In North America, the report said five bumblebee species have undergone massive declines in range and abundance in the last 25 years, with one, Franklin's bumblebee, going extinct.

Birds, which often depend on insects as food and are better studied, also are in decline in many places, Goulson noted.

Mow your lawn less frequently and allow part of it to flower. View weeds such as dandelions -- which are great for bees -- as wildflowers and let them grow.

But gene drive technology is so powerful that leading researchers have urged scientists in the field to be cautious. A warning published in August in the prestigious journal Science, by teams in the UK, US, Australia and Japan, said that while gene drives have the potential to save lives and bring other benefits, the accidental release of modified organisms “could have unpredictable ecological consequences.”

They call on scientists to ensure that experimental organisms cannot escape from their labs, be released on purpose, or even find their way out accidentally in the event of a natural disaster. Researchers should also be open about the precautions they take to prevent an unintended release, they said.

In the latest study, mosquitoes were engineered to carry genes for antibodies that target the human malaria parasite, Plasmodium falciparum. When released into the wild, researchers believe the modified insects will breed with normal mosquitoes and pass the anti-malarial genes on to their young, making an ever-increasing proportion of future generations resistant to the malaria parasite.

In lab tests, the modified mosquitoes passed on their anti-malarial genes to 99.5% of their offspring, suggesting that the procedure was incredibly effective and efficient. To track which insects inherited the antibody genes, the scientists added a tracer gene that gave carriers red fluorescent eyes.

It’s worth noting that the original version of the Green New Deal was devised by the left-leaning British National Economic Foundation, as a means for recovery after the 2008 economic collapse

Once Labour’s full, staggeringly bold proposals were unveiled, support for the party soared

Labour climbed a full 20 points in the six weeks of the 2017 campaign, robbing the Tories of a majority in the Parliament

So it seems to me there is a massive opportunity for the left now across the Western world. Look at how popular a 70 percent top rate is … in America! The left is correct to sense a huge opportunity and they are right, I think, to be bold.

I wrote about Jeremy Corbyn’s Labour last year in these pages, and that, under his leadership, “it turned out to be difficult to propel a new movement of left radicalism without simultaneously tapping into a vein of left extremism,” and that seems to me to be precisely the challenge in the U.S. as well

the full package from the contemporary radicalized left in both the U.K. and U.S. brings with it far more troubling ideas

If they insist on calling our multicultural and multiracial democracy a manifestation of “white supremacy,” they will empower real white supremacists.

A passion for social justice curdles into attacks on free speech

Postmodern critical gender theory denies any meaningful natural differences between men and women, and casts an entire sex as inherently problematic

Concern about mass immigration is dismissed as nothing but racism and xenophobia.

so Labour, after so much promise and success, has not been able to get any sustainable polling lead over the most shambolic Tory government in memory.

If the Democrats want to fight the next election on the need for a radical rebalancing of the economy in favor of the middle and working class, for massive investment in new green technology, for higher taxes on the superrich, and for health-care security for all Americans, they can win

If they conflate those goals with extremist rhetoric about abolishing everyone’s current health insurance, and starting from scratch, as the Green New Deal advises, not so much

If they insist that men and women are indistinguishable, that girls can have penises and boys can have periods, as transgender ideology now demands, they’ll seem nuts to most fair-minded people.

Hostility to the policies of the state of Israel — a perfectly legitimate position — morphs swiftly into ugly anti-Semitic tropes

It’s not easy to find any heroes in Washington these days, so allow me to eulogize one. Walter Jones was a longtime Republican congressman from North Carolina, who died earlier this wee

Are they really capable of fucking this up once again? The answer that is emerging in the first months of the new Democratic House is: of course they can.

we may be underestimating what the constant drumbeat of news about the accelerating sixth great extinction has been doing to us psychologically.

I’m haunted all the time by the knowledge of what my lifetime will have witnessed. Humans are committing countless species to death; we are destroying the life of our oceans and skies; we are changing the planet’s ecosystem more quickly than at any time since the asteroids wiped out the dinosaurs. From the perspective of life itself, we are conducting a holocaust of the natural world. How is the knowledge of this not traumatizing?

