feeding factory farm animals … the mixed farm habitats of once common farmland birds such as barn owls, turtle doves and skylarks are being stripped away, and … vast quantities of wild fish are being scooped up to feed industrially reared farmed fish and chickens and pigs, leaving the likes of penguins, puffins and other species starving.”…
Antibiotic use is another red flag area. “There is now overwhelming evidence that the routine prophylactic use of antibiotics is leading to the rise of antibiotic resistant superbugs, and the World Health Organisation has issued warnings that if we don’t do something to curb antibiotic use in both human and animal medicine we will face a post-antibiotic era where currently treatable diseases will once again kill.”…”

From a 2017 article in The Conversation – “How changing your diet could save animals from extinction” – some excerpts: “Transforming large swaths of the tropics into farmland could render almost one-third of wildlife there extinct, new research suggests…
Aside from protecting land, food can be grown at little to no cost to biodiversity. For example, small-holder agro-ecological farming, which uses diverse cropping techniques along with fewer chemical fertilizers and pesticides, can produce large quantities of nutritious food at little to no cost to wildlife…
All of this raises the question: How can we eat well without harming wildlife? One simple step we can all take right now that would have a far greater impact than any other (aside from having fewer children): Cut out the grain-fed beef.
The inefficiency of feeding livestock grain to turn them into meals for humans makes a diet heavy in animals particularly harsh on the Earth’s resources. For example, in the United States, it takes 25 kilograms of grain to produce one kilogram of beef…
To make matters worse, the grain we feed animals is the leading driver of deforestation in the tropics. And it’s a hungry beast: our cows, pigs, and poultry devour over one-third of all crops we grow. Indeed, the grain we feed to animals in the U.S. alone could feed an additional 800 million people if it were eaten by us directly — more than the number of people currently living in hunger [globally].
Livestock quietly causes 10 times more deforestation than the palm oil industry but seems to get about 10 times less media attention. While it’s certainly true that avoiding unsustainable palm oil is a good idea, avoiding eating animals that were raised on grain is an even more effective conservation tactic…
Nearly one-third of tropical animal species face extinction if humans do not curb our growing appetites for beef, pork and other land-intensive meats…”

“Earth has lost half of its wildlife in the past 40 years, says WWF” is the title of a 2014 article in The Guardian (UK). Excerpts: “Species across land, rivers and seas decimated as humans kill for food in unsustainable numbers and destroy habitats...
“We have lost one half of the animal population and knowing this is driven by human consumption, this is clearly a call to arms and we must act now,” said Mike Barratt, director of science and policy at WWF. He said more of the Earth must be protected from development and deforestation, while food and energy had to be produced sustainably…

A 2017 study titled “More than 75 percent decline over 27 years in total flying insect biomass in protected areas.” Excerpts: “Loss of insect diversity and abundance is expected to provoke cascading effects on food webs and to jeopardize ecosystem services... we used a standardized protocol to measure total insect biomass… over 27 years in 63 nature protection areas in Germany (96 unique location-year combinations)… Our analysis estimates a seasonal decline of 76%, and mid-summer decline of 82% in flying insect biomass over the 27 years of study.
We show that this decline is apparent regardless of habitat type, while changes in weather, land use, and habitat characteristics cannot explain this overall decline. This yet unrecognized loss of insect biomass must be taken into account in evaluating declines in abundance of species depending on insects as a food source, and ecosystem functioning in the European landscape…”

Dozens of species lost more than 50 per cent of their populations between 1970 and 2014… Even relatively abundant birds are dwindling in number, the report says…
Two groups of birds have been especially affected: grasslands species, which have been hurt by the conversion of their habitat into farmland, and insect eaters such as swallows and flycatchers, whose decline is less obvious but may be a result of falling insect populations related to pesticide use.

A 2010 report by Avian Conservation and Ecology states: “North American birds that feed on aerial insects are experiencing widespread population declines… The pattern of decline also shows a striking geographical gradient, with aerial insectivore declines becoming more prevalent towards the northeast of North America. Declines are also more acute in species that migrate long distances compared to those that migrate short distances… The taxonomic breadth of these downward trends suggests that declines in aerial insectivore populations are linked to changes in populations of flying insects, and these changes might be indicative of underlying ecosystem changes.”

