Environmental activists display placards as they march towards the Chinese Embassy in Makati City, Metro Manila May 11, 2015. The activists demanded that Chinese authorities immediately put a stop to the ecological destruction caused by the reclamation activities of China in the South China Sea, which the Philippines calls West Philippine Sea. They also condemned what they say is the bullying by Chinese naval and coast guard forces of Filipino fishermen in the disputed seas, a environmental activist said. REUTERS/Romeo Ranoco
