Everything grows in modern times, and it seems that nothing grows as quickly as population. Population keeps growing, and grows rapidly, firstly because peoples living standards keep going up, with better houses, better clothing, better food, secondly because people know how to preserve themselves so as to live longer, and thirdly
because they have modern medicine and medical care to ensure that usual diseases can be easily cured. There is another cause for the growth of population. Few countries or governments have realised the importance of family planning. On the contrary, some encourage child-birth.
Here are some examples of population growth from 1985 to 2000 (as anticipated).
Lima had 5.7 million people in 1985 but there were 9.1 million by 2000. Tianjin used to have 7. 9 million in 1985. By 2000 its population reached 9. 7 million. Such cities as London, Osaka, Moscow, Beijing, Karachi, Delhi, Jakarta, Seoul, and Teheran are having a similar population growth. We would not be shocked if all other cities have this rate. But some cities, like Calcutta, Shanghai, New York, and Sto Paulo boost their population even more quickly than the above-mentioned cities. Tokyo had 18.8 million in 1985. The year 2000 found 20.2 million Tokyo citizens. Mexico city had 17.3 million people in 1985, but as population specialists had predicted, that reached 25.8 million in 2000 !
The population problem is a universal concern nowadays. Any government is a failure if it does nothing about its population growth.
Family planning is the most effective way to solve the population problem, the seriousness of which we often underestimate.
Quite obviously family planning has so far macle little progress. At a time when half of the world is suffering from starvation, poor health and a badly Iow standard of living, we simply cannot take lightly the population problem. If we dont control the birth rate right now well surely lead a miserable life in the near future.llliteracy is perhaps the main enemy of family planning.Countries, which share the highest birth rate such as Brazil and India, are also those which share the highest illiteracy rate. People there dont even know what birth control is.
To me, the ignorance of family planning is a social problem. So we had better begin with social reforms through,say, legislation, etc. Of course, we cannot deny the necessity of the medical approach and we should use it in conjunction with other methods. The answer to the question whether man can survive one of the crises of the 21st century, namely population, is in our hands.
From these graphs, we can draw a conclusion that, with the growth of human population, the number of species has decreased rapidly in America, and some species have even vanished from our planet.
Why does this phenomenon appear? There are several possible reasons for this. Above all, as the human population grows rapidly, a growing number of people came to live where some wild species have been living. Then these species have to move to other places. Some of them probably can not adapt to the new environment and die. In addition, although many people look on the wildlife as their friends, some people may not think so. They catch a lot of wild animals and sell them in order to get more money. Even worse/More importantly, as the result /consequence of the industry, the natural balance and the ecologic environment are destroyed. The clear cutting has become increasingly serious. So some of the wildlife become homeless and extinct.
In order to protect the wildlife, I have some suggestions. First, the governments should make laws to prevent them from being caught and killed. Second, the governments should educate people to love nature and protect it. Third, as for ourselves, we should take practical actions to protect our living environment.
