As our oceans and coastlines face increasing threats from pollution, initiatives like International Coastal Cleanup Day become more crucial than ever. This global event brings together communities, volunteers, and organisations to tackle the growing problem of marine debris. In Malaysia, Reef Check Malaysia has been at the forefront of these efforts, playing a pivotal role in mobilising local participation and raising awareness. We speak to Julian Hyde, the CEO of Reef Check Malaysia, and Theresa Ng, Reef Check Malaysia's Chief Operations Officer,  to explore the impact of International Coastal Cleanup Day in Malaysia, the challenges faced, and the inspiring stories that drive this important work.
