Past civilizations are buried in the graveyards of their own mistakes, but as each died of its greed, its carelessness or its effeteness another took its place. That was because such civilizations took their character from a locality or region. Today ours is a global civilization; it is not bounded by the Tigris and the Euphrates nor even the Hellespont and the Indus; it is the whole world. Its planet has shrunk to a neighborhood round which a man-made satellite can patrol sixteen times a day, riding the gravitational fences of Man's family estate. It is a community so interdependent that our mistakes are exaggerated on a world scale.

For the first time in history, Man has the power of veto over the evolution of his own species through a nuclear holocaust The overkill is enough to wipe out every man, woman and child on earth, together with our fellow lodgers, the animals, the birds and the insects, and to reduce our planet to a radioactive wilderness. Or the Doomsday Machine could be replaced by the Doomsday Bug. By gene-manipulation and man-made mutations, it is possible to produce, or generate, a disease against which there would be no natural immunity; by "generate" is meant that even if the perpetrators inoculated themselves protectively, the disease in spreading round the world could assume a virulence of its own and involve them too. When a British bacteriologist died of the bug he had invented, a distinguished scientist said, "Thank God he didn't sneeze; he could have started a pandemic against which there would have been no immunity."

Modern Man can outboast the Ancients, who in the arrogance of their material achievements built pyramids as the gravestones of their civilizations. We can blast our pyramids into space to orbit through all eternity round a planet which perished by our neglect.

A hundred years ago Claude Bernard, the famous French physiologist, enjoined his colleagues, "True science teaches us to doubt and in ignorance to refrain," What he meant was that the scientist must proceed from one tested foothold to the next (like going into a mine-field with a mine- detector). Today we are using the biosphere, the living space, as an experimental laboratory. When the mad scientist of fiction blows himself and his laboratory skyhigh, that is all right, but when scientists and decision-makers act out of ignorance and pretend that it is knowledge, they are putting the whole world in hazard. Anyway, science at best is not wisdom; it is knowledge, while wisdom is knowledge tempered with judgment. Because of overspecialization, most scientists are disabled from exercising judgments beyond their own sphere.

A classic example was the atomic bomb. It was the Physicists' Bomb. When the device exploded at Alamogordo on July 16, 1945, and made a notch-mark in history from which Man's future would be dated, the safe-breakers had cracked the lock of the nucleus before the locksmiths knew how it worked. (The evidence of this is the billions of dollars which have been spent since 1945 on gargantuan machines to study the fundamental particles, the components of the nucleus; and they still do not know how they interrelate.)

Prime Minister Clement Attlee, who concurred with President Truman's decision to drop the bomb on Hiroshima, later said: "We knew nothing whatever at that time about the genetic effects of an atomic explosion. I knew nothing about fall-out and all the rest of what emerged after Hiroshima. As far as I know, President Truman and Winston Churchill knew nothing of those things either, nor did Sir John Anderson who coördinated research on our side. Whether the scientists directly concerned knew or guessed, I do not know. But if they did, then so far as I am aware, they said nothing of it to those who had to make the decision."[i]

That sounds absurd, since as long before as 1927, H. J. Muller had been awarded the Nobel Prize for his evidence of the genetic effects of radiation. But it is true that in the whole documentation of the British effort, before it merged in the Manhattan Project, there is only one reference to genetic effects-a Medical Research Council minute which was not connected with the bomb they were intending to make; it concerned the possibility that the Germans might, short of the bomb, produce radioactive isotopes as a form of biological warfare. In the Franck Report, the most statesmanlike document ever produced by scientists, with its percipience of the military and political consequences of unilateral use of the bomb (presented to Secretary of State Henry L. Stimson even before the test bomb exploded), no reference is made to the biological effects, although one would have supposed that to have been a very powerful argument. The explanation, of course, was that it was the Physicists' Bomb and military security restricted information and discussion to the bomb-makers, which excluded the biologists.

The same kind of breakdown in interdisciplinary consultation was manifest in the subsequent testing of fission and fusion bombs. Categorical assurances were given that the fallout would be confined to the testing area, but the Japanese fishing-boat Lucky Dragon was "dusted" well outside the predicted range. Then we got the story of radiostrontium, Radiostrontium is an analogue of calcium. Therefore in bone-formation an atom of natural strontium can take the place of calcium and the radioactive version can do likewise. Radiostrontium did not exist in the world before 1945; it is a man-made element. Today every young person, anywhere in the world, whose bones were forming during the massive bomb-testing in the atmosphere, carries this brandmark of the Atomic Age. The radiostrontium in their bones is medically insignificant, but, if the test ban (belated recognition) had not prevented the escalation of atmospheric testing, it might have been.

