Corregidor's south dock, especially Lorcha, is awash with trash. Nope, it's not from the island's inhabitants. Rather, the trash comes all the way from Manila Bay, Navotas, Malabon, Cavite and Mariveles. Most are plastic packaging (read: non-biodegradable).S o please refrain from throwing your trash into the bay. And please quit thinking "it's only a piece of wrapper". Not only is the scene unsightly, the volume of trash impacts on the environment as well.
