Establishing marine conservation areas in accordance with the national master plan on biodiversity preservation is one of the most effective ways to protect the marine environment, which is at an alarming rate of pollution.

According to Assoc. Prof. Dr. Nguyen Van Cu, former head of the  Vietnam Administration of Seas and Islands, Vietnam aims to have 41 more  marine conservation areas by 2020. 
He suggested completing a framework of sea management institutions in  order to exploit and use marine resources in a sustainable fashion. 
Prompt actions should be taken to prevent environmental pollution and  degradation at the lower reaches of rivers and coastal industrial parks  and clusters, Cu said. 
In a parallel effort, more attention should be paid to environmental  impacts of tourism, oil exploration and exploitation, mining,  aquaculture and marine facilities in 28 coastal cities and provinces  nationwide, he stressed. 
Scientists from the Institute of Marine Environment and Resources  cited the community-base maritime resources management model, which has  been rolled out in several provinces like Ninh Binh, Nam Dinh and Kien  Giang, saying it is effective and economical. 
Besides, by empowering locals, the model has encouraged the community  to share the responsibility with the State for managing and preserving  marine resources, they said. 
Other jobs include raising public awareness of relevant policies and  laws, and enhancing international cooperation in this regard, both  bilaterally and multilaterally, especially in maritime science and  technology, search and rescue, and personnel training, they noted. 
Such suggestions have been made amidst the overexploitation of marine  resources, pushing the maritime system, at the risk of serious  pollution. 
Dr. Du Van Toan from the Vietnam Administration of Seas and Islands,  said most of the pollutants are sourced from the mainland, including  waste water discharged by coastal cities, urban areas and industrial  parks, along with oil leaked from drilling rigs and ships. 
More than ten out of 100 rivers in Vietnam like the Cau, Day and Thi Vai are now seriously polluted. 
All of them run to the sea, bringing with them 880 cubic kilometres  of water, 270-300 million tonnes of alluvium and a large amount of  pollutants, according to the Ministry of Natural Resources and  Environment. 
Unplanned tourism and aquaculture, plus air pollution are also blamed for maritime environmental pollution. 
As a result, up to 90 percent of coral reefs in Vietnam now stand at  the edge of being destroyed. The pollution also threatens about 85 types  of sea creatures with 70 of them listed in Vietnam’s Red Book.
