Environment officials blamed climate change and global warming for the marked decrease in the number of waterbirds feeding on Lake Buluan, the marshland and inland waters of Sultan Kudarat. Dr. Sabdullah Abubacar, regional executive director of the Department of Environment and Natural Resources (DENR) in the Soccsksargen region, said climate change had killed some bushes and other species that the birds must have been feeding on, prompting some of them to look somewhere else for food. Abubacar said this to explain why the number of waterbirds monitored by environment personnel this year decreased by 46 percent or 8,900 of the 16,500 birds monitored last year.
