Climate change threatens globe's most diverse marine ecosystem

Scientists at a conference in Batangas City, Philippines, have heard the world's most diverse marine ecosystem is in danger from climate change and needs immediate protection.

Attendees of the meeting, organised by Conservation International, were told by marine experts that the Verde Island Passage, a narrow region of seawater off the Philippines considered the world's most diverse, is threatened by a number of human-induced factors -- including global warming.

"The marine habitats and species of the Verde Island Passage are already threatened by human impacts, like overfishing, pollution and coastal infrastructure development," said Dr. Giuseppe Di Carlo, Conservation International's marine climate change manager.

"Climate change is intensifying these impacts, with severe consequences for the well-being of the people of the area, since they depend on fishing and tourism industry," continued Dr. Di Carlo, as quoted in an August 10 Environment News Service report.

The marine scientists said rising sea temperatures due to climate change are causing coral bleaching, which means corals no longer have the capacity to support the vast array of plants and sea animals that live on them.

"This workshop tried to offer concrete solutions to adapting to the effects of climate change, so that the unique biodiversity of this place can survive for future generations," added Dr. Di Carlo.

Suggestions for protective action for the passage included placing seagrass beds, mangroves and other habitats within protected areas; promoting alternative, less intrusive forms of income-generating activities for residents, and methods to reduce sediments capable of damaging corals.
