In the past, man did not have to think about protection of the environment. There were very 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 land. Yet, we continue to use more powerful machines to cut down more and more trees.
We realize that if rivers are polluted with waste products from factories, we will die. However, in most countries waste is still put into rivers, but there are few laws to stop this.
We also know that if the population of the countries in the world is to rise 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 available for everyone. Land that is used to grow crops can feed five times more people than land where animals are kept.
Our natural resources will last longer if we learn to recycle them.
The world population will not rise so quickly if people use modern methods of birth control.
Finally, if all of us think about the problem, we will have a better and cleaner planet in the future

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.

down, forests will disappear and nothing will grow on land. Yet, we continue to use more powerful
machines to cut down more and more trees.

national park is to protect the plants and animals that live there. But things that happen outside the park
also affect the life within it.
Everglades National Park is part of a much larger area known as the Everglades. At one time, water
flowed freely in the Everglades. During the rainy season, water would fill the Kissimmee River. Then it
flowed into Lake Okeechobee. Once the lake became full, water spilled over onto the flatland. From there
a shallow sheet of water moved slowly down the Florida Peninsula. Then it emptied into Florida Bay. This
shallow sheet of water was the Everglades River. It was only a few inches deep. But it was up t0 50 miles
wide and over 100 miles long.
The Everglades is home to many plants and animals found nowhere else in the world. Today, some of
these plants and animals are in danger of disappearing forever.
The main reason is that the Everglades is no longer a free-flowing river. Canals have been built to drain
(排干) most of the shallow river. People have also built a dam to hold back water from Lake Okeechobee.
Most of the water from the Everglades is trapped in man-made lakes. Cutting off the flow of water into
Everglades National Park has done more harm than good. Now it threatens the wildlife in the park.
Water pollution is another reason some plants and animals are disappearing. Years ago, large areas of the
Everglades were drained and turned into farmland. Today the fertilizers (肥料) used on crops are polluting
the water. The "river of grass" is slowly disappearing. Many kinds of plants are disappearing. Animals that
depend on these plants for food no longer have anything to eat.
The problems facing Everglades National Park are very serious. But there is still hope. Work is already
under way to save the Everglades. The federal government, the state of Florida, and several other groups
are all working together to try to undo the damage.
B. To protect the plants and animals.
C. To provide a fun place for people.
D. To keep animals from going in the park.
B. how big Everglades River was
C. what the Everglades used to be like
D. what happened to Everglades River during the rainy season
B. people cut the plants that the animals feed on
C. large areas of Everglades were turned into buildings
D. the water flowing into the Everglades has been cut off
B. some measures are being taken to protect the environment of Everglades
C. the environment of Everglades will be worse and worse
D. the government is worried about Everglades but has no way
