Environmental consciousness began to enter our lives in 1962 when Rachel Carson published
Silent Spring.
But if you search out online information, you will learn a lesson about the Internet. I entered the search terms "carson silent spring" and this was the response at 9:42 AM Pacific Time, from San Jose, CA, USA:
1. The amazon.com sponsored link to buy the book in hardcover, paperback, soft cover, and electronic form.
2. A link that has been up since 2012, offering to sell you the 50th anniversary edition of the book, by
http://www.rachelcarson.org.
3. The WikiPedia article on the book.

In order of popularity, in the first dozen hits we have:
1. Six offers to sell you the book. One of the six actually claims it will share revenue with the estate of Rachel Carson, the rest are pirates.
2. Three ".org" sites, two of which are indistinguishable from their ".com" brethren. Wikipedia is the other, claiming to be noncommercial, but including in the book article references over a dozen links to sites selling the book or related merchandise.
3. Two debunkers that are also selling their dissing of the book.
4. One biographer selling the Carson biography.
I read this book in the 1970s. You cannot understand the essence of what was said any other way than by reading it. Anything else short of that is you swallowing the book commentary by somebody else. I'd bet from the stuff I saw on those links that they were largely written by people who also never read the book itself.
Reality - what a concept. The stuff online is not reality, it is a virtual world whose real purpose is to sell things to you. If you ever for one moment forget this, you are deceiving yourself.
