‘It only takes one person to bring down a dam.’

“When dams were erected on the Columbia, salmon battered themselves against the concrete, trying to return home. I expect no less from us. We too must hurl ourselves against and through the literal and metaphorical concrete that contains and constrains us, that keeps us from talking about what is most important to us, that keeps us from living the way our bones know we can, that bars us from our home. It only takes one person to bring down a dam.” 
― Derrick Jensen, A Language Older Than Words
