Yesterday marked the world’s 44th Earth Day. At its heart, Earth Day aims to raise awareness and encourage consciousness about the environmental movement. Today, over 1 billion people celebrate Earth Day. Growing from a national rally of 20 million Americans, Earth Day has become the largest secular international holiday.
This year, the Earth Day Network (EDN) promoted the international holiday under a “Green Cities” campaign: the goal was to decrease climate change emissions while encouraging the growth of “green” urban practices. The EDN is simultaneously aware that while cities emit a large percentage of the emissions that increase global warning, they are also a huge source for potential sustainability projects such as urban gardening, solar energy intake, education, and more.
