The rapid expansion of coastal megacities continues to pose a significant threat to marine ecosystems. A recent study highlights the concerning impact of vessel traffic on marine life in China's Greater Bay Area, home to 86 million people. The area's waters are increasingly at risk due to the surge in vessel activity.
Nearly 6,000 vessels operate daily in the Greater Bay Area, exposing marine species to constant disturbance. The Environmental Sustainability and Resilience Joint Centre (ENSURE) study revealed that this relentless vessel presence leads to several ecological issues. Propellers churn sediment, increasing turbidity and eroding shorelines. Noise pollution disrupts marine communication, and collisions pose direct threats to wildlife.
Conservation zones are under immense pressure, with some hotspots experiencing disturbances on 95% of days. Researchers are advocating for strategies such as rerouting shipping lanes, reducing vessel speeds, and utilizing quieter, less polluting ships to mitigate these impacts. These measures aim to protect vulnerable species and promote sustainable maritime practices in the region.
