An opinion poll shows 80 per cent of residents want at least one-fifth of the city's marine areas designated as no-take zones. Reclamation, dumping and overfishing are the most damaging activities to the marine environment, they say. In the WWF Hong Kong poll, made by TNS, 932 people aged 15 to 65 were asked about marine conservation. WWF said the results showed strong public support for its Save Our Seas proposal, which aims to ban fishing in Port Shelter, Tolo Harbour and Channel and all marine parks, to reverse depletion of fisheries resources. The proposal only accounts for 9.8 per cent of the total sea area. The group wants to achieve 30 per cent coverage eventually. The only no-take zone at present is at Cape d'Aguilar, which is just 0.016 per cent of the city's waters. Although only 20 per cent of respondents knew how many marine parks the city has, a majority are willing to take a more drastic approach to designate no-take zones covering at least 20 per cent of waters. One-third even support coverage of at least 40 per cent. More than 90 per cent say the concept of no-take zones is reasonable. Overall, 77 per cent of respondents rate marine conservation as the second most challenging environmental problem facing the city, after air pollution (93 per cent). One-third say reclamation is the most damaging activity, followed by dumping at sea and overfishing. An overwhelming majority agree that more should be done to protect marine life, and about 74 per cent believe it is primarily the government's responsibility. WWF chief executive officer Eric Bohm said that unlike air pollution, there was a need to raise public awareness of marine conservation, an urgent issue that has been 'out of mind and out of sight'. 'The sense of degradation of the marine environment might only be felt when the fish price is too high.' WWF director of conservation Andy Cornish said the group was advocating a ban on destructive bottom trawling and also believed there should be adequate compensation and job retraining for fishermen affected by no-take zones.
