Rare observation: "I am an orangutan, which literally means people of the forest. I used to work in forestry. Going underwater was a total contrast. I was struck by the quiet. I wish we, as humans, would do more as we do underwater: observe and be quiet. Be more humble."


Rare’s courage to take risks makes me proud to work here. We are not afraid to take on ambitious efforts addressing big, intractable environmental challenges. That’s what conservation demands.”

Rare fact: The idea of the SDGs sprung from the need to get people to understand that actions, investments and policies are interconnected, that when the linkages are seized, sustainable development is not a zero-sum game. The challenge now is to overcome short-term thinking and understand that 2050-is-now: our actions and inaction today determine what the world will look like in the coming decades, centuries, millennia.


Having spent many years in the conservation world, I find that Rare fills a unique and important niche focused on people and human behavior to make lasting change happen benefitting both communities and the natural world.”
