"Today's real borders are not between nations, but between powerful and powerless, free and fettered, privileged and humiliated. Today, no walls can separate humanitarian or human rights crises in one part of the world from national security crises in another."

"When Boswell confessed to Johnson that he feared some things he was entering in his journal were too small, the latter advised him that nothing is too small for so small a creature as man."

"When events and circumstances which have influenced us pass away in the course of time, we are unable to bring back and renew the particular mood or state of feeling which they aroused in us: but we can remember what we were led to say and do in regard to them; and thus form, as it were, the result, expression and measure of those events. We should, therefore, be careful to preserve the memory of our thoughts at important points in our life; and herein lies the great advantage of keeping a journal."

"The longer I live, the more urgent it seems to me to endure and transcribe the whole dictation of existence up to its end, for it might just be the case that only the very last sentence contains that small and possibly inconspicuous word through which everything we had struggled to learn and everything we had failed to understand will be transformed suddenly into magnificent sense."

"If your journal consists of the best moments of your life and reading, then rereading it will be like walking a high mountain trail that goes from peak to peak without the intervening descent into the trough of routine. Just reading such a journal of high points will tighten your strings and raise your pitch."

"Diaries have been a rich source of material for me. Not the events recorded in such journals, but the mental attitude, the moral standards, and the feelings of people at the time. It is all right to imagine, but the imagination must have a takeoff point, it must have a basis in fact."

"For practical rules for the culture of the intellect perhaps none can be given that are good for all but there are two expedients that may do such good service to very many young men that I will venture to name them."

"DIARY, n. A daily record of that part of one's life, which he can relate to himself without blushing."

"The diary ... is the unfathomable document of a life never lived, the book of a life in whose time everything that we experienced inadequately is transformed into experience perfected."

"The elephant bird and the giant lemurs, along with most of the other large animals of Madagascar, suddenly vanished about 1.500 years ago - precisely when the first humans set foot on the island."

"At the time of the Cognitive Revolution, the planet was home to about 200 genera of large terrestrial mammals weighing over fifty kilograms. At the time of the Agricultural Revolution, only about one hundred remained. Homo sapiens drove to extinction about half of the planet's big beasts long before humans invented the wheel, writing or iron tools."

"The extinction of the Australian Megafauna was probably the first significant mark Homo sapiens left on our planet."

"Since 1970, overall numbers are down by 69%. Livestock and the human beings who farm them now account for 96% of all the mammals on Earth. The Sumatran tiger, the Bornean orangutan and the hellbender salamander are among the million animal and plant species judged perilously close to extinction."

"The introduction of a new alpha predator can have dramatic effects, even causing cascades of extinction. This is not necessarily because the alpha predators overhunt or are even in the least bit maladaptive; this is simply the nature of alpha predators and how they relate in any given ecology. When humans came to Australia and the Americas, they were as harmless as wolves, lions, or any other big mammalian predator. Their presence caused cascades of changes throughout the ecosystem. Given that it was also a period of major climate change, a great number of species that were already under stress adapting to the new climate were tipped over the edge into extinction by the further ecological changes created by the adaptation of a new alpha predator. Our ancestors were hardly noble savages; but neither were they bloodthirsty killers bent on the destruction of all life on earth. They were animals, like any other."

"The human race currently consumes some 40% of the earth’s photosynthetic capacity. This monopoly on the earth’s resources is having a devastating effect. We are seeing the extinction of some 140 species every day, some thousands of times higher than the normal background rate. Today, right now, we are seeing extinction rates unparalleled in the history of the earth. We are undeniably in the midst of the seventh mass extinction event in the history of the earth — the Holocene Extinction. Unlikely previous extinction events, however, this one is driven by a single species. This is the true danger of overpopulation, not our inability to feed a growing population. As much as we would deny it, we depend on the earth to live. Dwindling biodiversity threatens the very survival of our species. We are literally cutting the ground out from under our feet. Increasing food production only increases the population; our current attitudes about food security has locked us into what Daniel Quinn called a “Food Race,” by comparison to the Arms Race of the Cold War."

"The Brontosaurus had a brain no bigger than a crisp. The Dodo had a stammer, and the Mammoth had a lisp. The Auk was just too awkward. Now they're none of them alive; Each one, like Man, had shown himself unfitted to survive. Their story points a moral; now it's we who wear the pants. The extinction of these species holds a lesson for us ants."

