Young Hawaiʻians are fighting climate change to protect their traditions. Navahine and Kaliko, plaintiffs in a landmark lawsuit, pushed Hawaiʻi to commit to cutting transportation emissions by 50% by 2030 and fully decarbonizing by 2045. Rising sea levels, drought, and wildfires threaten fishponds, taro farms, and cultural practices like hula. Their case sets a global precedent for youth-led climate litigation and sustainable transport.
