2. Trash Hero Thailand
Thash Hero is an international community of volunteers (locals and tourists alike) who get together for weekly cleanups — and to hang out afterwards. Taking part in one of the Trash Hero events in Thailand (be it in Bangkok, Koh Chang, Koh Phangan or other locations around the country — you can subscribe to their Facebook page for updates) is a fantastic way to meet new people and make your contribution to the health of Thailand’s unique nature. No cost, no sign-up — just show up!
