For instance, some people like to take fish spears underwater to catch fish. This not only results in a reduction of that species, but also affects the local food chain, or it forces fish schools to swim farther out to sea. Try to avoid disturbing the ecology. Also, many divers trample on soft coral or move pieces of stony coral, so that the algae and other organisms living on them die.
例如有些人喜歡帶魚槍下海射魚，不只造成物種的減損，甚至影響當地食物鍊、或造成魚群遷往外地海域，這種足以改變生態的破壞行為應避免；也有不少潛水人踩壞珊瑚，或搬動礁石使附著其上的藻類和生物死亡，這些都是對自然界的災害，須特別注意。
