In San Andres, a fishing village on Isla Verde, children play on the remains of the houses that were destroyed by Typhoon Nina in 2015, along with many of the village's fishing boats. A young woman named Gela Petines, a dive tour operator and advocate for the fisherfolk of San Andres, crowdsourced using Facebook to raise 500,000 Php to provide 25 boats to the families that had lost theirs in the storm. San Andres has built a sea wall since, which stands behind the young girl and faces out towards the Verde Island Passage, a body of water believed to be the center of the center of marine biodiversity in the world; marine scientists only recently discovered that the Philippine seas are home to more species of marine life, including corals, than anywhere else on Earth. However many argue that sea walls create a false sense of security, being ineffective defences against climate-change-related disasters, including rising sea levels, intensifying and increasingly unpredictable typhoons, and storm surges.