Every young person everywhere was affected, and why? Because those responsible for H-bomb testing miscalculated. They assumed that the upthrust of the H-bomb would punch a hole in the stratosphere and that the gaseous radioactivity would dissipate itself. One of those gases was radioactive krypton, which quickly decays into radiostrontium, which is a particulate. The technicians had been wrongly briefed about the nature of the troposphere, the climatic ceiling which would, they maintained, prevent the fall-back. But between the equatorial troposphere and the polar troposphere there is a gap, and the radiostrontium came back through this fanlight into the climatic jet-streams. It was swept all round the world to come to earth as radioactive rain, to be deposited on foodcrops and pastures, to be ingested by animals and to get into milk and into babies and children and adolescents whose growing bones were hungry for calcium or its equivalent strontium, in this case radioactive. Incidentally, radiostrontium was known to the biologists before it "hit the headlines." They had found it in the skin burns of animals exposed on the Nevada testing ranges and they knew its sinister nature as a "bone-seeker." But the authorities clapped security on their work, classified it as "Operation Sunshine" and cynically called the units of radiostrontium "Sunshine Units"- an instance not of ignorance but of deliberate non-communication.

One beneficial effect of the alarm caused by all this has been that the atoms industry is, bar none, the safest in the world for those working in it. Precautions, now universal, were built into the code of practice from the beginning. Indeed it can be admitted that the safety margins in health and in working conditions are perhaps excessive in the light of experience, but no one would dare to modify them. There can, however, be accidents in which the public assumes the risk. At Windscale, the British atomic center in Cumberland, a reactor burned out. Radioactive fumes escaped from the stacks in spite of the filters. They drifted over the country. Milk was dumped into the sea because radioactive iodine had covered the dairy pastures.

There is the problem of atomic waste disposal, which persists in the peaceful uses as well as in the making of nuclear explosives. Low energy wastes, carefully monitored, can be safely disposed of. Trash, irradiated metals and laboratory waste can be embedded in concrete and dumped in the ocean deeps-although this practice raises some misgivings. But high-level wastes, some with elements the radioactivity of which can persist for hundreds of thousands of years, present prodigious difficulties. There must be "burial grounds" (or euphemistically "farms"), the biggest of which is at Hanford, Washington. It encloses a stretch of the Columbia River in a tract covering 650 square miles, where no one is allowed to live or to trespass.

There, in the twentieth century Giza, it has cost more, much more, to bury live atoms than it cost to entomb the sun-god Kings of Egypt. The capital outlay runs into hundreds of millions of dollars and the maintenance of the U.S. sepulchres is over $6 million a year. (Add to that the buried waste of the U.S.S.R., Britain, Canada, France and China, and one can see what it costs to bury live atoms.) And they are very much alive. At Hanford they are kept in million-gallon carbon-steel tanks. Their radioactive vitality keeps the accompanying acids boiling like a witches' cauldron. A cooling system has to be maintained continuously. The vapors from the self-boiling tanks have to be condensed and "scrubbed" (radioactive atoms removed); otherwise a radioactive miasma would escape from the vents. The tanks will not endure as long as the pyramids and certainly not for the hundreds of thousands of years of the long-lived atoms. The acids and the atomic ferments erode the toughest metal, so the tanks have to be periodically decanted. Another method is to entomb them in disused salt mines. Another is to embed them in ceramics, lock them up in glass beads. Another is what is known as "hydraulic fraction": a hole is drilled into a shale formation (below the subsoil water); liquid is piped down under pressure and causes the shale to split laterally. Hence the atoms in liquid cement can be injected under enormous pressure and spread into the fissures to set like a radioactive sandwich. This overcomes the worry of earthquakes since the materials will remain secure even in faulting.

This accumulating waste from fission plants will persist until the promise, still far from fulfilled, of peaceful thermonuclear power comes about With the multiplication of power reactors, the wastes will increase. It is calculated that by the year 2000, the number of six-ton nuclear "hearses" in transit to "burial grounds" at any given time on the highways of the United States will be well over 3,000 and the amount of radioactive products will be about a billion curies, which is a mighty lot of curies to be roaming around a populated country.

