Saturday, on Earth Day, scientists across the globe took to the streets for the ‘March For Science’.
Earth Day is an annual event celebrated on April 22, and every year various events are held across the globe to demonstrate support for environmental protection.
It was first celebrated way back in 1970, and now Earth Day events take place in more than 193 countries across the globe.