A new report from the Institute for Public Policy Research notes, according to the BBC, that “since 1950, the number of floods across the world has increased by 15 times, extreme temperature events by 20 times, and wildfires seven-fold.”

Last week, research emerged showing that the insect biomass is declining by 2.5 percent a year, which means that we may wipe out the entire insect population within a century — and lose a quarter of it in the next ten years.

This amounts to what Jill Kieldash describes as the “actual structural and functional collapse of the natural systems which have supported life on Earth for the last 400 million years.”

I don’t know how this paradigm affects you every day, but it is for me the gutting context for everything, a growing nausea laced with guilt and shame.

In a century, we will have destroyed this Earth as we have known it — in absolutely full awareness of what we are doing. It’s the greatest crime humanity has ever committed

One answer could be that they are behaving in a classic way when a catastrophe strikes: They’re traumatized by this knowledge, and they cope with this trauma by a classic form of disassociation. In fact, we are all living through this collective trauma

Once we become aware of its true scope, depth, and accelerating pace, we then begin to view everything else through the traumatic lens of the climate crisis

How could anyone with a reasonably realistic, educated worldview not be haunted by the perpetual specter of Climate Trauma when considering fundamental life and identity choices?

I am not surprised by declining birth rates in the West. Having a child in today’s era means initiating another human being into the end of the world as we have known it

I find my own witnessing of the collapse of liberal democratic values in the West inseparable from the mass extinction of life on Earth our civilization has wrought — and the double depression this creates makes me want to escape

this collective trauma is never-ending. It’s a 9/11 all the time. Woodbury notes the similarity between our knowledge of future planetary collapse and a diagnosis of a terminal disease: “You may put it out of your mind for spells, but the grief associated with prospective loss comes at you in waves.

The challenge is to resist disassociation — which is “the human capacity to mentally escape an insufferable reality.

We are disassociating from America in our current dystopian politics. But we are also, more profoundly, disassociating ourselves from our deepest ecological reality: that we are killing what created us. And we cannot seem to stop.

If they call a border wall an “immorality” and refuse to fund a way to detain and humanely house the huge surge of migrant families and children now overwhelming the southern border (up 290 percent over the same period in 2018, with a record 1,800 apprehensions on Monday of this week alone!), they will rightly be called in favor of open borders

when it became clear that the Iraq War had been based on phony intelligence, he actually changed his mind. More than that: He took moral responsibility for his vote for the war, and rethought a great deal of his previous views. Ashamed of what he had done — and the lives lost because of the war — he went on to write 12,000 letters to family members of service members killed

he tirelessly fought to bring back war-making powers to the Senate, where they belong. He took on his own party leadership in demanding votes before military adventures

He was that very rare creature: a true Republican fiscal conservative

Of course a man of this character was a dogged defender of his own constituents, especially those in the military subjected to unfairness or injustice of any kin

This didn’t make him a liberal. It made him a conservative. And he proved that to be a conservative these days — a humane, decent, honest, principled conservative — you really have no place in the Republican Party

until now, the planet’s natural defense systems were better at fighting them off.

Today, climate warming is demolishing those defense systems, driving a catastrophic loss in biodiversity that, when coupled with reckless deforestation and aggressive conversion of wildland for economic development, pushes farms and people closer to the wild and opens the gates for the spread of disease.

ignoring how climate and rapid land development were putting disease-carrying animals in a squeeze was akin to playing Russian roulette.

the virus is believed to have originated with the horseshoe bat, part of a genus that’s been roaming the forests of the planet for 40 million years and thrives in the remote jungles of south China, even that remains uncertain.

China for years and warning that swift climate and environmental change there — in both loss of biodiversity and encroachment by civilization — was going to help new viruses jump to people.

. Roughly 60% of new pathogens come from animals — including those pressured by diversity loss — and roughly one-third of those can be directly attributed to changes in human land use, meaning deforestation, the introduction of farming, development or resource extraction in otherwise natural settings

Vector-borne diseases — those carried by insects like mosquitoes and ticks and transferred in the blood of infected people — are also on the rise as warming weather and erratic precipitation vastly expand the geographic regions vulnerable to contagion.

Climate is even bringing old viruses back from the dead, thawing zombie contagions like the anthrax released from a frozen reindeer in 2016, which can come down from the arctic and haunt us from the past.

