Biodiversity is Health

Breathing in a forest can strengthen your immune system.

Even just 90 seconds taking in the scent of certain trees — especially cypress — can increase natural killer cells in your body, aka the cells we need to help fight off viruses and even cancer. And the effects last. Spend a few hours in a forest and those effects can stick around for days.

This is nature as preventative medicine — strengthening our defenses before we ever get sick.

We believe forests belong at the heart of public health.

That’s why we’re planting them in cities around the world.
