Interesting topic!!!
Some day ago I discussed this topic with Chairman HF Cheung and brainstormed an idea of removing mangrove for recovering mudflat or gei wai habitat. HF Cheung said they have proposed similar idea few years ago but any action involving removal of mangrove was strongly objected by mangrove expert and also WWF staff (Please correct me if I am wrong).
So, I think the key point of this program/campaign is not educating public but to compromise with the experts about balancing the ecosystem of Inner Deep Bay mudflat and ecological value of mangrove.