It is demonstrating in real time the enormous and undeniable power that nature has over civilization and even over its politics.

it also makes clear that climate policy today is indivisible from efforts to prevent new infectious outbreaks, or, as Bernstein put it, the notion that climate and health and environmental policy might not be related is “a ​dangerous delusion.”

The warming of the climate is one of the principal drivers of the greatest — and fastest — loss of species diversity in the history of the planet, as shifting climate patterns force species to change habitats, push them into new regions or threaten their food and water supplies

What’s known as biodiversity is critical because the natural variety of plants and animals lends each species greater resiliency against threat and together offers a delicately balanced safety net for natural systems

As diversity wanes, the balance is upset, and remaining species are both more vulnerable to human influences and, according to a landmark 2010 study in the journal Nature, more likely to pass along powerful pathogens.

even incremental and seemingly manageable injuries to local environments — say, the construction of a livestock farm adjacent to stressed natural forest — can add up to outsized consequences.

Coronaviruses like COVID-19 aren’t likely to be carried by insects — they don’t leave enough infected virus cells in the blood. But one in five other viruses transmitted from animals to people are vector-borne

the number of species on the planet has already dropped by 20% and that more than a million animal and plant species now face extinction.

Americans have been experiencing this phenomenon directly in recent years as migratory birds have become less diverse and the threat posed by West Nile encephalitis has spread. It turns out that the birds that host the disease happen to also be the tough ones that prevail amid a thinned population

as larger mammals suffer declines at the hands of hunters or loggers or shifting climate patterns, smaller species, including bats, rats and other rodents, are thriving, either because they are more resilient to the degraded environment or they are able to live better among people.

It is these small animals, the ones that manage to find food in garbage cans or build nests in the eaves of buildings, that are proving most adaptable to human interference and also happen to spread disease.

Warmer temperatures and higher rainfall associated with climate change — coupled with the loss of predators — are bound to make the rodent problem worse, with calamitous implications.

As much as weather changes can drive changes in species, so does altering the landscape for new farms and new cities. In fact, researchers attribute a full 30% of emerging contagion to what they call “land use change.”

As the global population surges to 10 billion over the next 35 years, and the capacity to farm food is stressed further again by the warming climate, the demand for land will only get more intense.

Already, more than one-third of the planet’s land surface, and three-quarters of all of its fresh water, go toward the cultivation of crops and raising of livestock. These are the places where infectious diseases spread most often.

The U.S. Centers for Disease Control and Prevention says that fully three-quarters of all new viruses have emerged from animals

Almost every major epidemic we know of over the past couple of decades — SARS, COVID-19, Ebola and Nipah virus — jumped to people from wildlife enduring extreme climate and habitat strain, and still, “we’re naive to them,” she said. “That puts us in a dangerous place.”

A 2008 study in the journal Nature found nearly one-third of emerging infectious diseases over the past 10 years were vector-borne, and that the jumps matched unusual changes in the climate

Ticks and mosquitoes now thrive in places they’d never ventured before. As tropical species move northward, they are bringing dangerous pathogens with them.

by 2050, disease-carrying mosquitoes will ultimately reach 500 million more people than they do today, including some 55 million more Americans.

In 2013, dengue fever — an affliction affecting nearly 400 million people a year, but normally associated with the poorest regions of Africa — was transmitted locally in New York for the first time.

“The long-term risk from dengue may be much higher than COVID,

only 15% of the planet’s forests remain intact. The rest have been cut down, degraded or fragmented to the point that they disrupt the natural ecosystems that depend on them.

it’s only a matter of time before other exotic animal-driven pathogens are driven from the forests of the global tropics to the United States or Canada or Europe because of the warming climate.

it will also shape how easily we get sick. According to a 2013 study in the journal PLOS Currents Influenza, warm winters were predictors of the most severe flu seasons in the following year

Even harsh swings from hot to cold, or sudden storms — exactly the kinds of climate-induced patterns we’re already seeing — make people more likely to get sick.

The chance of a flu epidemic in America’s most populated cities will increase by as much as 50% this century, and flu-related deaths in Europe could also jump by 50%.

Slow action on climate has made dramatic warming and large-scale environmental changes inevitable, he said, “and I think that increases in disease are going to come along with it.”

