Teng Hoi is a non-governmental organization founded in 2003 that develops a number of programs linked to the environment and education to encourage participation and interest while providing measurable results. ‘Teng Hoi’ is a Cantonese phrase that translates as ‘listen to the sea’, a name that originated from our first program in the early 2000s – the development of a device to locate explosions underwater generated by illegal fish bombs. The sea provides feedback to us about the way our society lives. We believe that what we hear should be harmonious, but all too often it is not and explosions underwater are an extreme example of how our human society shatters the harmony. At Teng Hoi, we wish to restore that harmony. Our name serves as an ongoing reminder to listen attentively to the voice of the environment and prioritize its well being.
