可持续发展英语四级作文 篇1
How can we meet the needs of today without diminishing the capacity of future generations to meet theirs? Sustainable development implies a broad view
of human welfare, a long term perspective about social development. Write an essay which should cover:
1) describing the set of drawings below,
2) stating its main idea, and
3) giving your comment.
The images above are both meaningful and instructive: this mans hard work is not only for his own benefit, but also for the benefit of future generations.
The pictures serve to remind us that the existence of our current happiness and valuable national heritage is due to the struggles of our predecessors.
We, in turn, should also work hard in order to guarantee the comfort and safety of generations to come. Sustainable development has become a topic of heated debate in recent years. While it is justifiable to satisfy current demands, we cannot neglect the needs of our descendants in the process. Our children also depend on Earths natural resources and we should not deprive them of such necessities.
Unfortunately, many people only think of their short term, personal interests. An entire forest might be clear cut, in the interest of making a profit, without a single tree planted in its place. This inconsiderate attitude towards the welfare of our descendants, as well the indifference to the outcome of such reckless actions, can only turn Earth into a cold and lifeless planet. People must be taught to appreciate Earth as not only their home, but also the home of our children and grandchildren, as well as all other plants and animals.

Sustainable development of tourism
Nowadays, tourism has become the most powerful development industry in many countries. It meets the tourist demand and promotes socio-economic and cultural development. But, at the same time, it also produces a negative impact on environmental resources, and has caused serious environmental damage, led to the tourism resources gradually degraded or disappeared. what’s more, this crisis has also deeply related to social, cultural, economic and psychological and so on. For example, water pollution caused by sewage and solid waste, which emissions by the hotels and other tourist service facilities; the air pollution results from the excessive use of modern means of transport in tourism activities. Sustainable Tourism stressed the moderate development of tourism resources, and the intra-generational equity and intergenerational equity, based on the combination of immediate and long-term interests.

protecting tourism environment can accelerate the growth of tourism. And this requires that people must be thoroughly the traditional values ,and improve the tourism developers、managers and tourists awareness of environmental protection, so as to promote the in-depth and sustained development of sustainable tourism.
Second ，setting up a specialized convention to regulate the development of sustainable tourism. International community should make special global environmental convention to deal with this question by drawing lessons from existing regional convention. This is the only effective legal measure to promote sustainable tourism development.
Finally, optimizing the structure of tourism industry. By this, We can promote the tourism development. In order to promote suitable development of tourist-area ,How to optimize
tourist-system is a very great task of tourism-study. Some eco-principles can provide useful ways and especial angels to the problem's settlement.
In addition , the trend of tourism and the market demand of tourism also are the important factors that influence the direction of the tourist resources exploration. Therefore, we must explore the tourist resources to meet market demand and keep up with the trend of tourism to promote tourism sustainable development.

tourism. We shall bring up tourism as an important industry in China's national economy, properly protect and utilize our tourism resources and try to achieve sustainable tourism development.

The idea of sustainable development has been accepted by the world. How to keep sustainable development is a big problem facing our planet.
The present situation is worrying. First，natural resources are becoming less than before. Second，as some people are not aware of the importance of the environmental protection，the problems with it remain extremely serious to some degree. The gap between the rich and the poor has the tendency to become wider and wider.
To our great joy，many countries have taken action. On one hand，they have made relevant laws and regulations and put large amounts of money to the environmental protection. On the other hand，popularized education as well as international cooperation is being carried out.
As for myself，I should take the responsibility to devote myself to sustainable development，our future and the lives of our children and our grandchildren will be in danger.

Healthier Grass, More Profits for Cattle Ranchers
Grasslands cover one third of the Earth’s surface. Grasslands are known by many names, such as savannah, prairie, steppes or the plains.
The health of grasslands depends on how much animals graze on the native plants. If too many animals feed on the plants, the area could become a desert. But too little grazing can also be bad for grasslands.
The Great Plains covers a large area in the middle of the United States. A lot of it is grasslands. The Great Plains are west of the Mississippi River and east of the Rocky Mountains. The area includes parts of 10 states.
The Great Plains are known for supporting large cattle ranches. A growing number of environmental groups are joining with local ranchers to improve the health of grasslands and make their businesses more profitable.
That is the sound of the wind blowing native grasses in Niobrara Valley of Nebraska.
Steve Hicks directs the Niobrara Wildlife Refuge for the U.S. Fish and Wildlife Service. One of its goals is to protect native plants and animals.
“The habitat diversity here is really pretty incredible.”
Song birds, small animals, elk, deer and American bison live in the grasslands.
“The bison are part of our purpose here at Fort Niobrara Refuge, and we’re supposed to provide a good habitat for them.”
Three hundred years ago, 20-million bison lived on prairies that covered most of what is now the American Midwest. The bison traveled thousands of kilometers each year, seeking food and fleeing other animals that hunted them. Their grazing helped the grasslands stay healthy. Their waste also helped the plants grow. And because the bison did not stay in one area for very long, grasslands had time to recover.
Today, the country has only about 30,000 wild bison. They mostly live in fenced-in areas on public land.
Fort Niobrara raises 350 bison on 9,000 hectares. Steve Hicks says it is not easy to control the large animals.
“And bison are manageable, but it’s a lot bigger job to keep bison contained than it is cattle. They’ll go just about where they want, if they really want to.”
The Fish and Wildlife Service also lets cattle ranchers use about 25,000 hectares of the government’s land.
One recent day, rancher Bob Grabher and a few other men were moving about 500 cows and their calves.
The men were riding on small vehicles near the bison. They used a combination of methods to get the animals out of a 200-hectare fenced pasture where they have been grazing for a few days.
“The refuge sets it up and gives you what pastures you will be in and how many days here in each pasture.”
The Niobrara Wildlife Refuge asks ranchers to graze their animals on the grasslands as the wild bison did hundreds of years ago. So Bob Grabher’s team moved the cattle to another fenced area that hasn’t been touched for three years.
Dean Churchill is Mr. Grabher’s son. He said that the ranchers can raise more cattle because they are able to lease land from the government. The animals never graze a pasture continuously. But the ranchers often let them stay in one area for two weeks. And instead of letting a pasture rest for years, they often bring cattle back within a few months. Mr. Churchill said this can help improve the grass.
“It adds compaction to the soil; the hoof prints within the soil allows the moisture to penetrate the soil better.”
Mr. Churchill says he learned these “planned grazing” techniques 20 years ago from Allan Savory. Today, the Savory Institute trains ranchers around the world to use planned grazing. The institute’s Byron Shelton says it is important for ranchers to know when to move their cattle.
“Once it’s bitten, no matter how far down its eaten, if it starts to re-grow, we move the animals away until it has re-grown. And that way we have the roots being the strongest they can to hold soil, hold water, make the ecosystem function."
The environmental group Nature Conservancy works with the Savory Institute. William Burnidge is Nature Conservancy’s Colorado Grasslands Program Director. He says a three-year-long experiment showed them how to graze more cattle and create a more diverse habitat.
“And at the same time we’ve improved the financial outcomes for ourselves and for our lessee at the ranch, and his quality of life I think has credibly improved.”
