Today, environmental problems in the Philippines include pollution, mining and logging, deforestation, threats to environmental activists, dynamite fishing, landslides, coastal erosion, biodiversity loss, extinction, global warming and climate change.[1][2][3] Due to the paucity of extant documents, a complete history of land use in the archipelago remains unwritten. However, relevant data shows destructive land use increased significantly in the eighteenth century when Spanish colonialism enhanced its extraction of the archipelago's resources for the early modern global market.[4] The Philippines is projected to be one of the most vulnerable countries to the impacts of climate change,[5] which would exacerbate weather extremes. As the Philippines lies on the Pacific Ring of Fire, it is prone to natural disasters, like earthquakes, typhoons, and volcanic eruptions.[6][7] In 2021, the Philippines ranked the fourth most affected country from "weather-related loss events", partly due to the close proximity of major infrastructure and residential areas to the coast and unreliable government support.[8][9][10] One of the most devastating typhoons to hit the archipelago was Typhoon Haiyan, known locally as Yolanda, in 2013 that killed 6,300 people and left 28,689 injured.[11] Congress passed the Clean Air Act of 1999, the Philippine Clean Water Act of 2004, the Climate Change Act of 2009 to address environmental issues. The country is also a signatory to the Paris Agreement. However, research has found that outside of cities, the general public doesn't feel equally informed.[12][8] Environmental activists and land defenders, consisting mostly of Indigenous communities who have been attempting to bring attention to the environmental issues in the country have been met with violence or murder. As a result, the Philippines has been ranked one of the most dangerous places in the world for environmental activists. It also has one of the highest percentages of climate change denialists in the world.[13][2]
