How did the book Silent Spring change American History?

With the kinds of environmental abuses and neglect that
was taking place in the 1950s and 60s, it was inevitable that a green movement of some
sort would start, just as in the 1850s, it was inevitable that an abolition movement
would grow.  In that time period, the book Uncle Tom's Cabin sold
hundreds of thousands of copies and changed minds, increasing the size and momentum of
the anti-slavery movement.

Silent
Springdid something similar.  It took a fledgling movement and an unknown
debate topic and brought it into specific relief.  It made it into a national
discussion, and there were magazine and journal and scientific and political responses
to it.

Did it change history?  Yes it did.  Just not all by
itself.  The car was already running, her book just stepped on the
gas.