"It is clear that only a giant change in human culture can significantly limit the extinction crisis. Humanity must face the need to reduce birth rates further, especially among the overconsuming wealthy and middle classes. In addition, a reduction of wasteful consumption will be necessary, accompanied by a transition away from environmentally malign technological choices such as private automobiles, plastic everything, and treating billionaires to space tourism. Otherwise growthmania will win; the human enterprise will not undergo the needed shrinkage, but will continue to expand, destroying most of biodiversity and further wrecking the life-support systems of humanity until global civilization collapses"

"Capitalism is not necessarily more immoral than previous social systems with regard to cruelty to humans and the gratuitous destruction of nature. As a mode of production and a social system, however, capitalism requires people to be destructive of the environment. Three destructive aspects of the capitalist system stand out when we view this system in relation to the extinction crisis: 1) capitalism tends to degrade the conditions of its own production; 2) it must expand ceaselessly in order to survive; 3) it generates a chaotic world system, which in turn intensifies the extinction crisis."

"The beauty and genius of a work of art may be reconceived, though its first material expression be destroyed; a vanished harmony may yet again inspire the composer; but when the last individual of a race of living beings breathes no more, another heaven and another earth must pass before such a one can be again."

"Let's not be too quick to blame the human race for everything. We must remember that a great many species of animals became extinct before man ever appeared on earth. At the same time it is probably true that when two husky representatives of Homo sapiens, with clubs, corner the last two birds of a species, no matter how far they have or have not evolved, both the phylogeny and the ontogeny of those birds are, to all intents and purposes, over."

"…we are fighting to leave as much biological heritage as we can for nature to do whatever it will do when we fall on our own sword and stop being the worst plague that ever existed—which is sadly what we are, collectively, in spite of the good and beautiful things that humans are also capable of."

"Life has now entered a sixth mass extinction. This is probably the most serious environmental problem, because the loss of a species is permanent, each of them playing a greater or lesser role in the living systems on which we all depend . The species extinctions that define the current crisis are, in turn, based on the massive disappearance of their component populations, mostly since the 1800s. The massive losses that we are experiencing are being caused, directly or indirectly, by the activities of Homo sapiens. They have almost all occurred since our ancestors developed agriculture, some 11,000 y ago. At that time, we numbered about 1 million people worldwide; now there are 7.7 billion of us, and our numbers are still rapidly growing. As our numbers have grown, humanity has come to pose an unprecedented threat to the vast majority of its living companions."

"Much less frequently mentioned are, however, the ultimate drivers of those immediate causes of biotic destruction, namely, human overpopulation and continued population growth, and overconsumption, especially by the rich. These drivers, all of which trace to the fiction that perpetual growth can occur on a finite planet, are themselves increasing rapidly."

"Global biodiversity decline is best understood as growing numbers of people and their rapidly expanding economic support systems crowding out other species. Conservation biologists standardly list five main direct drivers of biodiversity loss: habitat loss, of species, pollution, invasive species, and climate change. The ' found that in recent decades habitat loss was the leading cause of terrestrial , while overexploitation () was the most important cause of marine losses. All five direct drivers are important, on land and at sea, and all are made worse by larger and denser human populations."

"EXTINCTION, n. The raw material out of which theology created the future state."

"We have since built museums to celebrate the past, and spent decades studying prehistoric lives. And if all this has taught us anything, it is this: no species lasts forever."

"The human species is driving itself [at] full speed into an evolutionary dead-end. We are destroying the planet and everything we do murders animals and dismantles ecosystems. We have lost our moral compass. We think in terms of profit and power rather than ethics and compassion. We no longer have reverence for life or any sense of connection with the natural world. We see ourselves as conquerors of nature rather than citizens of a vast biocommunity. We are technologically sophisticated and morally stunted. We have no conception of the importance of nonhuman life forms in sustaining ecosystems and no sensitivity to the inherent value of species outside of our exploitative purposes. We fail to realize that what we do to animals and the earth, we do to ourselves. And all the while, we live in a fantasy land of entertainment and distractions whereby we focus more on the sex lives and surgical makeovers of movie stars than the most consequential changes unfolding in this planet in the last sixty-five million years."

"While certainly no cultures, peoples, and social systems have been as devastating to animals and the environment as modern capitalism, there was no Edenic time, no Golden Era, when humans lived in peace and harmony with one another, other species, and their natural surroundings. Problems like species extinction, resource depletion, desertification, and overall mindless destruction of life and ecosystems did not originate in European modernity but rather have deep roots in antiquity and prehistory."

