Cork river discussion, litter picks and new documentaries: Five ways to celebrate Earth Day

From litter kits and seed discounts to new documentaries, there are plenty of ways to mark the event from home

Earth Day's virtual events will take place on www.earthday.org later today.

On April 22 1970, around 20 million people took to the streets in the US to celebrate the first Earth Day, in what is still the largest turnout for a single-day protest in history. The collective call for action led to substantial environmental reform in the White House a year later.

Since then, over one billion people have been mobilised by the initiative, which has organising bodies present in 192 countries around the world.
