A new spirit                     is abroad as scientists and laymen realize that man and the                     rest of nature are united and indivisible.<\/p>\n<p> At a time when great elemental forces are clamouring at                     the bars of our civilization we need to discard our ideas                     of &#8220;attacking&#8221; the forest, &#8220;bringing under subjection&#8221; the                     mighty rivers, &#8220;conquering&#8221; the mountains, and &#8220;subduing&#8221;                     the prairie. Instead, we need to make the most of all nature                     as an ally.<\/p>\n<p>Mankind is welcome to dominate the other forms of life,                     provided he can maintain order among the relentless energies                     whose balanced operation he has disturbed. This is a hard                     condition. Our past is full of sombre warnings of what happens                     when we fail to meet it. The evidence is in the remnants of                     great civilizations buried beneath mud and sand.<\/p>\n<p>Only when we recognize that the study of all living things                     is a profoundly necessary part of human thought do we reach                     the&#8221; moment of truth. Then we realize that we are part of                     a complex stretching back to the beginning of time and reaching                     out on every hand to the boundaries of the universe. Every                     one of us is an actor in a great drama in which each plays                     his part as both cause and effect.<\/p>\n<p>The forces set in motion by every act of every animal and                     bacterium, by every inch added to the growth of plant or tree,                     affect the lives of other creatures. The principles which                     govern these interrelationships are embraced in the science                     called ecology, a word coming from the Greek for &#8220;home&#8221; or                     &#8220;estate&#8221;. Ecology is the study of how the household of nature                     is kept in order.<\/p>\n<p>This <em>Monthly Letter <\/em>has to do with renewable resources,                     the essentials of life. Our primitive ancestors made their                     way for millions of years before they discovered how to use                     iron, copper, coal, oil and gold. But never has man been able                     to get along without food and water. This is why the relationship                     of all living things has urgent meaning for us.<\/p>\n<h3>The state of affairs today<\/h3>\n<p>In a subject so old, so vast, and so continually new, it                     seems to be impossible to keep science and social life apart.                     In fact, we should not try to do so. Continuance of our human                     society depends upon our ability to heed the science of the                     rest of nature, and live within its bounds.<\/p>\n<p>There are at least three good reasons for surveying the                     present state of affairs and learning about our natural environment:                     (1) our advancing technology uses up resources in increasing                     quantity; (2) our increasing population puts annually greater                     pressure upon our living space; (3) our continued existence                     depends upon our keeping our natural environment productive                     of the essentials of life.<\/p>\n<p>Over and above the slow changes by natural causes such as                     climate, the earth has suffered measureless destruction of                     animals and plants by the uncalculating actions of both savage                     and civilized men.<\/p>\n<p>It was destruction of their environment that caused salmon                     to disappear from Lake Ontario, and the bison to die off our                     Western plains, and the passenger pigeon to vanish from North                     America. Forests have been burnt up, soil has been washed                     away, deserts have been produced, and rivers have been polluted.                     &#8220;We have,&#8221; said Professor A. F. Coventry to the Toronto Field                     Naturalists&#8217; Club, &#8220;for a long time been breaking the little                     laws, and the big laws are beginning to catch up with us.&#8221;<\/p>\n<h3>The balance of nature<\/h3>\n<p>Nature has its laws designed to maintain balance. If the                     number of any living species tends to increase out of proportion,                     some force will arise to control it. There is an equilibrium                     in undisturbed nature between food and feeder, hunter and                     prey, so that the resources of the earth are never idle. Some                     animals or plains may seem to dominate the rest, but they                     do so only so long as the general balance exists.<\/p>\n<p>These laws cannot be disregarded without disaster. Nature                     &#8211; which is our word for the total of the conditions and principles                     which influence the existence of living things &#8211; will not                     accept ignorance of her laws as an excuse for breaking them.