Regards the loss of native animals in Australia the below notes are from a 2015 report about how livestock farming (pastoralism) increases the threats posed by introduced carnivores and herbivores:
“The highly distinctive and mostly endemic Australian land mammal fauna has suffered an extraordinary rate of extinction (>10% of the 273 endemic terrestrial species) over the last ∼200 y: in comparison, only one native land mammal from continental North America became extinct since European settlement. A further 21% of Australian endemic land mammal species are now assessed to be threatened…
Pastoralism based on introduced sheep and cattle is now the dominant land use across much of Australia, and many other introduced herbivores (notably including the rabbit, goat, donkey, camel, horse, and buffalo) collectively occur abundantly beyond the pastoral estate across the entire Australian land mass, including in many conservation reserves.
Competition with, and habitat degradation caused by, introduced herbivores has also been detrimental to many Australian mammals, as demonstrated by livestock removal experiments and correlative studies that compare mammal assemblages in comparable areas with and without introduced herbivores…
Many of these diverse threatening factors directly or indirectly increase the intensity and impact of predation by feral cats and foxes.
In many areas, shelter sites for native mammals (including hollow logs and dense ground vegetation) are reduced by the current fire regime and/or by grazing pressure of livestock and feral herbivores, allowing more effective hunting by feral predators.
Across extensive areas of mainland Australia, dingo Canis lupus dingo populations have been reduced substantially by the pastoral industry, using exclosure fencing, concerted trapping, and poison-baiting programs, and such reduction in a top-order predator typically results in increases in the abundance of foxes and feral cats with consequently greater predation pressure on native mammals…
Some other instances of recovery of Australian threatened mammals have involved the broadscale removal of livestock and feral herbivores…”

Several studies have suggested that the Earth is currently in the midst of the sixth mass extinction, caused largely by human activities. Animals are hunted and sold for trade, climate change is disrupting migration and mating patterns, extreme weather is threatening animal populations, and deforestation is fragmenting crucial habitat. But all of those causes… pale in comparison to the threat of habitat loss driven by demand for meat, which the study claims “will cause more extinctions than any other factor.”…

From a 2013 article on The Conversation website: “Mass extinctions due to rapidly escalating levels of CO2 are recorded since as long as 580 million years ago. As our anthropogenic global emissions of CO2 are rising, at a rate for which no precedence is known from the geological record with the exception of asteroid impacts, another wave of extinctions is unfolding…
In February 2013, CO2 levels had risen to near 396.80ppm at Mauna Loa Atmospheric Observatory, compared to 393.54ppm in February 2012. This rise – 3.26ppm per year – is at the highest rate yet recorded. Further measurements show CO2 is at near 400ppm of the atmosphere over the Arctic. At this rate the upper stability threshold of the Antarctic ice sheet, defined at about 500–600ppm CO2 would be reached later this century…
Our global carbon reserves – including coal, oil, oil shale, tar sands, gas and coal-seam gas – contain considerably more than 10,000 billion tonnes of carbon… This amount of carbon, if released into the atmosphere, is capable of raising atmospheric CO2 levels to higher than 1000ppm. Such a rise in atmospheric radiative forcing will be similar to that of the Paleocene-Eocene boundary thermal maximum (PETM), which happened about 55 million years-ago… But the rate of rise surpasses those of this thermal maximum by about ten times.
The rapid opening of the Arctic Sea ice, melting of Greenland and west Antarctic ice sheets, and rising spate of floods, heat waves, fires and other extreme weather events may signify a shift in state of the climate, crossing tipping points…
Continuing emissions contravene international laws regarding crimes against humanity and related International and Australian covenants. In the absence of an effective global mitigation effort, governments world-wide are now presiding over the demise of future generations and of nature, tracking toward one of the greatest mass extinction events nature has seen. It is time we learned from the history of planet Earth.”
From a 2013 article titled “Another link between CO2 and mass extinctions of species” by Andrew Glikson, Earth and paleo-climate scientist, Australian National University; article at https://theconversation.com/another-link-between-co2-and-mass-extinctions-of-species-12906
“Trends in Atmospheric Carbon Dioxide” are listed on a web-page of the U.S. Government’s National Oceanic & Atmospheric Administration at https://www.esrl.noaa.gov/gmd/ccgg/trends/global.html As of May 2017 the level is listed as being 406.36ppm (parts per million) for “mean carbon dioxide globally averaged over marine surface sites…”
From a 2000 page on the site of the United Nations Framework Convention on Climate Change (UNFCCC) is titled “How human activities produce greenhouse gases.”
Some excerpts: “Carbon dioxide from the burning of fossil fuels is the largest single source of greenhouse gas emissions from human activities. The supply and use of fossil fuels accounts for about three quarters of mankind’s carbon dioxide (CO2) emissions… Deforestation is the second largest source of carbon dioxide… The second-most important greenhouse gas after carbon dioxide, methane is produced by cattle, dairy cows, buffalo, goats, sheep, camels, pigs, and horses. Most livestock-related methane emissions are produced by “enteric fermentation” of food by bacteria and other microbes in the animals’ digestive tracts; another source is the decomposition of animal manure. Livestock account for about one-quarter of the methane emissions from human activities, totalling some 100 million tonnes a year…”

March 2018 article: “The destruction of biodiversity is an equally or perhaps even more pressing crisis than climate change, which has fuelled the decline. The problem is not only the extinction of species, but the slashing of populations. The number of land animals worldwide has fallen by as much as half since 1970…
As experts point out, the threat to other species is a threat to our own survival. Self-preservation demands the preservation of flora and other fauna, whose interconnection we cannot hope to understand. We are recklessly destroying the species that make oxygen and protect us from extreme weather; the food chains on which we depend; the sources of medicines we may need…
We do not have to consume so much, burn such vast quantities of coal, raze all our forests and fill our oceans with plastic. Changing the way we live will not be easy. But it is necessary for our own sake too…”
