Threats to the Marine Environment
Many cultures have treated bodies of water as convenient
repositories for trash, "bottomless" sources of food and natural
resources, or something to be dredged, filled, or drained when deemed
necessary. Although we know better in these environmentally-aware times,
misuse continues around the world, while areas with improving attitudes and
practices will remain scarred for years to come. Here are a few examples
human-induced impacts upon coral reefs observed around the Pacific. |

Marine debris, mainly plastic, accumulates as drift lines
in the open ocean, bays and harbors, and beaches. This is a common sight
in Hanauma Bay at the 'Witches' Brew', where winds and waves accumulate trash
against the sea cliffs. |
The beaches and reefs of the Northwest Hawaiian Islands
receive the lion's share of marine debris due to prevailing winds and currents
in the North Pacific. Employees of various government agencies and
volunteers remove hundreds of tons of discarded fishing gear (nets, rope and
fishing line) from coral reefs, in addition to every conceivable type of trash
off these formerly pristine islands inhabited by the endangered Hawaiian
Monk Seal and Green Sea Turtle. |
The pre-industrialized world disposed of trash easily since
natural products were biodegradable. The rapid spread of a
westernized lifestyle to traditional cultures has many drawbacks including
waste-disposal. For example, banana leaves and gourds used with meals were
easily discarded. The plastic and aluminum replacements are still
discarded in the same manner. |
