This project grew out of an experience my friend and I had volunteering at the bay. We were taking part in a beach cleanup, and the single most common item among the litter we picked up was cigarette butts. That led us to bring together high schools across Shenzhen to launch this beach cleanup and a campaign for smoke-free beaches, in the hope that reducing the harm cigarette butts do to our beaches would help preserve the appearance of the city and protect the ocean.