By late 2018, epidemiologists there were bracing for what they call “spillover,” or the failure to keep a virus locally contained as it jumped from the bats and villages of Yunnan into the wider world.

In late 2018, the Trump administration, as part of a sweeping effort to bring U.S. programs in China to a halt, abruptly shut down the research — and its efforts to intercept the spread of a new novel coronavirus along with it. “We got a cease and desist,” said Dennis Carroll, who founded the PREDICT program and has been instrumental in global work to address the risks from emerging viruses. By late 2019, USAID had cut the program’s global funding.

The loss is immense. The researchers believed they were on the cusp of a breakthrough, racing to sequence the genes of the coronaviruses they’d extracted from the horseshoe bat and to begin work on vaccines.

They’d campaigned for years for policymakers to fully consider what they’d learned about how land development and climate changes were driving the spread of disease, and they thought their research could literally provide governments a map to the hot spots most likely to spawn the next pandemic.

They also hoped the genetic material they’d collected could lead to a vaccine not just for one lethal variation of COVID, but perhaps — like a missile defense shield for the biosphere — to address a whole family of viruses at once

Carroll said knowledge of the virus genomes had the potential “to totally transform how we think about future biomedical interventions before there’s an emergence.

PREDICT’s staff and advisers have pushed the U.S. government to consider how welding public health policy with environmental and climate science could help stem the spread of contagions.

Since Donald Trump was elected, the group hasn’t been invited back.

What Daszak really wants — in addition to restored funding to continue his work — is the public and leaders to understand that it’s human behavior driving the rise in disease, just as it drives the climate crisis

“We turn a blind eye to the fact that our behavior is driving this,” he said. “We get cheap goods through Walmart, and then we pay for it forever through the rise in pandemics. It’s upside down.”

time is running out for humans to learn from these temperature-sensitive microbes. As the climate changes, she said, “we are likely to be losing many of these interactions” before they can be documented.

Within another two million to three million years, Dr. O’Leary said, the first members of modern placental orders appeared in such profusion that researchers have started to refer to the explosive model of mammalian evolution

Although some small primitive mammals had lived in the shadow of the great Cretaceous reptiles, the scientists could not find evidence supporting an earlier hypothesis that up to 39 placental mammalian lineages survived to enter the post-extinction world. Only the stem lineage to Placentalia, they said, appeared to hang on through the catastrophe, generally associated with climate change after an asteroid crashed into Earth.

the “power of 4,500 characters” enabled the scientists to look “at all aspects of mammalian anatomy, from the skull and skeleton, to the teeth, to internal organs, to muscles and even fur patterns” to determine what the common ancestor possibly looked like.

this formidable new systematic data-crunching capability might reshape mammal research but that it would probably not immediately resolve the years of dispute between fossil and genetic partisans over when placental mammals arose. Paleontologists looking for answers in skeletons and anatomy have favored a date just before or a little after the Cretaceous extinction. Those who work with genetic data to tell time by “molecular clocks” have arrived at much earlier origins.

the post-Cretaceous date for the placentals “will surely be controversial, as this is much younger than estimates based on molecular clocks, and implies the compression of very long molecular branches at the base of the tree.”

The modern right to asylum has roots in the aftermath of World War I and the Russian Revolution.

Mr Biju, of the University of Delhi, is known as The Frog Man in India, for discovering 89 of the country's 350 or so frog species.

It has changed from Polypedates jerdonii - named after Thomas Jerdon, the British zoologist that collected the previously only known specimens in 1870 - to Frankixalus jerdonii, after herpetologist Franky Bossuyt - Mr Biju's adviser when he studied at Vrije Universiteit in Brussels, Belgium.

Nationalism, on the other hand, is inseparable from the desire for power. The abiding purpose of every nationalist is to secure more power and more prestige, not for himself but for the nation or other unit in which he has chosen to sink his own individuality.

Nationalism is antithetical to America’s founding creed (“All men are…”) and contrary to the principles of a multiethnic, multiracial democracy. As with all radical, racially based dogmas, it countenances, indeed promotes, ends-justify-the-means politics, seeks to discredit the free press, and traffics in lies both big and small.

