There is no Planet B. We all live on the same planet, and it's in crisis. Many scientists consider that we are at a tipping point.

One Tree Planted is a reforestation charity. It's a non-profit organisation focused on global reforestation. It's on a mission to make it simple for anyone to help the environment by planting trees. Projects span North America, South America, Asia, Africa and Europe. It planted 51,967,225 trees in 2023.

The Doctor is In provides profile writing, strategic guidance and LinkedIn surgeries focused on LinkedIn, the world's most important business platform, with over a billion members.

The Doctor is In is now a Tree Ambassador for One Tree Planted.

I donate a percentage of fees earned for all the Doctor's services to One Tree Planted.