"This time it is we who are the meteor crashing into the earth, and we keep crashing and crashing and crashing, never allowing the planet to recover. We are a meteor storm that continuously, repetitively keeps slamming into the planet, precluding adaptation and blocking recovery. If we cannot learn how to live on this planet and harmonize our existence with other species and the biocommunity as a whole, then, frankly, we have no right to live at all. If we can only exploit, plunder, and destroy, then surely our demise is for the greater good. Whereas worms, pollinators, dung beetles, and countless other species are vital to a flourishing planet, Homo sapiens is the one species the earth could well do without."

"It is noteworthy that human concern about human extinction takes a different form from human concern (where there is any) about the extinction of non-human species. Most humans who are concerned about the extinction of non-human species are not concerned about the individual animals whose lives are cut short in the passage to extinction, even though that is one of the best reasons to be concerned about extinction (at least in its killing form). The popular concern about animal extinction is usually concern for humans –- that we shall live in a world impoverished by the loss of one aspect of faunal diversity, that we shall no longer be able to behold or use that species of animal. In other words, none of the typical concerns about human extinction are applied to non-human species extinction."

"We are now living in the era of the sixth extinction crisis in the history of the planet, the last one occurring 65 million years ago when a meteor struck the Gulf of Mexico and annihilated half of existing species including the dinosaurs. Unlike the last five, however, the sixth extinction crisis is caused by human activity."

"[The Sixth Extinction] did not happen yesterday because we suddenly became aware of the dangers of global warming. It began 50,000 years ago when a relatively hairless primate stumbled out of equatorial Africa and began wiping out the megafauna of the time. Wherever this creature (our ancestor) went, their arrival was followed by large die-outs of megafauna. Primitive hominids were well-organized, efficient, slaughter crews. As they advanced, the mammoth, sabre-toothed cats, cave bears, giant sloths, camels, horses, and wholly rhinos fell to their stone weapons and deliberately set fires. The extinction of all of these great mega-species is directly attributable to "primitive" human hunters. The hunting down of the mega-fauna was followed by the advent of agriculture and the domestication of selected animals. Domesticated cows, goats, sheep, and pigs grew in numbers and denuded large areas of grasslands. Irrigation systems began to toxify land. Then agriculture was followed by industrial activities, and finally, by the burning off of vast amounts of fossil fuels."

"[We] cannot bring back species from extinction… We are still driving 150 species to oblivion daily… Collapse will not change anything in our attitudes. As long as humans remain genetically identical to who they are today, I’m afraid they will collapse again, and again, after this coming collapse, and probably risk complete extinction. This is not speculation, but simply looking at historical evidence: over thousands of years we have collapsed pretty much constantly—anthropologists have documented the collapse of more than 82 (!!!) civilisations. We are now at the stage of a systemic, global collapse because we are one, united global economic machine that has used up everything on the planet. Our species is wired for growth, and we are designed to go through boom-and-bust cycles. What comes after the next bust will be a significantly smaller civilisation… There will be another, smaller boom, then collapse again. With each collapse many… “species” risk disappearance."

"[The transition from Australopithecus to Homo] marked the shift from hominins that depend heavily on plants to ones that depend more on meat… Being a good predator is a general feature of our genus."

"Since after extinction no one will be present to take responsibility, we have to take full responsibility now."

"Long before the first kings, priests, or merchants inscribed their deeds in clay or papyrus, humans were altering ecosystems simply by moving through them. The great dispersal of our species out of Africa, beginning roughly 60,000–70,000 years ago, reshaped continents. Wherever humans arrived, waves of extinctions followed: giant marsupials in Australia, mammoths and mastodons across the Americas, enormous birds in New Zealand and Madagascar. These losses were not caused by Western civilization, or any civilization at all, but by small bands of foragers equipped with nothing more than stone tools, spears, and fire."

"Species are threatened because of over-exploitation, habitat destruction, climate change, and so on. Efforts to reverse, or stall, a decline in population would have to go on indefinitely (i.e. would have to be sustainable) unless all of the factors involved in the decline are removed. But modernity is the cause of all of those factors so conservation will inevitably fail until modernity ends (and then there would be no conservation efforts with humans needing to be more involved in saving their own lives)."

"Given that human societies, before they migrated out of Africa, in significant numbers were as close to sustainable as we’re likely to get, that is the best we can hope for, at least for future generations. But let’s not pretend that there is some sustainable way of life for future humans (our species) that we could hope they would attain. We’ve done that experiment. Humans didn’t live in harmony with nature. They got close, but ultimately couldn’t restrain themselves from causing some extinctions and then many more extinctions when they followed their migratory traits."