I tend to think that the last explanation is the right one, but it hardly matters. What does matter is that Trump is normalizing a hateful political philosophy that is contrary to our deepest-held beliefs. He fuels divisions and anger, and in doing so, fails in his most sacred obligation — to defend the most diverse democracy the planet has ever known and to protect the institutions that secure our freedoms.

The third take on Trump’s nationalist lingo is the simplest: He knows exactly what it means, his base knows exactly what he means and he knows the strongest bond with followers is xenophobia.

Another explanation is the cynical one, advanced most clearly by the former (briefly) communications director Anthony Scaramucci. He insisted on CNN on Wednesday morning, “No, I’m not a nationalist. He’s not a nationalist. He’s saying he’s a nationalist because he wants you to be upset about it, but he’s really not a nationalist.” In other words, Trump supposedly is smart enough to know what “nationalist” means, but he is falsely associating himself with the term

One has us believe that Trump is an empty-headed dolt who has no idea what he is saying. He either ignored Bannon or forgot what he said. Like a child who doesn’t know what a “bad word” really means, he says it simply because it is socially forbidden (“we’re not supposed to use that word”)

So back to Trump. Three theories emerged to explain Trump’s nationalist utterance.

President Trump declared at a rally in Houston, “You know, they have a word, it sort of became old-fashioned, it’s called a nationalist, and I say, really, we’re not supposed to use that word. You know what I am? I’m a nationalist.” No sooner had he uttered the words than the scramble to analyze Trump’s motives began.

The first traces of the Nubian kingdom called Kush date to roughly 2,000 B.C. Egyptians conquered parts of the Kushite Kingdom for a few hundred years, and around 1,000 B.C., the Egyptians appear to have died, left, or mixed thoroughly with the local population. At 800 B.C., Kushite kings, also known as the black pharaohs, took over Egypt for a century—two cobras decorating the pharaohs’ crowns signified the unification of kingdoms. And somewhere around 300 A.D., the Kushite empire began to fade away.

A woman’s skull half coated with termite-riddled dirt rests on a wooden table. Smith beams and locates an amulet the size of his fist that he found beside this skeleton. The amulet is shaped like a scarab beetle, a common symbol of rebirth in Egypt, but the insect bears a man’s head. “This is very unusual,” Smith says. He laughs as he paraphrases hieroglyphics etched into the scarab’s underside: “On the day of judgment, let my heart not testify against me.”

“This period has been burdened by racist colonial interpretations assuming that Nubians were backwater and inferior and now we can tell the story of this remarkable civilization,” he adds

When ancient Egyptians conquered the region, they identified Jebel Barkal as the residence of the god Amun, who was believed to help renew life each year when the Nile flooded. They carved a temple into its base, and illustrated the walls with gods and goddesses. And when ancient Nubians regained control, they converted the holy mountain into a place for royal coronations, and constructed pyramids for royalty beside it.

The group has previously estimated that, in the Americas, nature itself—animals, plants, soil, water, all of it—is worth about twenty-four trillion dollars to us, an implausibly specific figure that makes the costs of degradation both more and less concrete.

“I think fundamentally we’ve got to get the message across that this is a crisis for humanity that could signal the end of human civilization as we know it. It’s not about animals somewhere off in the Arctic. It’s about the life that we lead, and whether we can keep leading it, and the chaos and violence that could ensue if we don’t do something immediately.”

“Even as someone who is basically an alarmist, it seemed really up in your face,” Wallace-Wells said of the group’s name and messaging. “But I also think, like, you kind of can’t argue with the results.”

Extinction Rebellion considers climate change and looming mass extinctions as intersecting but separate and potentially competing issues. In a statement last week, in response to the I.P.B.E.S. report, the group said that “too much of the focus has been on greenhouse gases and climate change. We also face an ecological crisis—the sixth mass extinction—which is as dangerous for our planet as climate change.” Jonathan Franzen said much the same, in this magazine, in 2015, describing climate change as a “usefully imponderable” problem compared to the threat of mass extinctions.

“There’s places where you’re losing habitat because temperatures are increasing, climate ranges are shifting north,

One third of the planet right now is in production of agriculture, and only about half of that is actually agriculture that has any kind of mind for the wildlife-habitat benefits that could be provided by just doing things slightly differently.”