<\/p>\n<p>Nature&#8217;s law does not command us to do, or to refrain from                     doing, anything. It merely states that if a living being does                     so-and-so, then the result will be such-and-such.                     If we wish to avoid disability, pain and dissolution, we must                     pay attention to the warning.<\/p>\n<p>Every balance requires checks. Living things are dynamic,                     always trying to expand. When population grows in an area                     so as to menace the food supply, predators move in; when their                     prey is reduced, the predators are driven to other areas in                     search of food.<\/p>\n<p>Before shying away from the &#8220;cruelty&#8221; of nature, let us                     look at the necessity which prompts it. Let us suppose there                     were no control over soil bacteria, the smallest and simplest                     of all living things. Then, says John H. Storer in his delightful                     book on ecology <em>The Web of Life<\/em>, under favourable conditions                     each individual would divide into two about twice every hour.                     Even if it happened only once in an hour, the offspring from                     a single individual would number 17 million in a day, and                     by the end of six days the cells would have increased to a                     bulk larger than the earth. Or consider the oyster, which                     may discharge 500 million ripe eggs in one spawning. If all                     these matured and all subsequent progeny survived, after only                     four generations there would be a pile of oysters eight times                     the size of the earth. The balance preserved by nature prevents                     calamities of this sort.<\/p>\n<h3>About soil and water<\/h3>\n<p>Good soil is a living thing, and its health is a matter                     of life and death to plants and animals. What folly it is                     to call silver, gold and gems &#8220;precious&#8221; and dirt &#8220;base&#8221;.                     If there were as great a scarcity of soil as there is of jewels                     and precious metals, we should gladly give a heap of diamonds                     to purchase only so much earth as would hold a small violet                     in a tiny pot.<\/p>\n<p>The soil is constantly changing. In the soil we find one                     of the oldest laws of life known to us: birth, growth, death,                     decay and rebirth.<\/p>\n<p>Nothing is wasted in nature. Everything nourishes something                     else until the bacteria finally get hold of it and return                     it to the soil after breaking it down once more into inorganic                     compounds which plants can again transform into protein. The                     roots of man&#8217;s physical and mental health spring from the                     soil.<\/p>\n<p>Soil is first of all rock particles, then the organic matter                     from dead plants and animals, and finally a community of living                     plant and animal organisms. Roots, insects, worms and bacteria                     build fertility into it, while small mammals plow it and let                     in the air. The soil becomes filled with organic matter containing                     packaged energy from the sun.<\/p>\n<p>The hive of living things existing in and on the soil is                     vitally important. At Rothamsted in England, the oldest agricultural                     research station in the world, it has been found that the                     population of invertebrate fauna per acre of fertilized land                     is fifteen million, of which eight million are insects.<\/p>\n<p>Water is essential to soil development, as it is, indeed,                     to all living things.<\/p>\n<p>Movement is of the essence of water, and the most damaging                     impact of civilized man on his environment is the shattering                     of this cycle of movement. The break is caused by the destruction                     of plant cover, removing the sponge-like texture of the                     complex topsoil &#8211; topsoil which, it is estimated, took five                     hundred years per inch to build.<\/p>\n<p>Breaking the water cycle has wiped out civilizations in                     Mesopotamia and North Africa and elsewhere, but because of                     soaring world population we have reached a new crisis. &#8220;Never                     before,&#8221; says William Vogt in his soul-searching book                     <em>Road to Survival<\/em>, &#8220;has the hydrologic cycle been badly                     dislocated in the presence of so many hundreds of millions                     of people.&#8221;<\/p>\n<p>Waste of water, including unnecessary run-off, or excessive                     use from any one place for industrial and domestic purposes,                     or for irrigation, can lower the underground water table,                     sometimes far away, and deplete or temporarily exhaust the                     supply.<\/p>\n<p>The primary means of increasing and maintaining water reserves                     is to protect and improve the plant cover on our watersheds.                     