Human attack on the earth By ALAN KETTLER IN JUST the next 25 years, the Earth is expected to sustain two to three billion more people, each vying with the other and the four billion now living for food, fuel, clothing, shelter, and any other goods and services society offers them. The most basic of these wants is food. Unfortunate- ly, Man's attempts to wrest foodstuffs out of the earth have had and will continue to have disastrous effects on the Earth's ecosystems. What differentiates past from present is the unprecedented scale in which the Earth is being assaulted. Increased agricultural pro- duction in the next decade will change the land- scape, productivity, and ecological significance of lands more than any comparable amount of time in history. Man's use of resources in two different environments illustrate the process of land ruination and its long- term, far-ranging effects. First of all, biotic existence and soil productivity are being torn asunder by subsistence agriculturalists in the Sahel region of Africa. Traversing the width of Africa at the 3,500 mile long southern flank of the Sahara Desert, it is a transition zone between the desert and savannas to the south. HERE, THE fragile ecosystem has yielded to over- exploitation by the grazing of cattle and goats. Domes- tic animals eat more food than the arid region can produce, with the result that the land is denuded. Man's overgrazing and forest removal have created The tropical rain forests contain the most incred- ibly diverse set of organisms found on Earth. Here, one finds big cats, sloths, anteaters, dazzling birds, monkeys, and giant nakes. One eleven acre section of Amozian rain forest studied by a WWF scientist held at least 295 species of trees. We are accustomed to forests with about a dozen kinds of trees. UNFORTUNATELY, the species richness unique to these forests is deceptive. Each species is represented by relatively few individuals, which are widely scat- tered. Most misleading is the lush vegetation of the tropics. The abundant greenery, rainfall, and sunshine would indicate that the land is a potential paradise. But the land is not as fertile as it appears to be. While most of the nutrients in temperate forests such as ours are found in the soil, 70 per cent of the nu- trients in a tropical forest are found in its plants. When organic matter falls to the gropnd, it is quickly de- composed and taken up by the extensive root systems of the living forest. Thus the nurient layer on the forest floor is very thin. Therein lies the danger of farming tropical lands, as will now be illustrated. The most prevalent type of tropical farming is the slash-and-burn method. An area is felled, the litter is burnt, and crops are planted. Because of the greatly reduced plant cover, nutrients are leached through the soil by the frequent rains. 'We operate on the general premise that you're guilty until proven innocent.' "The War in Indochina was as much a war on land as on peoples. Twenty- one million bomb craters there cover about 345,000 acres. U.S. bulldozers scraped away 800,000 acres of vegetation, and herbicides deforested one- sixth of Vietnam's forests." .:......... s . ..... f.. ... ...'....... ..... .. . Eighty-four years of editorial freedom Edited and managed by students at the University of Michigan Friday, March 14, 1975 News Phone: 764-0552 420 Maynard St., Ann Arbor, Mi. 48104 Legalize gambling in state SENATE BILL 92, introduced earlier this year by State Senator Daniel Cooper, is designed to relax Michi- gan's ban on gambling. The bill pro- vides for state licensing of a limited number of modified casino opera- tions in the state. Though managed by private operators, the establish- ments would be closely regulated and their practices regularly reviewed by the state. Cooper's bill alone could by no means spell the end of illegal gamb- ling across the state. But it might do much to both undercut mafia-con- trolled gambling rings and give a much-needed shot in the arm to the state treasury. A number of the more virtuous in- habitants of the Winter Water Won- derland deplore and dismiss a state takeover of the gambling rackets as a corruption of governmental values. Their intentions are noble, but their grasp on the underside of life in Michigan leaves much to be desired. LARGE-SCALE GAMBLING is a cold but unescapable fact of life in the state and across the nation. State law enforcement agencies have poured untold millions of dollars into their crusade against the mob- controlled gaming rackets. For the most parts, their efforts have been fruitless. Occasionally, a local vice squad will collar a low-level racke- teer or latch onto a high school- bound shipment of football parlay cards. But still the