"[[w: Boycott, Divestment and Sanctions|The BDS [Boycott, Divestment and Sanctions] movement]] was launched in 2005 by representatives of Palestinian civil society. They called upon “international civil society organizations and people of conscience all over the world to impose broad boycotts and implement divestment initiatives against Israel similar to those applied to South Africa in the apartheid era …” This call for BDS specified that “these non-violent punitive measures” should last until Israel fully complies with international law..."
"All infections, of whatever type, with no exceptions, are products of parasitic beings; that is, by living organisms that enter in other living organisms, in which they find nourishment, that is, food that suits them, here they hatch, grow and reproduce themselves."
"What keeps snails and flukes apart in evolution is their divergent future interests, and this is because they do not share reproductive propagules. What keeps host genes together with host genes — and parasite genes together with parasite genes - is that they do share future interests. Parasites, then, have led us to the solution to the paradox of the organism. The genes in an organism share desiderata lists. And this is simply because they submit to the same meiotic lottery and possess the same stochastic gametic destiny."
"I cannot persuade myself that a beneficent and omnipotent God would have designedly created the Ichneumonidæ with the express intention of their feeding within the living bodies of Caterpillars, or that a cat should play with mice."
"The facts obtained in this study may possibly be sufficient proof of the causal relationship, that only the most sceptical can raise the objection that the discovered microorganism is not the cause but only an accompaniment of the disease [...] It is necessary to obtain a perfect proof to satisfy oneself that the parasite and the disease are [...] actually causally related, and that the parasite is the [...] direct cause of the disease. This can only be done by completely separating the parasite from the diseased organism [and] introducing the isolated parasite into healthy organisms and induce the disease anew with all its characteristic symptoms and properties."
"It is only within the present epoch, that physiology and chemistry have reached the point at which they could offer a scientific foundation to agriculture; and it is only within the present epoch, that zoology and physiology have yielded any very great aid to pathology and hygiene. But within that time, they have already rendered highly important services by the exploration of the phenomena of parasitism. Not only have the history of the animal parasites, such as the tapeworms and the trichina, which infest men and animals, with deadly results, been cleared up by means of experimental investigations [...] but the terrible agency of the parasitic fungi and of the infinitesimally minute microbes, which work far greater havoc among plants and animals, has been brought to light."
"To choose a rough example, think of a thorn which has stuck in a finger and produces an inflammation and suppuration. Should the thorn be discharged with the pus, then the finger of another individual may be pricked with it, and the disease may be produced a second time. In this case it would not be the disease, not even its product, that would be transmitted by the thorn, but rather the stimulus which engendered it. Now supposing that the thorn is capable of multiplying in the sick body, or that every smallest part may again become a thorn, then one would be able to excite the same disease, inflammation and suppuration, in other individuals by transmitting any of its smallest parts. The disease is not the parasite but the thorn. Diseases resemble one another, because their causes resemble each other. The contagion in our sense is therefore not the germ or seed of the disease, but rather the cause of the disease. For example, the egg of a taenia is not the product of a worm disease even though the worm disease may have been the cause, which first gave rise to the taenia in the intestinal contents—nor of the individual afflicted with the worm disease, but rather of the parasitic body, which, no matter how it may have come into the world at first, now reproduces itself by means of eggs, and produces the symptoms of the worm disease, at least in part. It is not the seed of the disease; the latter multiplies in the sick organism, and is again excreted at the end of the disease."
"This day relenting God Hath placed within my hand A wondrous thing; and God Be praised. At His command, Seeking His secret deeds With tears and toiling breath, I find thy cunning seeds, O million-murdering Death. I know this little thing A myriad men will save. O Death, where is thy sting? Thy victory, O Grave? [Poem he wrote following the discovery that the malaria parasite was carried by the amopheline mosquito]"
"Lately, however, on abandoning the brindled and grey mosquitos and commencing similar work on a new, brown species, of which I have as yet obtained very few individuals, I succeeded in finding in two of them certain remarkable and suspicious cells containing pigment identical in appearance to that of the parasite of malaria. As these cells appear to me to be very worthy of attention [...] I think it would be advisable to place on record a brief description both of the cells and of the mosquitos."
