Ocean Gyres & Garbage Patches
Plastic is not absorbed by the ocean. Plastic which ends up there
is fragmented into smaller and smaller bits. These bits never go
away, but get caught up into ocean gyres, causing devastating impact
on wildlife.
A "gyre" is a slow moving ocean current which forms into
a massive whirlpool. There are five enormous ocean gyres which fill
our oceans today, as well as smaller gyres across all our oceans.
The sizes of these gyres fluctuate. The Great Pacific Garbage Patch
ranges from the size of Texas to and area larger than the continental
United States. The fragmented plastic which gets caught up in the
gyres becomes a soup of tiny plastic pieces which pollute our oceans.
It is hard to quantify the size of the garbage patches, because
while the center of the gyres can have up to 40 times the amount
of plastic than it does plankton, much of the surface area is thinly
spread over vast distances.
As ocean wildlife try to forage for food in the soup of plastic
bits which make up the ocean gyres, they end up eating a lot of
plastic. Their stomachs cannot digest the plastic, yet they feel
like they have eaten a full meal. Since they are not able to absorb
nourishment from plastic, they starve to death. As the plastic moves
through their digestive track, it often blocks their system, which
can also kill them. The United Nations Environmental Programme estimates
that over one million seabirds and 100,000 whales, seals,
fish and turtles die by ingesting plastic every year. Plastic
bags, in particular, are confused with squid by whales, and thought
to be jellyfish by sea turtles.
How does this problem impact us directly? Persistant
Organic Pollutants (POPs) are toxins like PCBs, DDT and other chemicals
used in pesticides. Plastic waste has been found to absorb these
POPs as they are washed through our watersheds. They carry the pollution
to the ocean, adding a large dose of toxic chemicals to the already
deadly plastic soup gathered in the ocean gyres. Scientists are
beginning to question whether these toxins are working their way
up through the food chain, becoming more concentrated in the animals
as they near the top of the chain...making it very dangerous for
those at the top of the food chain (read: humans)
There is no known way to clean up these enormous patches of plastic
pollution. One reason it is so difficult is that we don't know a
way to remove the "soup" of small plastic bits without
removing the plankton which is floating there as well. Why
is plankton important? It is the base of our food chain. It produces
half of the oxygen we breathe, as well as capturing half the carbon
in the atmosphere. There are areas in the ocean gyres which
have 40 times the amount of plastic as it does plankton. The more
plastic fills our world, the less room there is for other forms
of life. Biodiversity increases the chance of survival for all organisms,
including humans.
Our best bet in confronting this problem is to stop it
at its source. As individuals, we have the power to make
choices that will have a direct impact this enormous problem. If
we choose to cut down or avoid single use plastics in our day to
day lives, we can have a profound influence on building a solution.
Ultimately, my paintings about plastic will be used as an educational
tool with the aim of reducing our consumption of single use plastics.
