7 environmental stories that are giving us hope this Earth Day

[Social Media]

Every year more than a billion people mark Earth Day by taking action to protect the planet.

 

Earth Day 2023 is just a few weeks away, on Sunday 22 April.

It was first celebrated in 1970 when a US senator from the state of Wisconsin organised a rally to raise awareness of environmental issues. Thousands of people took part in demonstrations across the country and by the end of the year, the US government had created the Environmental Protection Agency.

 

Now it is celebrated in more than 190 different countries with people taking part in events organised by EARTHDAY.ORG. This year’s theme is Invest in Our Planet which includes a call to “act (boldly), innovate (broadly) and implement (equitably)”.
