Rachel Carson's "Silent Spring" is just defined in one word: Revolutionary.
The author take us beyond our trashy city-park, beyond our polluted city, she takes us to explore the world being attacked by the human kind.
"Silent Spring" was published a couple of decades ago, but we can see that what this book said was true and what Rachel Carson predicted is yet becoming our reality.
The book is very interesting and we may appreciate that the author made a huge research in this topic, basically DDT spraying and treatment.
The book emphasizes on the problems pesticides cause, not only to humans but to nature itself. The author tries to change people thoughts, and make us aware of the danger this chemicals being poured into our fields represent.
The book also gives alternatives to common pesticides and investigates each case of alternatives that is, or was, used.
As we know, Rachel Carson wrote this book long ago, making it now old, or out of date, but as you read it you realize that "Silent Spring" is clearly showing our modern date ecological problems.
So, with all this, I think Rachel Carson's "Silent Spring" is a magnificent book, a bit polluted in the way is written, but a magnificent work.