mafioso machine keep chugging along, making a crippling dent in millions of Michi- gan paychecks and shaving the odds to keep their lackeys in the hole. Gambling is as much an addiction as alcoholism or a heroin habit, and the condition of odds-junkies - and there are millions of them in fac- tories, schools, taverns and offices across the state will only worsen as long as the underworld element rules. THOSE WHO'VE LEARNED the les- sons of countless fruitless efforts to drive out the gambling hordes rea- lize that if you can't end the game, you may as well make the rules. The state may not be able to make book with the charm and flair of a local neighborhood bookies, but also won't use the unrefusable offer ap- proach to collecting bad debts and keeping recalcitrants in line. In the media and literature, pe- destrian gambling is too often por- trayed as a mischievous and mostly harmless side attraction to life. The cold reality of a daily fix in the num- bers racket is one of life's darker tragedies. The billions of dollars peo- ple unwittingly forfeit to the mob every year not only damages their own lifestyles. it also directly contri- butes to the financing of more dead- lv mafia games like the narcotics trade. IT'S TIME TO recognize an en- trenched though regrettable in- stitution for what it is, and promote steps - like Senator Cooper's bill- to bring the gambling industry under control, if not respect. a large part of the Sahara Desert. Once the vegetation on its periphery is removed, the soil is openly expos- ed to the eroding forces of wind and rain. Loss of vege- tation greatly reduces the absorptive capacities of the soil, so when rain does come, most quickly runs off the surface of the ground. Dry gullies and stream beds can become roaring torrents, washing away precious top soil and cutting gullies into the landscape. Evaporation is quicker be- cause of plant cover loss, too. Into the sky blows the bare, dry topsoil left behind. Meanwhile, the great water runoff increases flooding and destruction down- stream. What remains is a useless land which can only be restored through extensive, expensive means, if at all. Thus, the desert expands. A U.S. government study states that the desert is moving southward up to 30 miles a year in some places. Once an area i deplet- ed, its inhabitants move southward, where condi- tions are repeated and the desert advances again. The only thing growing well in the African Sahel is the Sahara Desert. ELSEWHERE IN Africa, the clearing and use of land is having heavy consequences. Flourishing environ- ments once operated in an ecologically balanced way with continued highproductivity. Now, once wet rivers are dry, soils are eroded to bare rock, vegetation and wild animals have disappeared, water tables sink, cli- mates deteriorate, surrounding areas are injured, and desertification continues. Increasing populations of hu- mans and livestock are destroying the productivity of the land and building themselves up to a collapse. Meanwhile, agricultural production in the world's tropics proceeds quickly and dangerously. The inter- nationally based World Wildlife Fund does not stand alone when it states that in the next 25 years we will probably witness the nearly complete destruction of the Earth's rain forests, AFTER TWO or three years of favorable harvests, most of the nutrients will have been washed out. The area is abandoned, and a new clearing is made. What happens to the abandoned land is an irrever- sibly destructive proces called laterization. Without forest cover, rains wash out all the soluble elements in the soil. The insoluble matter that remains is baked by the blazing tropical sun to a rock-like consistency. F. R. Fosbery, tropical ecologist and botanist at the Smithsonian Institution, tells of seeing thousands and thousands of acres in northern equatorial Africa where laterization has occurred. "The ground becomes so hard you can hit it with a hammer and the hammer will bounce back at you," he says. "And as far as I know, there is no way of restoring the productivity of such affected soils." As in sub-Sahara Africa, a positive feedback system exacerbates the situation. As land productivity is de- stroyed, less arable land is left remaining for an ever- increasing number of farmers. Every time a productive acre of land is lost, a complementary acre of good land is doomed to be lost (if land-use practices do not improve). As population and ruined acreage increase, an ever-accelerating amount of tillable land will neces- sarily decrease. In practice it is an agricultural sys- tem with virtually no stability or long-term viability. THE POPULATION of rain-forested countries will generally double in the next 25 years. Like Brazil, which