From these areas of drainage the water is fed by run-off                     and seepage to surface and underground streams.<\/p>\n<p>The watershed problem is one of the red-letter problems                     of the day. Almost everything that has to do with renewable                     natural resources, with forestry, farming, hunting, fishing,                     and the economics of production, is tied up with the watershed.<\/p>\n<h3>Plants and trees<\/h3>\n<p>It is quite correct to say that all flesh is grass. Animals                     lack the ability to subsist on the simple elements in air,                     water, sunshine and soil. To perpetuate themselves, they must                     eat grass or one another. The plant can turn inorganic chemicals                     into living tissue.<\/p>\n<p>No one can. deny, then, the importance of plant life to                     continuance of the human race. Without that silent, endless                     manufacturing process which goes on in the green leaf under                     the influence of chlorophyll, sunshine, air, and moisture                     &#8211; the world&#8217;s primal industry &#8211; we should surely die.<\/p>\n<p>Every spring, nature&#8217;s factory starts again to produce food,                     harnessing the sun&#8217;s energy and combining it with elements                     from air, water and rock, into living tissue. From the roots,                     through the fibres, the sap runs up, carrying water and nourishment                     to every part of the plant, and in the inside part of the                     bark it flows down, bringing the foodstuffs which the leaves                     have manufactured.<\/p>\n<p>Forests are living societies of trees, shrubs and other                     forms of plant cover. Although more than forty per cent of                     Canada&#8217;s surface is covered by trees, our people are becoming                     conscious of the need to conserve and expand our forest resources.<\/p>\n<p>Most industrial countries pass through the same three stages                     of forest history. The first is marked by energetic and often                     ruthless exploitation of virgin forests. This is generally                     followed by a period of increasing dependence on foreign supplies.                     Then the third chapter begins: the effort to rehabilitate                     or partially restore the domestic forest resources.<\/p>\n<p>Violation of the laws governing the extent of necessary                     forest cover is one of the most tragic examples of human folly                     in the face of nature&#8217;s well-ordered system. But it does                     us no good to place all the blame upon the pioneers. They                     did the thing that seemed right to them under their circumstances.                     If they denuded our watersheds with axe and fire, if they                     used the hoe and the plough where only trees could grow, they                     paid the price in their own lives through blasted hopes and                     abandoned farms and niggardly living. It is our part, knowing                     more of the interrelationships of all nature, to repair the                     damage where we can, and to make sure that such things do                     not occur again.<\/p>\n<h3>Importance of environment<\/h3>\n<p>What is environment, in the sense of &#8220;natural environment&#8221;?                     It includes all factors, natural and artificial, which affect                     the development of living things.<\/p>\n<p>Life is correspondence with environment. Different creatures                     seek different environments, but everything exists at a specific                     place under specific circumstances. As human beings, our greatest                     psychological asset is a sense of confidence in our environment.<\/p>\n<p>The carrying capacity, which is the measure of the amount                     of life any area of land or water will support under given                     circumstances, may be altered from time to time by changes                     in conditions caused by nature or by man&#8217;s use of the area.<\/p>\n<p>It sometimes happens that these changes lead to a precarious                     existence. The creatures in the area may seem to be leading                     a static life, but our environment is not a museum display                     case in which petrified groups are forever removed from contact                     with nature. Something is always happening, and just a little                     change, a little more severity, a little more depletion, may                     bring to an end the existence of groups or all the population.<\/p>\n<p>No one knows how many species during the ages failed to                     meet the challenge of their environment. George L. Clarke,                     of Harvard University and Woods Hole Oceanographic Institution,                     says in his textbook <em>Elements of Ecology <\/em>that about                     21,000 species of extinct vertebrates and an even larger number                     of extinct higher plants have been described.