Scientists said the whale died from gastric shock and starvation, according to media reports.
Blatchley called for government action "against those who continue to treat the waterways and ocean as a dumpster."
A young pilot whale was found in the waters off Thailand last June with a stomach full of plastic shopping bags and other plastic debris. Veterinarians were unable to save the starving whale.
Scientists also discovered 64 pounds of plastic garbage inside a young sperm whale that washed up on a beach in southern Spain in last February and believe the plastic trash also killed it.
Over the past 10 years, in the Philippines alone, scientists have recovered 61 dead whales and dolphins that have died from fishing nets, dynamite fishing and plastic garbage, CNN reported, and four were pregnant.
“This cannot continue. The Philippines needs to change from the children up or nothing will be left, Blatchley said.
A report from the Ocean Conservancy in 2017 found that that the majority of plastics pollution in the oceans originates from rivers in five Asian countries: Thailand, China, Indonesia Vietnam and the Philippines.
