Why It Matters
A study in the journal Science highlighted the success of a five-year fishing ban on China's Yangtze River, leading to a rebound in fish biomass and the recovery of the finless porpoise. This conservation success offers a potential model for Hong Kong, which is facing environmental challenges at popular tourist sites like Sharp Island.
What Hong Kong can learn from the Yangtze’s conservation success
The Yangtze’s turnaround was made possible by the political will to resist economic pressure. Hong Kong should implement similar principles

In February, a landmark study in the journal Science delivered rare good news for conservation: a five-year fishing ban in the Yangtze River had halted seven decades of biodiversity near-collapse. Fish biomass has surged, and the critically endangered finless porpoise has begun to rebound. Researchers showed that sustained, collective action can revive an ecosystem. The lesson for Hong Kong is both inspiring and urgent.
Hong Kong is at a critical juncture in its environmental history. Last October, more than 4,000 visitors flocked to Sharp Island in just one day. Some visitors dug up coastal organisms, trampled on coral beds and lit illegal fires. Although part of Hong Kong’s Unesco Global Geopark, Sharp Island falls outside the boundaries of any statutory marine park, leaving it without enforceable conservation protection.
Greenpeace sounded the alarm. The authorities responded, after the damage had occurred.
Hong Kong’s overnight visitor spending fell from HK$193 billion in 2015 to HK$128 billion (US$16.34 billion) last year, and ecotourism is seen as a pathway to growth. The government aims to double down on ecotourism with its Development Blueprint for Hong Kong’s Tourism Industry 2.0, but any success in meeting the challenge has yet to be seen.
Ecotourism is defined globally by clear principles agreed upon by organisations such as the United Nations, International Union for Conservation of Nature and Global Sustainable Tourism Council: it should minimise environmental impact, achieve genuine conservation outcomes and benefit local communities.
Unfortunately, much of what Hong Kong identifies as “ecotourism” falls short, resembling instead nature-adjacent mass tourism characterised by high foot traffic. Popular sites like Sharp Island, High Island Reservoir East Dam, MacLehose Trail and Ham Tin Wan are experiencing increased ecological damage.
Open Questions
- What specific policies will Hong Kong implement to enforce conservation at sites like Sharp Island?
- How will Hong Kong balance ecotourism development with genuine conservation outcomes?
- What are the specific economic benefits expected from successful ecotourism in Hong Kong?
- Will the authorities respond proactively to environmental damage in the future, rather than after the fact?