"After long pondering, I believe that I can define good and evil in terms to which even a biologist of the mechanical school can hardly take exception. At least, I fancy that I can do so for evil. The great evil of life is parasitism."
"The belief is growing on me that the disease is communicated by the bite of the mosquito [...] She always injects a small quantity of fluid with her bite—what if the parasites get into the system in this manner."
"Some species of carpenter ants infected with metacercariae of the fluke Brachylecithutn mosquensis, are more obese than noninfected ants and, unlike the latter, they do not conceal themselves but crawl on exposed surfaces where they are easily found by birds that are the next hosts of the fluke. This behaviour seems to be a remarkable example of an animal that sacrifices its life for its parasites. The 'sacrifice', of course, is induced by the parasite."
"I have failed in finding parasites in mosquitoes fed on malaria patients, but perhaps I am not using the proper kind of mosquito."
"I can think of a few microorganisms, possibly the tubercle bacillus, the syphilis spirochete, the malarial parasite, and a few others, that have a selective advantage in their ability to infect human beings, but there is nothing to be gained, in an evolutionary sense, by the capacity to cause illness or death. Pathogenicity may be something of a disadvantage for most microbes."
"Nowhere is it more true that "prevention is better than cure," than in the case of Parasitic Diseases."
"In this strange and apparently cruel operation one circumstance is truly remarkable. The larva of the Ichneumon, though every day, perhaps for months, it gnaws the inside of the caterpillar, and though at last it has devoured almost every part of it except the skin and intestines, carefully all this time it avoids injuring the vital organs, as if aware that its own existence depends on that of the insect upon which it preys!"
"Nearly all birds build nests of some kind in which to cradle their eggs and young. The cow-bird and cuckoo (European), however, are exceptions. These birds have the rather human practice of turning their cares and labours over to somebody else. They are loafers and parasites. They lay their eggs secretly in the nests of other birds, where their eggs are hatched and their young cared for by an alien mother. I have seen a mother song-sparrow hustling about among the shrubs and grasses for an hour at a time almost, gathering food for a young cow-bird nearly twice as big as she was, while her foundling sat phlegmatically at the foot of a tree chirping and fluttering its wings, and acting as a thankless and apparently bottomless receptacle for the morsel after morsel laboriously harvested for it by its tireless little foster-mother."
"Let me repeat that these parasitic insects comprise ten percent of all known animal species. How can this be understood? Certainly we give our infants the wrong idea about their fellow creatures in the world. Teddy bears should come with tiny stuffed bearlice; ten percent of all baby bibs and rattles sold should be adorned with colorful blowflies, maggots, and screw-worms. What kind of devil’s tithe do we pay? What percentage of the world’s species that are not insects are parasitic? Could it be, counting bacteria and viruses, that we live in a world in which half the creatures are running from—or limping from—the other half?"
"Fell Oestrus buries in her rapid course Her countless brood in stag, or bull, or horse; Whose hungry larva eats its living way, Hatch'd by the warmth, and issues into day."
"Whoever looks at the insect world, at flies, aphides, gnats and innumerable parasites, and even at the infant mammals, must have remarked the extreme content they take in suction, which constitutes the main business of their life. If we go into a library or newsroom, we see the same function on a higher plane, performed with like ardor, with equal impatience of interruption, indicating the sweetness of the act. In the highest civilization the book is still the highest delight."
"I hope no such planet exists, but consider one where slow, painful death from parasitism is universal. How would we talk about nature on such a planet? What kind of book would Thoreau have written there?"
"The insidious lethality of a parasitic wasp, the cruelty of a cat playing with a mouse – these are, after all, just the tip of the iceberg. To ponder natural selection is to be staggered by the amount of suffering and death that can be the price for a single, slight advance in organic design. And it is to realize, moreover, that the purpose of this "advance" – longer, sharper canine teeth in male chimpanzees, say – is often to make other animals suffer or die more surely. Organic design thrives on pain, and pain thrives on organic design."
