In 1970, the first Earth Day sparked a massive public response, with 20 million Americans taking to streets and college campuses to speak out against air and water pollution, wilderness loss, and animal extinctions. The public outcry led to the formation of the Environmental Protection Agency and legislation to safeguard air, water, and endangered species.
Although significant progress has been made in controlling pollution and preventing the extinction of notable species such as the bald eagle and California condor, the concerns of the past still linger. Furthermore, we now understand that human-caused climate change poses a significant threat that needs urgent attention to avoid extensive disruption of societies worldwide.
