In the introduction to “Silent Spring” written by Rachel Carson in 1962, more than 50 years ago, the writer attempts to warn us that humans will eventually destroy the earth in the opening quote. It shows that humans are causing harmful effects to the environment and the environment is being polluted day by day. First of all, to get to the problem, the author starts from a fairy tale. It describes a beautiful natural city, but then the appearance of humans brought strange ruin and everything began to change. Quiet, sickness, disease and death emerged in the city. Although the city in this story is not a reality, the events in this city are really happening all over the world. The author uses points throughout the book's introduction to explain and support the main idea. Time is one of the important themes in this reading. He says that “time is not in years but in millennia”, it took a long time to produce the life that now inhabits the earth, because life adapts and balance has been achieved. However, the earth changes rapidly due to man's impetuous and distracted pace. People bring toxic substances to the earth that would take time, on the scale and lifetimes of generations, to fix these things. People create chemical substances, synthetic materials which, when introduced together with radiation, damage the environment and organisms. Toxic productions are introduced into the environment but people hardly know the devils they have created. These productions cause negative effects such as vegetation death, livestock disease and air pollution. People use chemicals to control insects, but this method has had only limited success. Day after day, insects adapt these chemicals to survive, becoming stronger and more difficult to control. Eventually, the chemicals leak. The writer also says that monoculture (single crop agricultural system) does not exploit the principles by which nature works, people are simplifying nature which introduced variety. Rachel Carson suggests using polyculture (growing many crops in one field) 50 years ago. People also face the modern insect problem. Due to isolation from one continent to another, insects have developed many new species. These species have begun to move to new territories that receive considerable help from humans. Although people know the necessary knowledge - chemicals and synthetics are harmful to the earth and humans - but they do not use them.
