Marine pollution problem for China

BEIJING, June 20 (UPI) — Explosive economic growth in China’s coastal regions has led to levels of ocean pollution that threaten human and marine life, a government report concluded.

The State Oceanic Administration of China says 18,000 square miles of Chinese coastal oceanic territory is seriously polluted, an increase of 7,000 square miles from last year, Inter Press Service reported Monday.

As expanding coastal centers dispose of a growing amount of industrial and domestic waste at sea, about 56,000 square miles of the country’s coastal waters failed to meet standards for “clear water” in 2009, the SOA reported.

Overall, 14 of the 18 ecological zones monitored by the SOA were found to have unhealthy levels of pollution. SOA’s 2010 China Marine Environment Bulletin reported that 86 percent of China’s estuaries, bays, wetlands, coral reefs and seaweed beds were below what the agency considers “healthy.”

Government officials acknowledge much remains to be done in tackling the problem of ocean pollution.

“Our environmental quality is only improving in certain areas, but overall the environment is still deteriorating,” Vice Minister of Environmental Protection Zhang Lijun said.

Coral spreading northward in Japan as ocean temperatures rise

Corals that inhabit warm ocean areas are spreading northward in Japan’s coastal waters, apparently due to global warming, researchers have announced.

According to a research team from the National Institute for Environmental Studies in Ibaraki Prefecture and the Kushimoto Marine Park Center in Wakayama Prefecture, the northern limits of the habitats of several species of coral lying mostly near the Nansei Islands south of Kyushu have been moving northward at a “unprecedented speed” of up to 14 kilometers per year.

The unusual phenomenon is thought to have been caused by rising sea temperatures associated with global warming. As corals serve as the home for various marine plants and animals, researchers fear a possible change in the regional ecosystem.

In the sea around Japan, average water temperatures in winter have risen by 1.1 to 1.6 degrees Celsius over the past century. Out of nine species of corals that the research team analyzed, four that live in tropical waters have so far spread northward. One of the four species was observed inhabiting the area near Kagoshima Prefecture’s Tanegashima island in 1988, but was found to have spread 280 kilometers northward to Nagasaki Prefecture’s Goto Islands 20 years later.
