- endangered marine species include the dugong, sea lion, sea otter, seals, turtles, and whales;
- oil pollution in Philippine Sea and South China Sea;
- dotted with low coral islands and rugged volcanic islands in the southwestern Pacific Ocean;
- subject to tropical cyclones (typhoons) in southeast and east Asia from May to December (most frequent from July to October);
- tropical cyclones (hurricanes) may form south of Mexico and strike Central America and Mexico from June to October (most common in August and September);
- southern shipping lanes subject to icebergs from Antarctica;
- occasional El Nino phenomenon occurs off the coast of Peru when the trade winds slacken and the warm Equatorial Countercurrent moves south, which kills the plankton that is the primary food source for anchovies;
- consequently, the anchovies move to better feeding grounds, causing resident marine birds to starve by the thousands because of their lost food source
