Step-by-step explanation:
The Edge of the Sea, written by Rachel Carson, is a naturalist book that describes the coastal environment and its inhabitants. The central idea of the book is to explore the interconnection and interdependence of the life forms that inhabit the sea and the shoreline, and how they are affected by the changing tides and seasons.
Carson emphasizes the importance of understanding the delicate balance of the coastal ecosystem, and how human actions can have a negative impact on it. She highlights the diversity of life forms present in the coastal environment, from microscopic plankton to large mammals, and how they all play important roles in the ecosystem.
Throughout the book, Carson also explores the relationship between the sea and human society, and how the sea has shaped human history and culture. She also reflects on the human impact on the sea, and how pollution and industrialization have threatened its inhabitants and altered the delicate balance of the ecosystem.
The central idea of the book is to raise awareness of the importance of the coastal environment, and the need to understand and protect it. Carson's message is that the sea and its inhabitants are not only an important part of the natural world but also of human culture, and that human actions have a profound impact on the sea and its inhabitants. The book is a call to action for the readers to be mindful of their actions and take steps to protect the coastal ecosystem.
