英语作文：The Problem of Human Population

　　it has been estimated that a thousand years ago there were less than 400 million people on earth. today, however, the world's population has amounted to 5,000 million. what is worse, it keeps growing at a surprising speed. if this trend continues, the world's population will shoot up to 7,000 million by the year xx. this is what we call population explosion.

　　the rapid development of science and technology is the main cause of population explosion. we can see that the population has been growing at a tremendous speed since the industrial and agriculture revolution in 1650, which raised the people's standard of living, and the emergence of modern medicine in 1550, which lowered the people's death rate.

　　population explosion will result in a lot of such problems as food shortage, housing shortage and unemployment. it is time that we acted quickly to carry out the policy of birth control otherwise, man's survival on the earth will be threatened.

　　It is a commonplace among moralists that you cannot get happiness by pursuing it. This is only true if you pursue it unwisely. Gamblers at Monte Carlo are pursuing money, and most of them lose it instead, but there are other ways of pursuing money, which often succeed. So it is with happiness. If you pursue it by means of drink, you are forgetting the hangover. Epicurus pursued it by living only in congenial society and eating only dry bread, supplemented by a little cheese on feast days. His method proved successful in his case, but he was a valetudinarian, and most people would need something more vigorous. For most people, the pursuit of happiness, unless supplemented in various ways, is too abstract and theoretical to be adequate as a personal rule of life. But I think that whatever personal rule of life you may choose it should not, except in rare and heroic cases, be incompatible with happiness. If you look around at the men and women whom you can call happy, you will see that they all have certain things in common.

　　The most important of these things is an activity which at most gradually builds up something that you are glad to see coming into existence. Women who take an instinctive pleasure in their children can get this kind of satisfaction out of bringing up a family. Artists and authors and men of science get happiness in this way if their own work seems good to them. But there are many humbler forms of the same kind of pleasure. Many men who spend their working life in the city devote their weekends to voluntary and unremunerated toil in their gardens, and when the spring comes, they experience all the joys of having created beauty. The whole subject of happiness has, in my opinion, been treated too solemnly.

　　It had been thought that man cannot be happy without a theory of life or a religion. Perhaps those who have been rendered unhappy by a bad theory may need a better theory to help them to recover, just as you may need a tonic when you have been ill. But when things are normal a man should be healthy without a tonic and happy without a theory. It is the simple things that really matter. If a man delights in his wife and children, has success in work, and finds pleasure in the alternation of day and night, spring and autumn, he will be happy whatever his philosophy may be. If, on the other hand, he finds his wife fateful, his childrens noise unendurable, and the office a nightmare; if in the daytime he longs for night, and at night sighs for the light of day, then what he needs is not a new philosophy but a new regimen--a different diet, or more exercise, or what not. Man is an animal, and his happiness depends on his physiology more than he likes to think. This is a humble conclusion, but I cannot make myself disbelieve it. Unhappy businessmen, I am convinced, would increase their happiness more by walking six miles every day than by any conceivable change of philosophy.
