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 world's 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 world's 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 don't 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.

Let's unite together, hand in hand we stand all across the land.

We can make this world in which to live. Hand in hand. Control the population growth. Take good care of our nature.

tips for happinein daily life

daily life can be made happier. it is a matter of choice. it is our attitude that makes us feel happy or unhappy. it is true, we meet all kinds of situations during the day, and some of them may not be conductive to happiness. we can choose to keep thinking about the unhappy events, and we can choose to refuse to think about them, and instead, relish the happy moments. all of us constantly go through various situations and circumstances, but we do not have to let them influence our reactions and feelings.

if we let outer events influence our moods, we become their slaves. we lose our freedom. we let our happinebe determined by outer forces. on the other hand, we can free ourselves from outer influences. we can choose to be happy, and we can do a lot to add happineto our lives.

what is happiness? it is a feeling of inner peace and satisfaction. it is usually experienced when there are no worries, fears or obsessing thoughts, and this usually happens, when we do something we love to do or when we get, win, gain or achieve something that we value. it seems to be the outcome of positive events, but it actually comes from the inside, triggered by outer events.

for most people happineseems fleeting, because they let changing outer circumstances affect it. one of the best ways to keep it, is by gaining inner peace through daily meditation. as the mind becomes more peaceful, it becomes easier to choose the happinehabit.

here are a few tips for increasing happinein daily life:

1) endeavor to change the way you look at things. always look at the bright side. the mind may drag you to think about negativity and difficulties. don't let it. look at the good and positive side of every situation.

2) think of solutions, not problems.

3) listen to relaxing, uplifting music.

4) watch funny comedies that make you laugh.

5) each day, devote some time to reading a few pages of an inspiring book or article.

6) watch your thoughts. whenever you catch yourself thinking negative thoughts, start thinking of pleasant things.

7) always look at what you have done and not at what you haven't.

as people’s thoughts control their bodies, computer programs play a leading role in the modern times. both social progress and human evolution depend on the computer programs. in the practical application, a software consists of different programs and then combines with hardware to develop into a high-tech electronic product. there are many kinds of electronic products found everywhere in our daily life. nearly all the time do we make use of these products to conduct our passion.

yes, it is definitely right that programming is a hard work because of its special characteristics---complicated, time-wasted, logical. to make a program needs our continual patient and confidence, and we should accept failure again and again in most cases. but once you go into further understanding of computer programs, you will be surprised at the programs’ wander. in detail, through programming a heap of date or a computing model can be easily solved we expected, such as a number wanted, or the model’s parameters. the magical power of program appeals to all the programmers, certainly including me.

it is of great convenience for us to simplify or model our complex questions by programming. furthermore, studying and using programs can enforce us to form our ability of analyzing and logic. computer language has its regular grammar. how to organize the language into a reasonable calculating method in a high efficiency like speaking easy-understanding and breath-saving words, is an awful challenge for us, and it will be very funny.

now, software is more and more important in our life, therefore programmer becomes a popular profession, which is one urgent need in the society. for our country, it’s very important to ensure our national security from others, such as japan. enhancing military strength makes us pay more attention to the informationalized war that attached intensely to the fundamental function of program and software. it is truth that china has a huge population of 1.4 billion, which means messy things from all the people every day. also, to govern the society orderly all benefit from information composed by programs.

take a more closer example, in the classroom, we are graduate students of engineering, and will be occupied in researching and designing work. thus, not only is programming our tool in study, but also become a weapon that promoting science and technology and producing invention and innovation.