alone will add 100 million people in that time, growing countries are using their sparsely inhabited rain forests as overflow basins for people. The effects of the projected complete deforestation and incomplete soil ruination of the tropics will be unlike any thing the world has ever experienced. In the Amazon alone, an estimated million plant and animal species will be exterminated. Assuming the combined forests of Africa, Asia, and Indonesia lost the same number, the natural systems of the world "The Sahara Desert is moving south- ward up to 30 miles a year in some places. Once an area is depleted, its inhabitants move southward, where conditions are repeated and the de- sert advances again." would lose one-fifth of their members. Gone forever would be the incredible showcase of the rain forests' inhabitants. Gone forever would be their evolutionary potential. Gne forever would be valuable scientific information about these species. Most of the organisms will become extinct before they are even discovered and described. It is an undeniable principle of life that every liv- ing thing afects every other living thing. However, what we do not know is how the loss of so many spec- ies will affect surviving species, including our own. EVEN THE physical world is threatened by tropical exploitation. Scientists are about even divided as to whether or not such massive vegetation losses could affect the earth's climate. Forests do regulate the runoff of rainfall, slow evaporation by blocking the sun and trapping humid air, and lessen temperature extremes. Deforested and barren lands will reflect more heat than forests, possibly affecting wind cur- rents and thus rainfall distribution patterns. The enormous problems of devegetation, erosion, and extinction do not stop with agricultural production. The War in Indochina was as much a war on land as on peoples. Twenty-one million bomb craters there cov- er about 345,000 acres. U.S. bulldozers scraped away 800,000 acres of vegetation, and herbicides deforested one-sixth of South Vietnam's forests. In 1973, 500 companies were vying for timber con- cessions in the 60 million acres of remaining virgin low- land rain forests in Indoesia. At that time, the inade- quately trained and developed forest service showed a lack of control over logging operations. ONE NATION in quest of other resources is tearing its land apart. A governmental department eliminates the protective vegetation of streams and rivers. In- dustries scrape away the living envelope of millions of acres of land to get at energy-producing coal. Wood and paper companies cut huge swaths into forests, leaving stump forests and battered, exposed soils. That nation is this one. The world must take off its blinders. Population growth in both developed and developing countries must slow down. A more rational use of resources, par- ticularly in the United States, would help to make possible a sound redistribution of resources. For example, the food Americans feed their pets is enough to feed the undernourished third of the world. Also, development projects in developing countries should offer assistance with stability, self-sufficiency, and ecological sanity as their goals. The ravaging of the planet Earth continues, and is worsening. It is ultimately from the soil that the wealth of any society is based. If population pressures force current land use patterns to persist, we will have added one more gargantuan blow to an increasingly overloaded and bewildered political and natural order. The results could be disastrous. Alan Kettler is an LSA sophomore and frequent contributor to the Editorial Page. Curbside suicide: It's your own fault! Subversion of free speech THE RECENT disruption of Israeli President E p h r a i m Katzir's speech raises serious questions about the nature of free speech at the Uni- versity. The crux of the matter is this. Does the expression of odious beliefs cancel the right to express them? Or does the University guaran- tee by its charter and purpose, the right to express anything no matter how disgusting? The Palestinians and their support- ers on campus believe in the former line, arguing that Katzir, who served in the underground Hagganah, is a Hitler and not entitled to complete his remarks. Such arguments are faulty. While Katzir may or may not be a "Hitler", TODAY'S STAFF: he is protected in his right to speak by the very nature of the University. His beliefs may or may not be odious, his background repugnant, but this in no way cancels his right to be heard. The University may stand for values like progressivism, justice, or- der, and concern for the communityy in varying degrees. Hopefully they will reflect these values, and should be held to account If they