"[The parasite that causes malaria] edges through the cells of the stomach wall of the mosquito and forms a cyst which grows and eventually bursts to release hundreds of "sporozoites" into the body cavity of the mosquito [...] As far as we can tell, the parasite does not harm the mosquito [...] It has always seemed to me, though, that these growing cysts [...] must at least give the mosquito something corresponding to a stomach-ache."
"The wing'd Ichneumon for her embryon young Gores with sharp horn the caterpillar throng. The cruel larva mines its silky course, And tears the vitals of its fostering nurse."
"There is an extremely thin line of demarcation between the ferment and the parasite."
"It is about the most awful thing you can imagine in terms of a non-fatal ailment. It's a parasitic disease and you know you've got it when at some point you develop a blister on your skin on your leg or your arm, and it's a burning blister and soon what emerges is a worm, and it's a worm that eventually, as it comes out, could be three-feet-long. It looks like a long strand of angel hair pasta and it's excruciatingly painful as it comes out. And the way it's transmitted is through drinking water. The worm, when it comes out, you've got that burning blister, your instinct is to want to immerse the skin in water. Well, when you do that, the worm puts out thousands and thousands of larvae that infects the drinking water. If anyone drinks the water, it gets into their system and a year later they develop a blister and out comes another worm."
"[A] major difficulty in the parasite's life is the return to water. It is, therefore, of particular interest that the parasite appears to affect the behaviour of its hosts, and 'encourages' it to return to water. The mechanism by which this is achieved is obscure, but there are sufficient isolated reports to certify that the parasite does influence its hosts, and often suicidally for the host [...] One of the more dramatic reports describes an infected bee flying over a pool and, when about six feet over it, diving straight into the water. Immediately on impact the gordian worm burst out and swam into the water, the maimed bee being left to die."
"The modern economy is structurally reliant on economic growth for its stability. [...] But question it we must. [...] No subsystem of a finite system can grow indefinitely – at least in physical terms. Economists have to be able to answer the question of how a continually growing economic system can fit within a finite ecological system. The only answer available is that growth in dollars must be 'decoupled' from growth in physical throughputs and environmental impacts. But [...] this hasn't so far achieved what's needed. There are no prospects for it doing so in the immediate future. And the sheer scale of decoupling required to meet the limits set out here (and stay within them in perpetuity while the economy keeps on growing) staggers the imagination. In short, we have no alternative but to question growth. The myth of growth has failed us."
"Decoupling growth from is the number one challenge facing governments in a world of rising numbers of people, rising incomes, rising consumption demands and the persistent challenge of poverty alleviation."
"The main challenges of our times are the rise in inequality and global warming. We must therefore implement international treaties enabling us to respond to these challenges and to promote a model for fair and sustainable development."
"When I use the term sustainable development – which I consider to be an oxymoron actually – I am trying to capture the meaning that most people seem to have. In so far as I can tell, people who use the term mean, essentially, that this would be a phase of development where they get to keep what they have but all the poor people can catch up. Or, they get to keep doing what they’ve been doing, but through the magic of technology they are going to cause less damage to the environment and use fewer resources. Either way you use the term, it is just a fantasy. Neither of those is possible – anymore."