The alarming possibilities were well illustrated by the incident at Palomares, on the coast of Spain, when there occurred a collision of a refueling aircraft with a U.S. nuclear bomber on "live" mission. The bombs were scattered. There was no explosion, but radioactive materials broke loose and the contaminated beaches and farm soil had to be scooped up and taken to the United States for burial.

Imagine what would have happened if the Torrey Canyon, the giant tanker which was wrecked off the Scilly Isles, had been nuclear-powered. Some experts make comforting noises and say that the reactors would have "closed down," but the Torrey Canyon was a wreck and the Palomares incident showed what happens when radioactive materials break loose. All those oil-polluted beaches of southwest England and the coasts of Brittany would have had to be scooped up for nuclear burial.


The Torrey Canyon is a nightmarish example of progress for its own sake. The bigger the tanker the cheaper the freightage, which is supposed to be progress. This ship was built at Newport, Virginia, in 1959 for the Union Oil Corporation; it was a giant for the time-810 feet long and 104 feet beam-but, five years later, that was not big enough. She was taken to Japan to be "stretched." The ship was cut in half amidship and a mid-body section inserted. With a new bow, this made her 954 feet long, and her beam was extended 21 feet She could carry 850,000 barrels of oil, twice her original capacity.

Built for Union Oil, she was "owned" by the Barracuda Tanker Corporation, the head office of which is a filing cabinet in Hamilton, Bermuda. She was registered under the Liberian flag of convenience and her captain and crew were Italians, recruited in Genoa. Just to complicate the international tangle, she was under charter to the British Petroleum Tanker Company to bring 118,000 tons of crude oil from Kuwait to Milford Haven in Wales, via the Cape of Good Hope. Approaching Lands End, the Italian captain was informed that if he did not reach Milford Haven by 11 p.m. Saturday night, he would miss highwater and would not be able to enter the harbor for another five days, which would have annoyed his employers. He took a shortcut, setting course between Seven Stones rocks and the Scilly Isles, and he finished up on Pollard Rock, in an area where no ship of that size should ever have been.

Her ruptured tanks began to vomit oil and great slicks spread over the sea in the direction of the Cornish holiday beaches. A Dutch tug made a dash for the stranded ship, gambling on the salvage money. (Where the salvaged ship could have been taken one cannot imagine, since no place would offer harborage to a leaking tanker). After delays and a death in the futile salvage effort, the British Government moved in with the navy, the air force and, on the beaches, the army. They tried to set fire to the floating oil which, of course, would not volatilize. They covered the slicks with detergents (supplied at a price by the oil companies), and then the bombers moved in to try to cut open the deck and, with incendiaries, to set fire to the remaining oil in the tanks. Finally the ship foundered and divers confirmed that the oil had been effectively consumed.

Nevertheless the result was havoc. All measures had had to be improvised. Twelve thousand tons of detergent went into the sea. Later marine biologists found that the cure had been worse than the complaint The oil was disastrous for seabirds, but marine organic life was destroyed by the detergents. By arduous physical efforts, with bulldozers and flame-throwers and, again, more detergents, the beaches were cleaned up for the holiday- makers. Northerly winds swept the oil slicks down Channel to the French coast with even more serious consequences, particularly to the valuable shellfish industry. With even bigger tankers being launched, this affair is a portentous warning.

Two years after Torrey Canyon an offshore oil rig erupted in the Santa Barbara Channel. The disaster to wildlife in this area, which has island nature reserves and is on the migratory route of whales, seals and seabirds, was a repetition of the Torrey Canyon oil-spill. And the owner of the lethal oil rig was Union Oil


Another piece of stupidity shows how much we are at the mercy of ignorant men pretending to be knowledgeable. During the International Geophysical Year, 1957-58, the Van Alien Belt was discovered. This is an area of magnetic phenomena. Immediately it was decided to explode a hydrogen bomb in the Belt to see whether an artificial aurora could be produced. The colorful draperies and luminous skirts of the aurora borealis are caused by the drawing in of cosmic particles through the rare gases of the upper atmosphere-ionization it is called; it is like passing electrons through the vacuum tubes of our familiar florescent lighting. The name Rainbow Bomb was given it in anticipation of the display it was expected to produce. Every eminent scientist in the field of cosmology, radio-astronomy or physics of the atmosphere protested at this irresponsible tampering with a system which we did not understand. And typical of the casual attitude toward this kind of thing, the Prime Minister of the day, answering protests in the House of Commons that called on him to intervene with the Americans, asked what all the fuss was about. After all, they hadn't known that the Van Allen Belt even existed a year before. This was the cosmic equivalent of Chamberlain's remark about Czechoslovakia, at the time of Munich, about that distant country of which we knew so little. They exploded the bomb. They got their pyrotechnics and we still do not know the cost we may have to pay for this artificial magnetic disturbance.