“We’re trying to convince folks that, like, if we save nature, we save ourselves,” he continued. “If you have healthy habitats, we have healthy wildlife populations with clean water—all of that can help reduce emissions.”

Environmental groups insist that the sage grouse, just one of the countless bird species now thought to be at risk, really matters, and not only because undermining protections for it would be a boon for the fossil-fuel industries.

“It’s not just the sage grouse, right?” O’Mara said. “It’s the pronghorn. It’s the pygmy rabbit, the sagebrush vole. There’s a series of smaller species and bigger species that—if the sage grouse is healthy, that means the bigger ecosystem is doing pretty well. There’s three hundred and fifty other species that are likely doing O.K. if this one indicator species is doing O.K.”

the reality is that you have folks in both parties that deeply care about wildlife.”

We could all be doing more, but there’s maybe no greater separation between Democrats and Republicans today than on climate and pollution.”

Unlike climate change, the extinction crisis offers no clear targets to race toward or timelines to stick to. But addressing both will require, instead, a million revolutions, large and small, in the way we interact with and think about the natural world.

In the Netherlands, 400 more people died in the next-to-last week of July than normally would have during a typical summer week, the country’s statistics agency said Friday

On the other side of the planet, a heat wave in Japan stretched from July 29 to Aug. 4 and killed at least 57 people, while more than 18,000 others were taken to hospitals, with 100 in serious condition

NHK reported that 45 people in Tokyo had died in a week because of the heat.

A 2008 study by the Centers for Disease Control and Prevention found that extreme heat events “are the most prominent cause of weather-related human mortality in the U.S., responsible for more deaths annually than hurricanes, lightning, tornadoes, floods, and earthquakes combined.”

Climate change would cause illnesses such as asthma and hay fever to become more severe, while wildfires and pollution also posed a risk to respiratory health. Rising temperatures would alter the geographic distribution of disease-carrying insects and pests, endangering new populations.

“Climate change is a public health crisis,” Vijay Limaye told The Post. “The science is really strong in telling us that with climate change accelerating, we expect heat waves to be more frequent, more intense and longer.”

“As a nation and as a globe, we are not prepared to confront an ever-mounting heat risk in terms of our health,” he said. For example, while air conditioning was known to save lives, Limaye warned that increased reliance on the technology could have a harmful long-term effect if the energy used for cooling continued to come from fossil fuels.

Rhode Island is “the first state in the Lower 48 whose average temperature rise has eclipsed 2 degrees Celsius. Other parts of the Northeast — New Jersey, Connecticut, Maine and Massachusetts — trail close behind."

 “Today, more than 1 in 10 Americans — 34 million people — are living in rapidly heating regions, including New York City and Los Angeles. Seventy-one counties have already hit the 2-degree Celsius mark.”

it is higher winter temperatures that have made New Jersey and nearby Rhode Island the fastest warming of the Lower 48 states.” 

“The average New Jersey temperature from December through February now exceeds 0 degrees Celsius, the temperature at which water freezes. That threshold, reached over the past three decades, has meant lakes don't freeze as often, snow melts more quickly, and insects and pests don't die as they once did in the harsher cold.”

"By 2030, sea level rise will flood 605 buildings six times a year, according to the Rhode Island Coastal Resources Management Council’s executive director, Grover Fugate.

Many scientists have been warning us for years, citing a pace of extinctions far beyond the historical "background" rate. Yet critics have argued that's based on inadequate data, preserving doubt about the scope of modern wildlife declines. To see if such doubt is justified, the 2015 study compared a conservatively low estimate of current extinctions with an estimated background rate twice as high as those used in previous studies. Despite the extra caution, it still found species are disappearing up to 114 times more quickly than they normally do in between mass extinctions

six important things to know about life in the sixth mass extinction:

1. This isn't normal.

"Even under our assumptions, which would tend to minimize evidence of an incipient mass extinction, the average rate of vertebrate species loss over the last century is up to 114 times higher than the background rate," the study's authors write. "Under the 2 E/MSY background rate, the number of species that have gone extinct in the last century would have taken, depending on the vertebrate taxon, between 800 and 10,000 years to disappear.

ndicating that a sixth mass extinction is already under way."

