Television viewing is a major activity and influence on children. Children in the United States watch an average of three to four hours of television a day.
While television can entertain, inform, and keep our children company, it may also influence them in undesirable ways. Time spent watching television takes away from important activities such as reading, school work, playing, exercise, family interaction, and social development. Children who watch a lot of television are likely to have lower grades in school, read fewer books, exercise less, and be overweight.
Parents can help by doing the following:
♦ Don’t allow children to watch long blocks of TV.
♦ Help them choose suitable programmes. Children’s shows on public TV are appropriate, but soap operas, adult sitcoms and adult talk shows are not.
♦ Set certain periods when the television will be off. Study times are for learning, not for sitting in front of the TV doing homework.
Make TV viewing an active process for child and parent!

Earth where our human living on are the third planet in the Solar System. It carried almost 7 billions human beings, other billion life forms such as animal, trees or even bacteria. It was the best planet for human to live on where far enough to our Sun, so all life won't be frozen or close enough, so we won't be burned and dead. However, we are destroying it so badly and making it become difficult to live by releasing the harmful substances to environment. So far, Earth is still the best choice for human beings to live in this Milky Way.With the increasing of polution, food crisis, rising of Global Warming or any disarters which are out of human control, it might be risky for the human life on Earth. Definitely it is necessary for human to find other planets to live in order to avoid human extinction which absolutely will be happening in the future.with the development of advanced technology, we might control the natural desarters. But, it will only happen in the future which we are unable to figure out. So, finding new planets for our next generation should be the first priority misson for current generation in order to keep the human values spreading endlessly.
It is true, that if present trends continue, it will become increasingly difficult to sustain human life on Earth. While I agree that it is vital to tackle this problem. I believe that expenditure on research for new planets to colonise should be given a low priority, and resources must be used to find other, more practical solutions.There are two major reasons why life on Earth is becoming more and more unsustainable. One obvious problem is the uncontrolled consumption of natural resources, which are being depleted as a result. For instance, the extraction of fossil fuels, such as coal, gas and oil to satisfy growing energy demands has serious environmental impacts, and these resources will eventually run out. Another concern is the rising level of pollution worldwide, of the land, the oceans and the air that we breathe. In India, for example, thousands of tons of industrial rubbish have been released illegally into rivers, killing aquatic life and contaminating drinking water.However, I would argue that the search for a new planet on which humans could survive is a waste of valuable resources. Firstly, a vast amount of funding would be required to finance such space exploration, with no guarantee of success. This money is needed now to improve health services globally and to provide better education for all. Secondly, financial resources should be used to develop advanced technologies that would be more environmentally- friendly and provide renew able energy. In the field of transport, to take a simple example, vehicles can now be converted to run on hydrogen or even waste cooking oil – as McDonald’s have done with their trucks.
In conclusion, I consider that the search for new planets on which to settle is a waste of time and resources, and efforts should be concentrated on living more sustainably here on Earth.
