' The Excerpt From Rachel Carson's Silent Springs

The excerpt from Rachel Carson’s Silent Springs explains how the human race has used their powers to alter the natural environment. These changes resulted in adverse effects, not only to organisms, but also to mankind. According to the extract, for many decades, life on Earth has been characterized by balanced interaction between the living organisms and the surrounding. The environment controlled the animal life habits and physical forms of vegetation. The situation has changed over time, and now people possess significant powers to change the environment. Human activities has increased to alarming levels in the past quarter century. Such powers have resulted in the contamination of the environment to a great extent: dangerous and even lethal materials are released into the air while others are disposed of in lakes and oceans, resulting in pollution. The pollution causes

irreversible effects on the living tissue.
Moreover, chemical release into the environment is the primary causes of changes in nature in the current world. Chemicals such as Strontium 90 are released into the air mostly through the nuclear explosion and then come back to Earth's surface through rains. Strontium remains in the soil until plants take it up and then it finds its way into the human or animal body, it stays there until death. Likewise, chemicals sprayed on croplands also affect the environment because they find their way into the air or water bodies. Once in the environment, these chemicals affect living organisms in different ways.
Furthermore, It took a million years for the biodiversity to be achieved on the Earth's surface. The atmosphere contained both harmful and essential elements that existed together. The environment rigorously shaped the life on Earth. It took ages for the environment to eliminate hostile conditions such as rocks that emitted radiation when exposed to light from the sun. Time was an essential factor that allowed the environment to remove any harmful conditions. Nowadays, the environment is not given time to achieve balance due to mankind’s’ activities.
New situations escalate quickly and nature is not given the opportunity to adjust the environment. For instance, people create radiation that occurred naturally from rocks due to the action of sunlight by tampering with atoms. Traditionally, environment would adjust itself naturally through the use of chemicals such as calcium, silica, and copper, but today the adjustment depends on the minerals created by scientists in laboratories. It is true that human beings have interfered with natural processes that control the environment, but the interference normally has an irreversible effect on life on the Earth's surface.
Unfortunately, the human race remains insensitive to the chemicals that are released in the environment each year.

An example of this would be is the number of new chemicals that are released into the environment exceeds 500 in the United States alone; plants, animals, and humans are expected to cope with all these chemicals. Some of these chemicals are so strong that living organisms cannot tolerate them; therefore, they end up killing or negatively harming the organisms. Among the killer chemicals released into the environment are the pesticides and insecticides that are used in our daily lives, Rachel Carson asserts that they should be defined as biocides because they affect all forms of life. The constant use of chemical results in the application of Darwinian’s principle of the survival for the fittest: the most resistant organism emerges. People respond by developing deadlier chemicals that harm the environment further. To sum up, the increased use of the chemicals in the field of entomology has more negative impacts on the environment and life on Earth than the benefits it

brings.
I concur with Carson’s views on how the human race is harming the environment. A significant number of harmful chemicals has been manufactured and released into the environment, especially pesticides and insecticides. Human activities have led to the creation of industries that allow numerous of harmful chemicals in the air. The owners of these industries are not concerned about the dangers posed by the chemicals that find their way into the air from these companies. Some of these chemicals are carcinogenic and affect humans, animals and plants. Examples of disorders that result from the chemical pollutions of the environment include respiratory disorders and cancerous growth.
Currently, there is an increasing concern about the level of environmental pollution. The primary concern is not about pesticides, but the increased amount of carbon dioxide in the environment. The use of pesticides in farms is decreasing because farmers are embracing environmentally friendly farming methods. The quantity of carbon dioxide that is in the environment has increased beyond the level in which nature can balance it. Most people believe that increased use of fossil fuels has led to such levels of carbon dioxide in the air. Its escalating level results in greenhouse gas effect that affects the climate negatively. The increased use of fossil fuels should be reduced and the environment given a considerable amount of time to balance the carbon dioxide.
