Who we are

a global coalition of lively, respected, and like-minded organizations and experts, determined to bend the curve
on
ecological overshoot - human numbers, appetites, and mindsets 
We don't always agree on everything - but advancing solutions together is more important than perfect agreement.
______________________________________________________________________________________________________ 

ALERT: We do not agree or associate with eco-nativist or anti-immigration groups. Human migration is happening: we'd best be prepared and positive.