"There was a strange aftertaste to many of the calls for grand social reform in 2020. As the coronavirus crisis overtook us, the left wing on both sides of the Atlantic, at least that part that had been fired up Jeremy Corbyn and Bernie Sanders, was going down to defeat. The promise of a radicalized and reenergized left, organized around the idea of the Green New Deal, seemed to dissipate amidst the pandemic. It fell to governments mainly of the center and the right to meet the crisis. They were a strange assortment. Jair Bolsonaro in Brazil and Donald Trump in the United States experimented with denial. For them climate skepticism and virus skepticism went hand in hand. In Mexico, the notionally left-wing government of Andrés Manuel López Obrador also pursued a maverick path, refusing to take drastic action. Nationalist strongmen like Rodrigo Duterte in the Philippines, Narendra Modi in India, Vladimir Putin in Russia, and Recep Tayyip Erdoğan in Turkey did not deny the virus, but relied on their patriotic appeal and bullying tactics to see them through. It was the managerial centrist types who were under most pressure. Figures like Nancy Pelosi and Chuck Schumer in the United States, or Sebastián Piñera in Chile, or Cyril Ramaphosa in South Africa, Emmanuel Macron, Angela Merkel, Ursula von der Leyen, and their ilk in Europe. They accepted the science. Denial was not an option. They were desperate to demonstrate that they were better than the 'populists.' To meet the crisis, very middle-of-the-road politicians ended up doing very radical things. Most of it was improvisation and compromise, but insofar as they managed to put a programmatic gloss on their responses—whether in the form of the EU's Next Generation program or Biden's Build Back Better program in 2020—it came from the repertoire of green modernization, sustainable development, and the Green New Deal."
"Climate change and biodiversity loss . . . pose an even greater existential threat [than the COVID-19 pandemic], to the extent that we have to put ourselves on what might be called a war-like footing. . . . Putting a value on carbon . . . [is] absolutely critical. . . . [W]e need a vast military style campaign to marshall the strength of the global private sector[, which has] trillions at its disposal . . . . [E]ach sector needs a clear strategy to speed up the process of getting innovations to market [and we] need to align private investment behind these industry strategies. . . . If we can develop a pipeline of many more sustainable and "bankable" projects, at a sufficient scale, it will attract greater investment. . . . CEOs and institutional investors have told me that alongside the promises countries have made, their nationally determined contributions, they need clear market signals, agreed globally, so that they have the confidence to invest without the goal posts suddenly moving. . . . [[wikipedia:Charles III#Natural_environment|[W]e are working]] to drive trillions of dollars in support of transition across ten of the most emitting and polluting industries [including] energy, agriculture, transportation, health systems and fashion. . . . I can only urge you, as the world’s decision-makers, to find practical ways of overcoming differences so we can all . . . rescue this precious planet and save the threatened future of our young people."
"If you want to contribute to the fight against global warming, live in a city in a high-rise apartment—where radiant heat seeps through walls into other people’s units, lowering heating costs—and commute by subway."
"The Green New Deal is modeled after FDRʼs New Deal, which is always celebrated as progressive action that lifted the US out of economic depression through infrastructure development projects like dams and extractive industries that put people to work. Whatʼs far less acknowledged, however, is how much environmental and cultural death and destruction all that development wreaked on Indian country. We see a similar pattern occurring globally in the realm of “sustainable” development, which has given rise to a modern global land rush that impacts Indigenous communities the most. Ultimately, unchecked capitalism is the problem and we need to heed the research that connects cultural diversity with biodiversity if we are to avoid the worst impacts of climate change."
"It is too late for sustainable development."
""Crush not yonder [ant] as it draggeth along its grain; for it too liveth, and its life is sweet to it." A shadow must there be, and a stone upon that heart, that could wish to sorrow the heart even of an [ant]! Strike not with the hand of violence the head of the feeble; for one day, like the ant, thou mayest fall under the foot thyself! Pity the poor moth in the flame of the taper; see how it is scorched in the face of the assembly!"
"Hurt no living thing: Ladybird nor butterfly, Nor moth with dusty wing, Nor cricket cheering cheerily, Nor grasshopper so light of leap, Nor dancing gnat, nor beetle fat, Nor harmless worms that creep."
"The fundamental commandment of ethics, then, is that we cause no suffering to any living creature, not even the lowest, unless it is to effect some necessary protection for ourselves, and that we be ready to undertake, whenever we can, positive action for the benefit of other creatures."
