Public awareness and concern
the environment and public health
took a giant step forward

"Silent Spring" was published in
After the 1969 Santa Barbara oil spill,
a U.S. Senator from Wisconsin,
decided to try to channel
energy of the anti-war protest movement

He then announced his idea for
"a national teach-in on the environment" to the media.
As a result, on April 22, 1970,
20 million Americans demonstrated across the nation
for a healthy environment and Earth Day was born.