2. Space is at a premium.

The No. 1 cause of modern wildlife declines is habitat loss and fragmentation, representing the primary threat for 85 percent of all species on the IUCN Red List. That includes deforestation for farming, logging and settlement, but also the less obvious threat of fragmentation by roads and other infrastructure.

3. Vertebrates are vanishing.

The number of vertebrate species that have definitely gone extinct since 1500 is at least 338,

Even under the most conservative estimates, the extinction rates for mammals, birds, amphibians and fish have all been at least 20 times their expected rates since 1900, the researchers note (the rate for reptiles ranges from 8 to 24 times above expected). Earth's entire vertebrate population has reportedly fallen 52 percent in the last 45 years alone

he threat of extinction still looms for many — including an estimated 41 percent of all amphibian species and 26 percent of mammals.

4. It's probably still worse than we think.

The 2015 study was intentionally conservative, so the actual rate of extinctions is almost certainly more extreme than it suggests

The study also focuses on vertebrates, which are typically easier to count than smaller or subtler wildlife like mollusks, insects and plants. As another recent study pointed out, this leaves much of the crisis unexamined. "Mammals and birds provide the most robust data, because the status of almost all has been assessed," the authors of that study write. "Invertebrates constitute over 99 percent of species diversity, but the status of only a tiny fraction has been assessed, thereby dramatically underestimating overall levels of extinction.

we may already have lost 7 percent of [contemporary] species on Earth

5. No species is safe.

"If it is allowed to continue, life would take many millions of years to recover, and our species itself would likely disappear early on," says Gerardo Ceballos of the Universidad Autónoma de México, lead author of the 2015 study. "We are sawing off the limb that we are sitting on,"

6. Unlike an asteroid, we can be reasoned with.

some of his work remained unsurpassed until the 19th century.

But he is, of course, most outstanding as a philosopher.

Within the Academy, however, relations seem to have remained cordial. Aristotle always acknowledged a great debt to Plato; he took a large part of his philosophical agenda from Plato, and his teaching is more often a modification than a repudiation of Plato’s doctrines.

Aristotle was born on the Chalcidic peninsula of Macedonia, in northern Greece.

Many of Plato’s later dialogues date from these decades, and they may reflect Aristotle’s contributions to philosophical debate at the Academy.

It is possible that two of Aristotle’s surviving works on logic and disputation, the Topics and the Sophistical Refutations, belong to this early period.

During Aristotle’s residence at the Academy, King Philip II of Macedonia (reigned 359–336 bce) waged war on a number of Greek city-states.

His writings in ethics and political theory as well as in metaphysics and the philosophy of science continue to be studied,

When Plato died about 348, his nephew Speusippus became head of the Academy, and Aristotle left Athens.

While in Assus and during the subsequent few years when he lived in the city of Mytilene on the island of Lesbos, Aristotle carried out extensive scientific research, particularly in zoology and marine biology.

The scope of Aristotle’s scientific research is astonishing.

The myriad items of information about the anatomy, diet, habitat, modes of copulation, and reproductive systems of mammals, reptiles, fish, and insects are a melange of minute investigation and vestiges of superstition.

In 343 or 342 Aristotle was summoned by Philip II to the Macedonian capital at Pella to act as tutor to Philip’s 13-year-old son, the future Alexander the Great.

By 326 Alexander had made himself master of an empire that stretched from the Danube to the Indus and included Libya and Egypt.

Most of Aristotle’s surviving works, with the exception of the zoological treatises, probably belong to this second Athenian sojourn.

Aristotle’s works, though not as polished as Plato’s, are systematic in a way that Plato’s never were.

Aristotle divided the sciences into three kinds: productive, practical, and theoretical.

When Alexander died in 323, democratic Athens became uncomfortable for Macedonians, even those who were anti-imperialist.

Aristotle’s writings fall into two groups: those that were published by him but are now almost entirely lost, and those that were not intended for publication but were collected and preserved by others.

Time cannot be composed of indivisible moments, because between any two moments there is always a period of time.

Motion (kinesis) was for Aristotle a broad term, encompassing changes in several different categories.

For Aristotle, extension, motion, and time are three fundamental continua in an intimate and ordered relation to each other.

Change, for Aristotle, can take place in many different categories.
