Going green. Giving back to land on National Tree Day
Today we’re calling everybody with a green thumb for none other than National Tree Day. Originally co-founded in 1996 by Planet Ark and Aussie superstar Oliva Newtown-John, the annual event is a call to action for all Australians to give back to our planet and plant one million new native trees and shrubs across the country. Around 300,000 people volunteer their time each year, not just to get their hands dirty, but to help educate others about the world we inhabit.The tree you’re seeing in today’s image, by the way, is a Eucalyptus diversicolor - more commonly known as a karri. Karris are common around the wetter, southern regions of Western Australia and are one of the country's tallest specimens. Some, in fact, are said to reach up to a whopping 90 metres in height!