<\/p>\n<p>Today it is necessary for mankind to adjust its usage and                     to manage earth&#8217;s remaining resources more creatively if it                     is to survive. We see the warning in the life history of every                     forest. Trees such as oaks grow so big that their own seedlings                     cannot survive in their shade; the oak forest perishes, and                     is replaced by shade-tolerant trees like the beech, the                     maple and the hemlock. Then, as long as the present climate                     continues, this will remain a beech, maple or hemlock forest                     &#8211; a climax forest &#8211; because these trees have the ability to                     reproduce under their own shade.<\/p>\n<h3>Effects of human acts<\/h3>\n<p>It is a curious commentary on our sense of values that though                     we think of mankind as being the highest form of life the                     other forms of life almost invariably go into decline wherever                     we take possession of a piece of the earth.<\/p>\n<p>Civilized man has been more ruthlessly wasteful in his attitude                     toward the natural world than has served his material interests.                     The practical utility of land, water and forest has been diminished                     seriously by our determination to allow them to serve no purposes                     but our own. This exploitation led Maurice Maeterlinck, the                     Belgian dramatist and writer, to say: &#8220;Everything seems to                     foretell that man, the last comer to this earth, will be the                     first to leave it.&#8221;<\/p>\n<p>Through the use of his intellect, man has to some extent                     escaped from the controls of nature. He has meddled with small                     parts of a machine of whose total design and purpose he was                     ignorant. He now faces the hard task of encouraging natural                     forces to work in restoration of the damage he has done.<\/p>\n<p>Because of the danger attending ignorance, we need much                     more information about nature than we have yet gathered. Even                     well-meant efforts may bring disaster, as witness the                     experience with deer at Kaibab Forest, on the north rim of                     Grand Canyon. When, in an effort to increase the population                     of deer, the authorities killed off great numbers of mountain                     lions, coyotes, wolves and other predators, the deer population                     increased from 4,000 to 100,000 in fourteen years. The land                     did not have the carrying capacity for that huge number, and                     consumption of all the food was followed, in two years, by                     a sixty per cent reduction in the herd through starvation.<\/p>\n<p>Hunting and fishing, formerly practised for the food they                     yielded, are valued today chiefly for their recreational use.                     Once in a while we encounter something that is very far from                     sport, and we see the wilderness in its sourest mood. It is                     the rampage of a killer who wastes wildlife for what he calls                     a bag. He gets no satisfaction except that of saying &#8220;Something                     which wanted to live is dead.&#8221;<\/p>\n<p>The true sportsman knows the spirit of the outdoor world.                     He follows the rules of the game. He believes in and obeys                     laws which protect wildlife.<\/p>\n<p>One of the most repulsive of the destructive results of                     human expansion is the poisoning of rivers, with consequent                     extinction of fish and of well-nigh every living thing                     except mould and putrefactive bacteria.<\/p>\n<p>The fisheries of the lakes, ponds and streams are among                     our most important recreational resources. But our rivers                     are choked with the refuse of civilization. Our lakes are                     poisoned by industrial and sewage pollution. The water is                     dangerous to drink and risky to swim in; the plants are killed                     which should help to purify the water. Here and there across                     the continent municipalities are trying to stop the process                     of pollution. Several shipping companies have been prosecuted                     for dumping oil in our inland waterways, and a 50-mile                     zone off Newfoundland&#8217;s east coast has been declared a region                     in which oil may not be dumped.<\/p>\n<p>And now we are exercised about nuclear fallout. Its effect                     upon living things is a matter of debate, but there seems                     to be reason to believe that fallout will be like another                     influence superimposed upon all natural things.<\/p>\n<p>It is because of growing awareness of the vital need for                     knowledge and action that the first national Canadian conference                     on conservation is to be held next year. Its title is &#8220;Resources                     for Tomorrow.