Every year on 22 April, people around the world mark Earth Day. One of its most popular causes has been planting trees, with organisers once setting the ambitious goal of planting one tree for every person on Earth.
It is easy to see why. Trees are quietly working for our health and our planet every day.
How trees help the planet
- They help fight climate change. Trees absorb carbon dioxide from the atmosphere and store it in their trunks, roots and leaves.
- They clean the air. Leaves and bark trap dust and absorb pollutant gases.
- They cool our cities. Shade from street trees can make footpaths and homes noticeably cooler in summer.
- They support communities. Trees provide food, habitat for wildlife and income for millions of people.
How trees help you
Spending time among trees is linked to lower stress, better mood and a greater sense of calm. The Japanese practice of shinrin-yoku, or forest bathing, is simply about slowing down in nature and noticing the sights, sounds and smells around you. Even a walk through a leafy local park can help.
Inspiring green records
Guinness World Records has celebrated some extraordinary feats for the planet over the years, including:
- Tubby the Labrador, a UK dog who helped recycle an estimated 26,000 plastic bottles collected on his daily walks.
- A record-breaking tree planting in the Philippines, where more than 120,000 people planted over two million trees in one hour across multiple locations.
- The largest tree hug, involving more than 1,000 people organised by the Korea Forest Service.
How to get involved
- Join National Tree Day, held each year on the last Sunday in July.
- Plant a native tree or shrub in your garden or on your balcony.
- Volunteer with a local Landcare or bushcare group.
- Donate to a reputable reforestation project.
- Make time to walk among trees each week, for your own wellbeing.
