In past centuries on beaches everywhere, including those encircling the Hawaiian
islands, beachcombing could be a profitable business, offering a potential treasure
chest of material washed ashore from ships sailing the vast oceans. Today what is
washed up on most beaches is far less appealing or rewarding and is only a small part
of the massive amount of pollution that is dumped or flushed into the sea every year.
The world’s largest marine reserve sits next to one of the world’s largest floating
garbage dumps. Between Hawaii and the United States mainland is the North Pacific
Gyre, the epicenter of a giant circulating system of winds and currents encompassing
the whole North Pacific. Plastic pollution from Asia, the Pacific and North America is
sucked into this area, where it mingles with sea life, choking and ensnaring marine
wildlife, and disturbing every level of the food chain.
Estimated to be the size of Texas, this phenomenon provides a stark reminder of the
threat that plastic poses to marine life. Because it doesn’t break down, such pollution
can linger for years affecting marine environments far from where it entered the
ocean.
