Water was meant to be in rivers. Sure some is needed for irrigation, some for power, some for cities. But fish, birds, animals, even people, also need water in the rivers. Without it, endangered species like salmon will not survive, whole ecosystems will be destroyed and recreational opportunities will be lost. Support the removal of the Matilija dam in California with the YC Dam T-shirt. The organic cotton tee features artwork by Nathan Reifke.
This is the same dam that was featured in YC's American Express commercial and was recently tagged by dam removal advocates.
