All you have to do is to spend £40 or more, and Green People will plant a tree. The World Land Trust know what they are doing. Since they were founded, they have planted over 2.3 million trees worldwide. And they work with local conservation groups to help save land for wildlife; their current appeal is to save forest and a wildlife corridor in Colombia. You can find out more here.
Now, this is only available on 21 March 2020 - but Green People are doing this sustainability offer one Saturday a month in 2020. Sign up for their newsletter and you can discover more about them and their offers and how they work.
The 21st March is International Day of Forests, so that's even more reason to give your support to the World Land Trust!
Oh, by the way.... did I mention Green People have an Organic Children Hand Sanitiser? And a Manuka and Lemon Tea Tree Antibacterial Hand Wash???
Head to Green People's website anyway, and go shopping! I use their products myself and I just LOVE them!
