On the other hand， 4.the development of modern science and technology, man is just beginning to learn about wildlife.For example, 5. wild rubber trees had been extinct two centuries ago, there would be no auto 6.(industrial) today. Moreover，wildlife preserves unknown genetic codes，which may turn out to be a vital 7. (important) and free human beings from fatal diseases and natural disasters in the future.

Raising a baby takes a lot of work, especially when that baby is a king penguin. Now, it looks like climate change will make life even harder for these birds.
Most king penguins live on the Crozet Archipelago, a group of islands in the Indian Ocean, about 1，000 miles north of Antarctica. After the penguin chicks are born in November，which is summer in the Southern Hemisphere，both parents spend 4 months collecting fish to feed their offspring (后代)．
When the fish move to deeper waters in March, the adults swim hundreds of miles south. There, near the Antarctic ice, they spend the winter eating seafood to add to their own energy stores. In October, the parents return to their babies and finish raising them.
Scientists from France have been studying king penguins for a decade. Starting in 1998，Yvon Le Maho and his colleagues put electronic ID tags under the skin of hundreds of penguins. These are the same types of tags you might put in your dog or cat so that you can track them if they're lost. The tags have allowed researchers to get everything about penguins, such as how long they live, whether they return from their winter trips, and if their babies manage to survive the winter.
To see whether water temperatures affect the penguins, Le Maho compared his data with temperature records. Ocean surface temperatures vary from year to year. And previous research had shown that fewer fish and other creatures grow when the water is warmer. Le Maho suspected that this drop would make it harder for adult penguins to survive the hard times ahead. Indeed, his results showed that fewer adults survived during winters when the water was especially warm.
King penguins can live for up to 30 years. And for now, the population still appears healthy. But a warming trend could spell big trouble for a bird that depends on cold and ice.

In the past，man did not have to think about the protection of his environment.There were few people on the earth，and natural resources seemed to be unlimited.Today things are different.The world has become too crowded.We are using up our natural resources too quickly，and at the same time we are polluting our environment with dangerous chemicals.If we continue to do this，human life on the earth will not survive.
Everyone realizes today that if too many fish are taken from the sea，there will soon be none left.Yet，with modern fishing methods，more and more fish are caught.We know that if too many trees are cut down，forests will disappear and nothing will grow on the land.Yet，we continue to cut down more and more trees.We realize that if rivers are polluted with waste from factories，we will die.However，in most countries waste is still put into the rivers or the seas and there are few laws to stop this.We know，too，that if the population of the countries is rising at the present rate，in a few years，there will not be enough food.What can we do to solve these problems?
If we eat more vegetables and less meat，there will be more food for everyone.Land that is used to grow crops can feed five times more people than land where animals are kept.
Finally，if we educate people to think about the problems，we shall have a better and cleaner planet in the future.