In the same way we can look with misgivings on those tracks-the white tails of the jets, which are introducing into our climatic system new factors, the effects of which are immensurable. Formation of rain clouds depends upon water vapor having a nucleus on which to form. That is how artificial precipitation is introduced-the so-called rain-making. So the jets, criss- crossing the weather system, playing noughts and crosses with it, can produce a man-made change.

In the longer term we can foresee even more drastic effects from Man's unthinking operations. At the United Nations' Science and Technology Conference in Geneva in 1963 we took stock of the effects of industrialization on our total environment thus far. The atmosphere is not only the air which humans, animals and plants breathe; it is also the envelope which protects living things from harmful radiation from the sun and outer space. It is also the medium of climate, the winds and the rain. Those are inseparable from the hydrosphere-the oceans, covering seven- tenths of the globe, with their currents and extraordinary rates of evaporation; the biosphere, with its trees and their transpiration; and, in terms of human activities, the minerals mined from the lithosphere, the rock crust. Millions of years ago the sun encouraged the growth of the primeval forests, which became our coal, and the plant growth of the seas, which became our oil. Those fossil fuels, locked away for æons of time, are extracted by man and put back into the atmosphere from the chimney stacks and the exhaust pipes of modern engineering. About 6 billion tons of carbon are mixed with the atmosphere annually. During the past century, in the process of industrialization, with its release of carbon by the burning of fossil fuels, more than 400 billion tons of carbon have been artificially introduced into the atmosphere. The concentration in the air we breathe has been increased by approximately 10 percent, and if all the known reserves of coal and oil were burnt, the concentration would be ten times greater.

This is something more than a public health problem, more than a question of what goes into the lungs of an individual, more than a question of smog. The carbon cycle in nature is a self-adjusting mechanism. Carbon dioxide is, of course, indispensable for plants and is, therefore, a source of life, but there is a balance which is maintained by excess carbon being absorbed by the seas. The excess is now taxing this absorption and it can seriously disturb the heat balance of the earth because of what is known as the "greenhouse effect." A greenhouse lets in the sun's rays but retains the heat. Carbon dioxide, as a transparent diffusion, does likewise. It keeps the heat at the surface of the earth and in excess modifies the climate.

It has been estimated that, at the present rate of increase (6 billion tons a year), the mean annual temperature all over the world might increase by 3.6 degrees centigrade in the next forty to fifty years. The experts may argue about the time factor and even about the effects, but certain things are apparent, not only in the industrialized northern hemisphere but in the southern hemisphere also. The north-polar ice-cap is thinning and shrinking. The seas, with their blanket of carbon dioxide, are changing their temperature, with the result that marine plant life is increasing and is transpiring more carbon dioxide. As a result of the combination, fish are migrating, changing even their latitudes. On land the snow line is retreating and glaciers are melting. In Scandinavia, land which was perennially under snow and ice is thawing, and arrowheads of over 1,000 years ago, when the black soils were last exposed, have been found. The melting of sea ice will not affect the sea level, because the volume of floating ice is the same as the water it displaces, but the melting of ice caps or glaciers, in which the water is locked up, will introduce additional water to the sea and raise the level. Rivers originating in glaciers and permanent snow fields will increase their flow; and if ice dams, such as those in the Himalayas, break, the results in flooding may be catastrophic. In this process the patterns of rainfall will change, with increased precipitation in some areas and the possibility of aridity in now fertile regions. One would be well-advised not to take ninety-nine year leases on properties at present sea level.


