To the nature,overpopulation is a big problem.More people,more pollution.And the big population is threatening the nature every second.
The rapid rise in world population is not creating problems only for the developing countries.The whole world faces the problem that raw materials are being used up at an increasing rate and food production can not keep up with the population increase.People in rich countries make the heaviest demands on the worlds resources,its food,fuel and land,and cause the most pollution.A baby born in the United States will use in his lifetime 30 times more of the worlds resources than a baby born in India.Unless all the countries of the world take united action to deal with the population explosion there will be more and more people fighting for a share of less and less land,food and fuel,and the future will bring poverty,misery and war to us all.
For most of the developing countries,it is a good idea to control the population growth.For example,China has carried out birth control for years.And this plan has a great effect on the world population.
If the population continues to increase,if the air and water continue to be polluted,if we dont do something to protect wild-plant and wildlife species will be declining.Species and biological communities have difficulty adapting to change.Economic opportunities and the quality of life of future generations are also put at risk.By protecting nature,we protect ourselves.
Lets unite together,hand in hand we stand all across the land.

A Young Idler,An Old Beggar.
Almost everyone knows the famous Chinese saying：A young idler，an old beggar. Throughout history，we have seen many cases in which this saying has again and again proved to be true.
It goes without saying that the youth is the best time of life，during which one's mental and physical states are at their peaks. It takes relatively less time and pains to learn or accept new things in a world full of changes and rapid developments. In addition，one is less likely to be under great pressure from career，family and health problems when young. Therefore，a fresh mind plus enormous energy will ensure success in different aspects of life.
Of course，we all know：no pains，no gains. If we don't make every effort to make good use of the advantages youth brings us，it is impossible to achieve any goals. As students，we should now try our best to learn all the subjects well so that we can be well prepared for the challenges that we will face in the future.
