Talk about the meaning of the topic Silent Spring according to the text.

"Silent spring" means that human abuse of chemical drugs will kill insects, endanger the survival of other creatures on earth and even human beings, and eventually lead to the terrible scene of "birds don't sing and fish don't jump" in spring. The author takes this opportunity to solemnly warn the world that the abuse of chemical drugs will destroy the natural ecology, and human beings will be strongly retaliated by nature, leading to their own disasters.

The specific scene of Silent Spring can be fully imagined by students, and can also be described with some examples of serious ecological damage caused by environmental pollution in real life.

The Fable of Tomorrow (Chapter 1 of Silent Spring)

Once upon a time, there was a small town in the middle of the United States, where all living things seemed to live in harmony with their surroundings. The town is located in the middle of a prosperous farm, neatly arranged like a chessboard, surrounded by crops and orchards at the foot of the mountain. In spring, flowers are dotted on the green Yuan Ye like white clouds; In autumn, through the screen of the pine forest, oaks, maples, and birch trees flash with flame-like colorful brilliance, foxes sing on the hills, and deer quietly pass through Yuan Ye shrouded in autumn morning fog.

Laurels and poplars growing along the road, as well as huge ferns and wild flowers, make travelers happy for most of the year. Even in winter, there are beautiful places on both sides of the road, where countless birds fly around and peck at berries and hay heads exposed on the snow. In fact, the suburbs are famous for their colorful birds. Throughout the spring and autumn, when migratory birds flock, people come here not far from Wan Li to watch. Others came to the stream to fish. These clean and cool streams flow out of the mountains and form a pond, where trout live in the shade. The field has always been like this, until one day many years ago, the first residents came here to build houses, dig wells and build warehouses, and the situation changed.

Since then, a strange shadow has enveloped this area and everything has begun to change. There were some ominous signs in the village: mysterious diseases attacked flocks of chickens; Cattle and sheep got sick and died. The spectre of death is everywhere. Farmers talk about their families' diseases. Doctors in this city are more and more confused about the new diseases among patients. There are some sudden and unexplained deaths not only among adults but also among children. These children suddenly fell down while playing and died within a few hours.

A strange silence hung over the place. For example, where have all the birds gone? Many people are confused and uneasy when they talk about them. A place where birds feed after the garden is deserted. Some birds that can only be seen in some places are also endangered. They tremble so much that they can't fly. This is a silent spring. There used to be crows, thrushes, pigeons, ostriches, wrens and other birds singing in the early morning; There is no sound now, only silence covers the fields, Woods and wilderness.

The hens on the farm are hatching eggs, but no chicks have hatched. Farmers complain that they can no longer raise pigs-the newborn piglets are very small and can only live for a few days after illness. The apple flower is about to bloom, but there are no bees buzzing in the flower, so the apple flower is not pollinated and will not bear fruit.

On both sides of the once attractive path, there are now plants that seem to be burnt and withered after the fire. These places abandoned by life are also silent. Even the stream lost its life; Fishermen don't go there anymore because all the fish are dead.

In the rainwater pipes under the eaves and between the tiles on the roof, a mass of white powder is still showing a little spots. A few weeks ago, these white powder particles landed on roofs, lawns, fields and rivers like snowflakes.

It is not magic, nor the enemy's activities that make life in this destroyed world impossible to revive, but people themselves make themselves miserable.

The above-mentioned town is fictional, but thousands of copies of it can be easily found in the United States and other parts of the world. I know that no village has suffered all the disasters I have described; But these disasters actually happened in some places, and indeed many villages suffered great losses. In people's neglect, a ferocious ghost came to us. This imaginary tragedy may easily become a living reality, and all of us will know it.
