“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

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 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.”

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…”

WWF International’s Living Planet Report 2016 – a summary: “Global biodiversity is declining at an alarming rate, putting the survival of other species and our own future at risk. The latest edition of WWF’s Living Planet Report brings home the enormity of the situation – and how we can start to put it right. The Living Planet Index reveals that global populations of fish, birds, mammals, amphibians and reptiles declined by 58 per cent between 1970 and 2012.

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…”

A 2015 article in The Guardian (UK) newspaper titled “How humans are driving the sixth mass extinction.”
Excerpts: “The impacts of a still-avoidable sixth mass extinction would likely be so massive they’d be best described as science fiction. It would be catastrophic, widespread and, of course, irreversible. In the past, it has taken life ten to thirty million years to recover after such an extinction…
The team of geologists and biologists say that our current extinction crisis is unique in Earth’s history due to four characteristics…
The scientists agree that to avoid mass extinction – and tackle the current environmental crisis – is possible but will require large-scale changes not only in how society operates but how humans view their relation to the natural world…
Ellis agreed that humans must move on from the view that we are somehow separate from nature (or that nature somehow exists separate from us) and, instead, embrace our role as “permanent shapers and stewards of the biosphere and the species within it.”…”

Excerpts: ‘We ignore the decline of other species at our peril – for they are the barometer that reveals our impact on the world that sustains us’…
By 2020, the populations of mammals, birds, fish, reptiles and other vertebrate species are on course to have fallen by more than two-thirds over a period of just 50 years, the Living Planet report found.
The current rate of extinction is about 100 times faster than is considered normal – greater than during some of the previous five mass extinctions in the Earth’s history…
“Humanity’s misuse of natural resources is threatening habitats, pushing irreplaceable species to the brink and threatening the stability of our climate.”…

“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…
the overuse of resources would ultimately lead to conflicts…
Currently, the global population is cutting down trees faster than they regrow, catching fish faster than the oceans can restock, pumping water from rivers and aquifers faster than rainfall can replenish them and emitting more climate-warming carbon dioxide than oceans and forests can absorb…
The report concludes that today’s average global rate of consumption would need 1.5 planet Earths to sustain it. But four planets would be required to sustain US levels of consumption, or 2.5 Earths to match UK consumption levels…

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…”

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.

From a 2015 article titled “Meat-Eaters Are The Number One Cause Of Worldwide Species Extinction, New Study Warns” – some excerpts: “According to a recent study published in Science of the Total Environment by researchers at Florida International University in Miami, livestock production’s impact on land use is “likely the leading cause of modern species extinctions” — a problem the researchers think will only get worse as population growth increases the global demand for meat…
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.”…
The study says that in order to limit the worst biodiversity losses, the average diet should get no more than 10 percent of its calories from meat, and that pork, chicken, and fish are less resource-intensive options for meat eaters…”

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…”
