The original Earth Day on April 22, 1970, billed as “The First National Environmental Teach-In,” came about with the mounting concern that the global environment was slowly being disassembled.

Rapid population growth, disappearance of plant and animal species, and air and water pollution were combining to bring mounting pressure on the environment.