&#8221;<\/p>\n<h3>How is one to learn?<\/h3>\n<p>It is a great loss to travel the countryside and not see                     it, since contact with nature is a vital part of man&#8217;s enjoyment                     of life.<\/p>\n<p>Facts about nature may be read in books (like <em>The Ladder                     of Life <\/em>by A. Gowans Whyte and <em>The Great Chain of Life                     <\/em>by Joseph Wood Krutch, both introductory books) and seen                     on television (as in Dr. Ian McTaggart Cowan&#8217;s <em>Web of Life<\/em>,                     the Sunday CBC programme from Vancouver.) But after sampling                     in this way we will want to go into the woods and sit down.<\/p>\n<p>The centuries of dead leaves that have fluttered to the                     ground have provided a rich layer of mould, soft as any carpet,                     with an embroidery of wild flowers to make it beautiful. The                     drama being played among the trees is without end. In the                     tree tops the robins are singing their absurd but delicious                     little four-noted songs; saucy squirrels are gamboling                     in the branches; ants are scurrying among last year&#8217;s leaves                     on their mysterious errands.<\/p>\n<p>These children of nature are all straightforward creatures                     with very simple intentions, and every one is supplied with                     beauties of one kind or another. Watching them, we realize                     that the mystery of life is not a problem to be solved, but                     a reality to be experienced and preserved.<\/p>\n<p>Biologists are aware of the need to preserve nature&#8217;s balance,                     and of the techniques, but only public opinion nurtured amid                     such scenes can make the application of these procedures effective.                     There is no automatic force in nature which will carry human                     beings forward irrespective of their own efforts. We need                     a new creed to be stubbornly faithful to the facts of life;                     and a new determination &#8211; to contribute our effort in doing                     the right things.<\/p>\n<p>Our hope is in education. The problem is not as simple as                     two plus two, quickly answered and as readily disposed of.                     This is a problem for statesmanlike people who take a long                     view, who look not at the next vacation or the next balance                     sheet or the next election, but at the future of mankind.<\/p>\n<p>Since the beginning, the world has presented challenges                     to living creatures: to crawl out of the sea to live on dry                     land, to climb trees and mountains, to change in keeping with                     changing environment. Every creature is to itself the centre                     of its own universe, but it must have contact with all surrounding                     creatures. The challenge to us is nothing less than preservation                     of our species by restoring and maintaining its essential                     environment.<\/p>\n<p>We are surrounded by, and we are part of, the eternal flux                     of life in an environment of natural forces. An Eastern proverb                     puts it: &#8220;To survive, all men must hold hands.&#8221; And living                     things of all sorts are our kin in the wholeness of nature.<\/p>\n<p>If we wish to preserve our present way of life we must come                     to terms with what is left of natural forest, soil, water                     and wildlife, and it will be on terms laid down by nature,                     not imposed by us. Any wrong which nature may for centuries                     commit, she has centuries to repair, but we, whose days are                     short, must walk warily lest we become the victims of the                     wasteland we make.<\/p>\n<\/div>\n","protected":false},"author":79,"featured_media":0,"template":"","categories":[1],"rbc_letter_theme":[],"rbc_letter_year":[40],"class_list":["post-3976","rbc_letter","type-rbc_letter","status-publish","hentry","category-uncategorized","rbc_letter_year-40"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO Premium plugin v27.2 (Yoast SEO v27.2) - https:\/\/yoast.com\/product\/yoast-seo-premium-wordpress\/ -->\n<title>May 1960 - VOL. 41, No. 4 - The Relationship of Man and Nature - RBC<\/title>\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\n<link rel=\"canonical\" href=\"https:\/\/www.rbc.com\/en\/about-us\/history\/letter\/may-1960-vol-41-no-4-the-relationship-of-man-and-nature\/\" \/>\n<meta property=\"og:locale\" content=\"en_US\" \/>\n<meta property=\"og:type\" content=\"article\" \/>\n<meta property=\"og:title\" content=\"May 1960 - VOL. 41, No. 4 - The Relationship of Man and Nature - RBC\" \/>\n<meta property=\"og:description\" content=\"To subdue nature, to bend its forces to our will, has been the acknowledged purpose of mankind since human life began, but the time has come for a revision of our conception of the benefits and responsibilities of holding dominion over all other created things.