At that same conference, there was a sobering reminder of mistakes which can be writ large, from the very best intentions. In the Indus Valley in West Pakistan, the population is increasing at the rate of ten more mouths to be fed every five minutes. In that same five minutes in that same place, an acre of land is being lost through water-logging and salinity. This is the largest irrigated region in the world. Twenty-three million acres are artificially watered by canals. The Indus and its tributaries, the Jhelum, the Chenab, the Ravi, the Beas and the Sutlej, created the alluvial plains of the Punjab and the Sind. In the nineteenth century, the British began a big program of farm development in lands which were fertile but had low rainfall. Barrages and distribution canals were constructed. One thing which, for economy's sake, was not done was to line the canals. In the early days, this genuinely did not matter. The water was being spread from the Indus into a thirsty plain and if it soaked in so much the better. The system also depended on what is called "inland delta drainage," that is to say, the water spreads out like a delta and then drains itself back into the river. After independence, Pakistan, with external aid, started vigorously to extend the Indus irrigation. The experts all said the soil was good and would produce abundantly once it got the distributed water. There were plenty of experts, but they all overlooked one thing-the hydro- logical imperatives. The incline from Lahore to the Ram of Kutch-700 miles- is a foot a mile, a quite inadequate drainage gradient. So as more and more barrages and more and more lateral canals were built, the water was not draining back into the Indus. Some 40 percent of the water in the unlined canals seeped underground, and in a network of 40,000 miles of canals that is a lot of water. The result was that the watertable rose. Low-lying areas became waterlogged, drowning the roots of the crops. In other areas the water crept upwards, leaching salts which accumulated in the surface layers, poisoning the crops. At the same time the irrigation régime, which used just 1½ inches of water a year in the fields, did not sluice out those salts but added, through evaporation, its own salts. The result was tragically spectacular. In flying over large tracts of this area one would imagine that it was an Arctic landscape because the white crust of salt glistens like snow.

The situation was deteriorating so rapidly that President Ayub appealed in person to President Kennedy, who sent out a high-powered mission which encompassed twenty disciplines. This was backed by the computers at Harvard. The answers were pretty grim. It would take twenty years and $2 billion to repair the damage-more than it cost to create the installations that did the damage. It would mean using vertical drainage to bring up the water and use it for irrigation, and also to sluice out the salt in the surface soil. If those twenty scientific disciplines had been brought together in the first instance it would not have happened.

One more instance of the far-flung consequences of men's localized mistakes: No insecticides or pesticides have ever been allowed into the continent of Antarctica. Yet they have been found in the fauna along the northern coasts. They have come almost certainly from the Northern Hemisphere, carried from the rivers of the farm-states into the currents sweeping south. In November 1969, the U.S. Government decided to "phase out" the use of DDT.

Pollution is a crime compounded of ignorance and avarice. The great achievements of Homo sapiens become the disaster-ridden blunders of Unthinking Man-poisoned rivers and dead lakes, polluted with the effluents of industries which give something called "prosperity" at the expense of posterity. Rivers are treated like sewers and lakes like cesspools. These natural systems-and they are living systems-have struggled hard. The benevolent micro-organisms which cope with reasonable amounts of organic matter have been destroyed by mineral detergents. Witness our foaming streams. Lake Erie did its best to provide the oxygen to neutralize the pickling acids of the great steel works. But it could not contend. It lost its oxygen in the battle. Its once rich commercial fishing industry died and its revitalizing microorganic life gave place to anaerobic organisms which do not need oxygen but give off foul smells, the mortuary smells of dead water. As one Erie industrialist retorted, "It's not our effluent; it's those damned dead fish."

We have had the Freedom from Hunger Campaign; presently we shall need a Freedom from Thirst Campaign. If the International Hydrological Decade does not bring us to our senses we will face a desperate situation. Of course it is bound up with the increasing population but also with the extravagances of the technologies which claim that they are serving that population. There is a competition between the water needs of the land which has to feed the increasing population and the domestic and industrial needs of that population. The theoretical minimum to sustain living standards is about 300 gallons a day per person. This is the approximate amount of water needed to produce grain for 2½ pounds of bread, but a diet of 2 pounds of bread and 1 pound of beef would require about 2,500 gallons. And that is nothing compared with the gluttonous requirements of steel-making, paper- making and the chemical industry.

Water-just H2O-is as indispensable as food. To die of hunger one needs more than fifteen days. To die of thirst one needs only three. Yet we are squandering, polluting and destroying water. In Los Angeles and neighboring Southern California, a thousand times more water is being consumed than is being precipitated in the locality. They have preëmpted the water of neighboring states. They are piping it from Northern California and there is a plan to pipe it all the way from Canada's North-West Territories, from the Mackenzie and the Liard which flow northwards to the Arctic Ocean, to turn them back into deserts.


Always and everywhere we come back to the problem of population-more people to make more mistakes, more people to be the victims of the mistakes of others, more people to suffer Hell upon Earth. It is appalling to hear people complacently talking about the population explosion as though it belonged to the future, or world hunger as though it were threatening, when hundreds of millions can testify that it is already here-swear it with panting breath.

