Pacuare River Conservation History
Costa Rica Runs on >75% Hydropower
Protecting the Pacuare River
“I started trying to save a river and a rainforest valley that would have been ruined by being dammed. Nature would have been killed. But we did not comprehend then how far-reaching our activism would be. We ended up causing ICE to have to create environmental impact report policies. We pushed them to look into developing other alternative energies, which has led to wind, solar, and geothermal energy projects in Costa Rica, moving away from hydroelectric dams over the years.”
