Pollution threatens Caribbean
The Caribbean coast is being endangered by pollution, development and
overuse, according to a new environmental report. The capacity of Caribbean
countries to treat sewage has not kept up with the large numbers of tourists,
according to the report by the World Resources Institute group. Cruise
ships - a major component of the Caribbean's tourism market - were singled
out as being major polluters because they release sewage offshore. Mangrove
and coral reef areas have been contaminated by fertiliser from farms, and
the reefs have been further degraded by human contact and destructive fishing
practices. This could result in a drop in tourism revenues, because many
tourists travel to the Caribbean's coastal areas to explore pristine marine
environments, according to the report. The report noted similar problems
worldwide but argued that, because the Caribbean relies largely on tourism,
harm to coastal areas could have major economic effects. With the number
of visitors projected to rise, the group predicts additional environmental
pressures in the region.

Caribbean Sea under threat
The Caribbean Sea has been listed as one of the areas most seriously
damaged by human activity. A new study points to pollution from ships,
over-fishing - and climate change as the three major causes of damage to
marine ecosystems in the waters around the region. Scientists say nearly
every corner of the world's oceans have been damaged in some way by human
activity. The report recommends shifting shipping lines away from sensitive
areas. While subsistence fishing has a limited impact on ocean ecologies,
high-impact commercial fishing dumps millions of pounds of unwanted dead
fish, birds and mammals back into the ocean. This has threatened many species
of turtles, birds, whales, and dolphins with extinction. According to the
findings, shipping traffic is the third largest cause of damage. The fuel
gets spilled, there's noise pollution which is disturbing to whales and
such... which has a major affect on the ecosystem. It's recommended that
shifting shipping lines away from sensitive areas like coral reefs and
continental shelfs could significantly reduce the impact on ocean life.

Land Based Sources of Marine Pollution
The major sources of coastal and marine pollution originating from
the land vary from country to country. The nature and intensity of development
activities, the size of the human population, the state and type of industry
and agriculture are but a few of the factors contributing to each country’s
unique pollution problems. Pollution is discharged either directly into
to the sea, or enters the coastal waters through rivers and by atmospheric
deposition. Human activity in the area also accounts for a significant
amount of pollution, The Pan American Health Organization estimated in
1993 that only about 10% of the sewage from the Central American and Caribbean
Island countries is properly treated before being released into the Sea.

Marine pollution issues in the Caribbean
Marine pollution and coastal degradation have become serious development
issues in the Caribbean. Early evidence of marine pollution was mainly
anecdotal, but within the last 10-15 years, work conducted by universities
and research institutions in the Region has provided the beginnings of
a database that identifies several common marine pollution problems. The
United Nations Environment Programme (UNEP), the Intergovernmental Oceanographic
Commission (IOC) and the Pan American World Health Organization (PAHO/WHO)
have also been instrumental in co-ordinating several marine pollution studies.
In the English-speaking Caribbean, the University of the West Indies, the
Institute of Marine Affairs in Trinidad and Tobago, and the Caribbean Environmental
Health Institute located in St Lucia, have taken a lead role in identifying
marine pollution problems in their Sub-Region. For the Wider Caribbean
a database for petroleum pollution and marine debris has been developed.
Land-based sources of marine pollution have been identified as a major
problem, with several lsquohot spotsrsquo identified in mainland countries
and in some of the larger industrialised islands. Organic and nutrient
pollution, particularly from sewage, is most widespread and is possibly
the most serious marine pollution problem in the Caribbean. A lack of capital
investment funds to install the appropriate infrastructure to deal with
sewage and other liquid effluents is a major stumbling block to solving
the problem of marine pollution in the Caribbean. Other factors include
political will and administrative and legal structures to regulate human
development activities.

Plastic Pollution
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.

Birds are Dying
When researchers on Midway Island (near Hawaii) looked to see why juvenile
albatrosses were dying, autopsies found their stomachs filled with large
chunks of plastic. Tracking the adults' journeys led researchers to a “plastic
soup” in the Pacific gyre, created by a whirling vortex of currents that
pull in detritus from the Pacific Rim. The adult albatrosses were feeding
their chicks the colorful debris, mistaking lighters for squid. Estimated
to cover an area the size of Texas or larger, the “Great Pacific Garbage
Patch” is growing rapidly.

What sunscreen is doing
Scientific studies ascertained a relationship between sunscreen melting
off swimmers’ skins and the quickly increasing decline in corals. It turns
out that four common sunscreen ingredients (octinoxate, oxybenzone 4-methylbenzylidene
camphor, and the preservative butylparaben) activate dormant viruses in
corals, which go on to destroy algae - what corals feed on, and without
which corals turn white and die.
Anchors of motorboats, yachts, etc. – these can destroy corals and
thereby their entire ecosystem, which results in animals losing their homes.
Snorkeling and diving swimmers astonished by the reefs’ beauty touch the
fragile corals, causing serious damage.
