Meanwhile, mounting fears about smog, pesticides and water pollution swept the nation. By 1970, the percentage of citizens who cited cleaning up air and water as one of their top three political priorities rose to 53 percent, up from 17 percent five years earlier.
As a result of environmentally-related unrest, an estimated 20 million people took part in the first Earth Day, drawing attention from both the media and the federal government. After the big day, litter cleanup programs and environmental seminars sprang up across the nation, particularly at high schools, colleges, youth groups and religious institutions.
As environmental issues came closer to the forefront, public discourse about stewardship increased both on and off Capitol Hill.
Since 1970, Earth Day has grown into a global celebration. An estimated 1 billion people in 180 countries participated in Earth Day in 2010, with events ranging from park and beach cleanups in the U.S. to tree-plantings in Indonesia.
With the eco movement rapidly becoming part of the mainstream, a whopping 77 percent of Americans now say they worry about protecting the environment a great deal or a fair amount, according to a survey conducted by ecoAmerica.
Some data shows that Earth Day participation is down the U.S., but in many cases, Americans are simply participating in a different way. Web-based campaigns, such as EPA’s Earth Day photo projects and Earth Day Network’s A Billion Acts of Green, are steadily growing in popularity. On Earth Day 2010, an estimated 30 million people used social media to encourage green activities.
So, whether you attend a local festival, relax in the great outdoors or head online for some Earth Day tips, make sure to mark the occasion this year and keep the tradition alive!
