Dear Friend,

First, let me express my heartfelt thanks for your past support of Koko, The Gorilla Foundation, and our mission of Conservation through Communication. Your generosity means the world to me!

For over 45 years, I had the extraordinary privilege of working with Koko — a gorilla who learned to communicate with us through sign language.

She didn’t just change my life — she changed how the world sees gorillas: as intelligent, emotional beings with a deep capacity for love, empathy, and connection.

Now, we have a chance to use Koko’s legacy to save all gorillas from extinction.

This Earth Day, I invite you to watch a short video of children in a remote village in southeast Cameroon using the Koko Signs app at the world’s first Koko Compassionate Conservation Camp. These children live on the outskirts of a forest inhabited by the critically endangered western lowland gorillas.

Your Earth Day gift will help us:

1) Deliver the Koko Signs app to more gorilla habitats across Africa — empowering children and adults to connect with gorillas as thinking, feeling beings.

2) Create a compassionate conservation curriculum — using Koko and Michael’s sign language stories to spark empathy and inspire local action.

3) Empower community-led protection for Cross River gorillas — the most endangered gorilla subspecies on Earth, with fewer than 300 remaining in the wild.

Koko showed us what’s possible when we give gorillas a voice.
Let’s honor her legacy — and protect all gorillas, before it’s too late.

or:

and receive a Koko Plush as a thank you gift.

Please join me this Earth Day — and help turn Koko’s vision for gorillas into reality.
