The 'Monthly Earth Day Phangan Node' project aligns with the EcoSynthesisX Spring Round themes of environmental and community impact. It aims to launch local initiatives that encourage global participation in environmental clean-ups, and it fosters community engagement and education on sustainable living practices. Its monthly cleanup initiative and its focus on reducing pollution directly tie into the Refi, DecSi, and global ecosystem themes specified for the EcoSynthesisX round.
