Earth Day started in 1970 with a humble beginning in the United States. Over the past 48 years, people have joined together to help sustain and protect the environment. In 2017, Earth Day took on a new meaning with international protests pushing for a more sustainable future. The Guardian reported: 'The main March for Science event was held in Washington DC, where organizers made plans for up to 150,000 people to flock to the national mall...' They also pointed out that over 600 protests were held across the globe. The March for Science event continues after the protest wrapped yesterday.
