The Philippines is an archipelago of over 7,000 islands located in Southeast Asia. It has a tropical maritime climate with three seasons and is bordered by seas to the east, west, and north. The islands have mountainous terrain covered primarily by tropical rainforests. Deforestation, air pollution from vehicles, and water pollution from trash are major environmental problems in the Philippines. Efforts to clean areas and promote recycling could help improve the environment. The country has a high level of endemic wildlife species, including over 100 unique mammal and bird species.