"Ultimately, we don't know for sure that invertebrates suffer in a comparative way to other animals, but given that at any moment the earth contains a billion billion insects, it seems prudent to take the precautionary principle. The potential for these insects to consciously experience some kind of suffering must have an impact on how we interact with them, and our crop fields are a very good place to start."
"This could potentially reduce consumption of vertebrate meat, moving farming away from intensive agriculture towards higher welfare organic systems. Yet entomophagy can only make a significant difference if insects are mass-produced [...] What if these trillions of insects also suffer? If we neglect this possibility, it is feasible that we will move from one intensive poor-welfare system to another, where conscious organisms are inhumanely farmed in greater numbers than anything we have seen before."
"In conclusion, recent results from neurophysiological, neuroanatomical and behavioral sciences prompt caution when denying consciousness, and therefore the likelihood of presence of pain and suffering or something closely related to it, to insects. This strongly underlines earlier statements that while awaiting results of further research one should consider the possibility that at least some insect species might suffer pain and, as a precaution, always ensure humane handling of these animals, including the application of anesthesia and analgesia for painful procedures and humane killing techniques."
"If I save an insect from a puddle, life has devoted itself to life, and the division of life against itself is ended."
"Jumping spiders (Portia spp.) plan routes towards their prey; and hermit crabs (Pagurus berhnardus) show evidence of motivational trade-offs during shell choice. Furthermore, if their brains are implanted with electrodes, garden snails (Helix aspersa) will learn to displace a lever, an action new to their behavioural repertoire, to stimulate those neural regions involved in sexual behaviour. None of these represent concrete evidence of conscious emotion, but they at least suggest that if cephalopods are to now be protected across Europe, then arachnids, decapod crustaceans and gastropods should be too."
"Considerable empirical evidence supports the assertion that insects feel pain and are conscious of their sensations. In so far as their pain matters to them, they have an interest in not being pained and their lives are worsened by pain. Furthermore, as conscious beings, insects have future (even if immediate) plans with regard to their own lives, and the death of insects frustrates these plans. In that sentience appears to be an ethically sound, scientifically viable basis for granting moral status and in consideration of previous arguments which establish a reasonable expectation of consciousness and pain in insects, I propose the following, minimum ethic: We ought to refrain from actions which may be reasonably expected to kill or cause nontrivial pain in insects when avoiding these actions has no, or only trivial, costs to our own welfare."
"The ant is the most pugnacious of all animals, and the most muscular compared with its size. It will boldly attack the biggest creature that walks if this creature invades its home. It will fasten its mandibles into an enemy, and allow itself to be torn to pieces without relaxing its hold. Among some savage tribes, certain species of ants are said to be used as surgeons. Infuriated ants are allowed to fasten their mandibles on the opposite edges of a gash, and in this way the wound is closed. The ants are decapitated, and their bodiless heads with their relentless jaws serve as stitches to the wound."
"[B]ees and other members of the vast class of insects are all capable of sophisticated, learnt, non-stereotyped behaviours that we associate with consciousness if carried out by people."
"We have literally no idea at what level of brain complexity consciousness stops. Most people say, "For heaven's sake, a bug isn't conscious." But how do we know? We're not sure anymore. I don't kill bugs needlessly anymore. [...] Probably what consciousness requires is a sufficiently complicated system with massive feedback. Insects have that."
"So, given that we can't be sure whether insects experience pain, how should we treat these creatures? When I was teaching insect anatomy and physiology I insisted that the students anesthetized insects before conducting experiments that we would expect to inflict pain on a mouse. [...] It seems ethically obligatory to guard against the possibility that insects feel pain. If we use anesthetic and it turns out that insects don't experience pain, the material cost of our mistake is very low [...] However, if we don't use anesthetic and it turns out that the insects were in agony, then the moral cost of our mistake is quite high."
"Great fleas have little fleas upon their backs to bite 'em, And little fleas have lesser fleas, and so ad infinitum. And the great fleas themselves, in turn, have greater fleas to go on; While these again have greater still, and greater still, and so on."