"Moreover, we have unleashed a mass extinction event, the sixth in roughly 540 million years, wherein many current life forms could be annihilated or at least committed to extinction by the end of this century."

"Indeed, in the long run, extinctions of species are as inevitable as the deaths of individual animals, and it may be that the causes of extinctions are as varied as the causes of individual deaths. A wave of extinctions—a sudden diminution in the number of species—is analogous to a sudden big drop in the size of a human population, an event that deserves to be explained even though the individual people would inevitably have died sooner or later anyway. Catastrophes in human populations have many causes: war, famine, and pestilence are the possibilities that first spring to mind. There may be equally many causes for evolutionary catastrophes, as waves of extinctions could well be called. Another possibility, however, is that extinctions come in waves that are part of a recurring cycle. It would then be the cycle itself, rather than each individual wave in the cycle, that would need to be explained. If there is such a cycle, it presumably follows a cycle in the inorganic world, such as cyclic climactic changes."

"In what year will the human population grow too large for the Earth to sustain? The answer is about 1970, according to research by the . In 1970, the planet's 3 and a half billion people were . But on this New Year's Day, the population is 8 billion. Today, wild plants and animals are running out of places to live."

"Finding out that 1 million species face extinction without radical corrective changes in human behavior is akin to finding out you have a fatal disease. One day you have a thousand problems; the next, you have just one. Nothing in today’s headlines compares to the catastrophic potential posed by climate change and the decimating effects of careless consumerism around the globe."

"Extinction rates are up 100–1,000 times the background rate—and possibly higher [and] we are currently witnessing the highest extinction rate since the Chicxulub impact that took out dinosaurs 65 million years ago. […] Annual population declines tend to be in the 1–2% range among mammals, birds, fish, and insects, accumulating to average declines of more than half in less than half a century."

"We have loads of evidence for rapidly declining ecological health, in virtually every measure. Accelerating biodiversity loss rates are consistent with the initiation of a sixth mass extinction. Modernity has every appearance of being grossly unsustainable."

"The scale and rapidity of these changes create credible concern that we are witnessing (causing) the beginning of a sixth mass extinction. Earth has been slapped hard, out of nowhere, at alarming speed. Although the evidence of its reeling is all around us, it is far too soon to appreciate the severity of what we have set in motion. A hard slap on the face looks red in the moment, but later appears bruised and might turn into a black eye. We are currently only seeing the instant, real-time response and not the protracted bruising to follow, which will take a long time to play out as many wild populations glide toward extinction and domino-effect failures pile up. […] Ecological collapse is extremely dangerous to large, complex, hungry, high-maintenance animals like humans. We are not likely to fare well in a sixth mass extinction of our own making."

"Having initiated a sixth mass extinction, carried out by access to energy, continued powering of modernity (via electricity, for instance) most likely means compounding ecological harm, piling up accelerating extinctions, under which conditions high-maintenance humans are unlikely to fare well."

"Compared to the human accomplishment of driving the globe into a sixth mass extinction... elephants are shamefully worthless and lacking a final goal, as are all 10 million species on the planet—including us."

"…because of megafauna extinctions, being the only species to use fire, and the fact that an ability for symbolic representation and complex speech might be the recipe for a runaway species capable of rapid cultural evolution and technology development out of step with the rest of the community of life, and therefore maladapted to long-term co-existence in ecological relationship. If it looks like we’re winning the “battle against nature” right now, that’s actually what losing looks like."

"Our fossil fuel bonanza has left our ecosystem in a perilous state. We have destroyed vast forests and habitat, polluted water and soil, kicked off a rapid climate trend that natural systems may not adapt to quickly enough, and basically overrun the planet. […] 96% of mammal mass on the planet is now in the form of humans and our livestock, leaving a paltry 4% of wild mammals—land and sea. Roughly 70% of vertebrate numbers have vanished since 1970 (undoubtedly a higher fraction if the survey had started in 1700). Forests are also way down."

"If we do not devise an intentional method of suppressing human exceptionalism, we will foul the nest to the point of self-harm (sound familiar?) by precipitating an ecosystem collapse. In this unfortunate, unwitting undoing, we will have answered evolution’s question: how far can intelligence be pushed as a survival strategy before it is self-terminating? Or worse than self-terminating: taking numerous other innocent species down with us."