We know to the exact countdown second when the nuclear explosion took place- 5:30 a.m., July 16, 1945, when the first device went off in the desert of Alamogordo, New Mexico. The fuse of the population explosion had been lit ten years earlier-February 1935. On that day a girl called Hildegarde was dying of generalized septicaemia. She had pricked her finger with a sewing needle and the infection had run amok. The doctors could not save her. Her desperate father injected a red dye into her body. Her father was Gerhard Domagk. The red dye was prontosil which he, a pharmaceutical chemist, had produced and had successfully used on mice lethally infected with streptococci, but never before on a human. Prontosil was the first of the sulfa drugs-chemotherapeutics, which could attack the germ with the living body. Thus was prepared the way for the rediscovery of penicillin- rediscovery because although Fleming had discovered it in 1928, it had been ignored because neither he nor anybody else had seen its supreme virtue of attacking germs with the living body. That is the operative phrase, for while medical science and the medical profession had used antiseptics for surface wounds and sores, they were always labeled "Poison, not to be taken internally." The sulfa drugs had shown that it was possible to attack specific germs within the living body and had changed this attitude. So when Chain and Florey looked again at Fleming's penicillin in 1938, they were seeing it in the light of the experience of the sulphas.

A new era of disease-fighting had begun-the sulfas, the antibiotics, DDT insecticides. Doctors could now attack a whole range of invisible enemies. They could master the old killer diseases. They proved it during the war, and when the war ended there were not only stockpiles of the drugs, there were tooled up factories to produce them. So to prevent the spread of the deadly epidemics which follow wars, the supplies were made available to the war-ravaged countries with their displaced persons, and then to the developing countries. Their indigenous infections and contagions and insect- borne diseases were checked.

Almost symbolically, the first great clinical use of prontosil had been in dealing with puerperal sepsis, childbed fever. It had spectacularly saved mothers' lives in Queen Charlotte's Hospital, London, Now its successors took up the story. Fewer mothers died in childbirth, to live and have more babies. Fewer infants died, fewer toddlers, fewer adolescents. They lived to marry and have children. Older people were not killed off by, for instance, malaria. The average life-span increased.

Professor Kingsley Davis of the University of California at Berkeley, the authority on urban development, has presented a hair-raising picture from his survey of the world's cities. He has shown that 38 percent of the world's population is already living in what are defined as urban places. Over one-fifth of the world's population is living in cities of 100,000 or more. And over one-tenth of the world's population is now living in cities of a million or more inhabitants. In 1968, 375 million people were living in million-and-over cities. The proportions are changing so quickly that on present trends it would take only 16 years for half the world's population to be living in cities and only fifty-five years for it to reach 100 percent

Within the lifetime of a child born today, Kingsley Davis foresees, on present trends of population-increase, 15 billion people to be fed and housed-nearly five times as many as now. The whole human species would be living in cities of a million-and-over inhabitants, and-wait for it!-the biggest city would have 1.3 billion inhabitants. That means 186 times as many as there are in Greater London.

For years the Greek architect Doxiadis has been warning us about such prospects. In his Ecumenopolis-World City-one urban area like confluent ulcers would ooze into the next. The East Side of World City would have as its High Street the Eurasian Highway stretching from Glasgow to Bangkok, with the Channel Tunnel as its subway and a built-up area all the way. On the West Side of World City, divided not by the tracks but by the Atlantic, the pattern is already emerging, or rather, merging. Americans already talk about Boswash, the urban development of a built-up area stretching from Boston to Washington; and on the West Coast, apart from Los Angeles, sprawling into the desert, the realtors are already slurring one city into another all along the Pacific Coast from the Mexican Border to San Francisco. We don't need a crystal ball to foresee what Davis and Doxiadis are predicting; we can already see it through smog-covered spectacles; a blind man can smell what is coming.

The danger of prediction is that experts and men of affairs are likely to plan for the predicted trends and confirm these trends. "Prognosis" is something different from "prediction." An intelligent doctor having diagnosed your symptoms and examined your condition does not say (except in novelettes), "You have six months to live." An intelligent doctor says, "Frankly, your condition is serious. Unless you do so-and-so, and I do so- and-so, it is bound to deteriorate." The operative phrase is "do so-and- so." We don't have to plan for trends; if they are socially undesirable our duty is to plan away from them; to treat the symptoms before they become malignant.

We have to do this on the local, the national and the international scale, through intergovernmental action, because there are no frontiers in present- day pollution and destruction of the biosphere. Mankind shares a common habitat. We have mortgaged the old homestead and nature is liable to foreclose.