fail. BUT SUCH VALUES are not the pri- mary purpose of a University- the expression of thought is. If the University fails to meet its primary obligation of protecting free speech and thought, it fails to meet the pur- pose for which it was constructed. If it abandons that purpose, it should not exist. Ths mi,,i.QP oft iPr nnp n t n+ By WAYNE JOHNSON A FEW summer jobs ago, I met a man who ran over and killed a young child on Van Dyke, a madly busy Detroit street. According to eyewitness- es, the driver was blameless. A seven year old girl simply ran into traffic thinking, per- haps, she would magically ap- pear on the other side. Instead, the police and ambulance at- tendants had to scrape a sub- stantial portion of her body from an automobile right front wheel. I only knew this man a few weeks before he turned into a "killer" but the change in his personality was obvious. Three months later he still barely spoke to his co-workers, prefer- ring to remain within his own thoughts. And such nice thoughts they must have been. Imagine watching the face of a child an instant before you spill her guts on the street. By now thisman has probab- ly worked the incident into an image that he can live with more easily. But he still isn't likely to speak of his horrible experience to casual acquaint- ances. MORE RECENTLY, an Ann Arbor Councilman killed h i s neighbor in the same grisly manner, by slamming into him with a moving car. It has now become quite apparent to me that I will be very lucky if I survive Ann Arbor without of- fing a fellow student in similar style. There are so many candidates for destruction each driving day that I often wonder which one you walk in front of moving cars with the thought, "H 'Il stop," firmly entrenched in your mind? Do you like to wait for traffic to clear about inree steps off the curb? Are you occasionaly seized with the per- verse desire to really hurt your girlfriend, boyfriend, father or mother by getting yourself squished into the cement? NO? THEN why the hell am I constantly wondering how many of your toes I chopped off on S. University? Why don'" you back up and wait on the cirb like a nice, rational pers-on? Afraid the other kids might call you "chicken?" After all, you have no idea what kind of evil ideas e a e h driver might be considering. Personally, I must admit there are a few types of peaple I would actually enjoy giving one of those spectacular five 1-un- dred yard air and concrete boosts you read about in thle papers. If you recognize your- self in these descriptions, be- ware your fellow man. One type is the "Pacer". He steps out from class or hame with this single, unammendable promise to himself, "I will not slop, slow down or speed up for anything." The Pacer believes he is an automobile without brakes and is thus justified in his journey. Most drivers can spot thf- Pac- er immediately. He comes storming toward the street, eyes flashing, daring any ,f those stupid drivers to challenge him. If you hit the Pacer he has al- ready planned what he will do- kick the crap out .f your car writh the. ha, hant hs uers. the several near misses I've al- ready had, I'll bet I could forgive myself for killing a Pac- er within a week. Another self destructive type, called Jack and Sally Ins-me, contnnually plague me. Aroind automobiles, Mr. and Ms. in- sane are prone to foolish activ- ity. For example, if a car is stopped for a sign or a :ght, Jack and Sally will have uncon- trollable urges to throw them- selves under the tires. Most of the time they will ies- iate before they act, alliowirig the alert driver a good chance to escape. With eyes shifting at a tremendous rate. the Insines difficult for anyone else to guess. When struck, Jack and Sally won't whimper or ask for explanations. They realize death is just a normal part of living. But the largest group of death defiers is known as the Dream- ers. These people were not plac- ed on Earth to pay atten'ion to mundane things like moving cars and trucks. Heavens no, the Dreamers are considering the answers to the world's pr- lems and cannot be expec ed to realize where their legs ar: tak- ing them. A quick demise is too h unod for these people. They should pound their chances of death by giving these maniacs extra opportunities to run them down. SINCE MOST of us are part time drivers and pedestrians, it shouldn't be difficult for each to empathize with the other's problems. Why then, do pedes- trians constantly forget how long it takes to bring a rnov- ing auto to a complete halt? So, if you are walking around Ann Arbor believing that you have the same rights as auto- mobiles, I would like to bid you goodbye and good luck. Tech- nically, you are correct, but it will be difficult to argue your
