Every year on April 22, over a billion people in 190 countries take action for Earth Day. From Cairo to Cape Town, Dakar to Djibouti, Africans plant trees, clean up their communities, contact their elected officials, and more — all for the environment.
Like Earth Days of the past, Earth Day 2014 will focus on the unique environmental challenges of our time. As the world’s population migrates to cities, and as the reality of a changing climate becomes increasingly clear, the need to create sustainable communities is more important than ever.
Earth Day 2014 focuses on promoting sustainable communities through its global theme: Green Cities. With smart investments in sustainable technology, forward-thinking public policy, and an educated and active public, cities can be transformed and a sustainable future achieved.
Nothing is more powerful than the collective action of a billion people.
As the global organizer behind Earth Day, Earth Day Network creates tools and resources for everyone to get involved with Earth Day in their communities. To find these resources, visit: http://www.earthday.org/greencities/resources/
