After reading the passage clip of the novel-Silent Spring, what do you get from the passage?

【参考范文】

Silent Spring is her representative work which lighted the fire of environmental protection in America and the whole world. Before 1960s, no books or magazines talked about things like environment and ecosystem. Such a phenomenon means that environmental protection had not come to people’s mind and the social consciousness. Indeed, the main opinion in human society from the very past about nature is to “set war against” or “conquer” it. In fact, many of human’s progresses are made on the base of such opinion. Rachel Carson was the first person who doubted the correctness of the belief and brought the topic under focus.

Carson is a great woman and fighter. When writing the book, she was suffering from huge pain of the operation for mammary cancer. After the book was published, the widely affect brought her not honor and fortune, but fierce attack from the chemical estate. She died only one year after the book’s publishing. On the spring of 1964, the great woman passed away, but Silent Spring made her voice never silent.

The 20st century was a time that technology and economy developed rapidly, especially the 40 years after Silent Spring was published. But every spring, when flowers bloom, trees sprout, and water begins to flow, we used to recall a woman and her enduring works. We opened the window, and wonder if the spring is silent today, if it will be silent tomorrow.

We are facing a very serious ecological problem, and we must do everything possible to keep out water and air clean; to protect our land and soil; to preserve out forests, rivers and lakes, marshland, wilderness; to stop the global warming; and to save the endangered species, people now generally agree that we should not develop our economy at the expense of our ecosystem. We must aim at a sustainable growth. We should contribute to environmental protection from now.
