Ocean Garbage Patch: Causes, Effects and Solution
What
is Ocean Garbage Patch?
It
is a large system of ocean surface current moving in a circular fashion driven
by winds movement of marine debris particles. These collections of plastic and
other debris, waste are not compact, most of it is near the surface of the
ocean and it can be found up to more than 30 metres deep in the water (ocean).
Garbage patch grow because of widespread loss of plastic from trash collection
system. Patches contains micro-plastics, plastic pellet, goods appliances lost
from shipping, flood etc.
What are the sources of
Garbage Patch?
· Tons
of plastic wastes moves from roads areas into storm drains during heavy rain
and wind in coastal cities which washes into the Ocean. These storm drains and
rivers act like a well design conveyor belt system for the movement of tons of
trash from cities area to coast every-year during rainy days.
· Near
the coastal areas people leave plastic bags, bottles, trash cans on the sand
where winds and tides pull them away to the sea.
· Cargo
ships and Ocean Liners throw waste overboard. Sometime storms knock off the
container from a cargo ship.
· Fishing
activities are one of the main causes of garbage patch in ocean. Fishing
industries consists of huge ships along-with huge ropes, traps which abandon
them in the ocean. These things are made up non corrosive material. It floats
and moves along-with the ocean current.
Impact of Garbage Patch
Ø On
Ocean Life
· Aquatic
animals like turtles, fish and sea birds by mistake eat away these brightly
coloured plastic as food which negatively affect on their digestive system.
· Whales,
Sharks etc get traps on the abandon nets. Injuring and drowning them.
· Plastic
release chemical Toxins into the ocean water and leach chemical additives into
marine organisms when eaten.
Ø On
Ecosystem
· Plastics
on the ocean surface when exposed to sunlight slowly degrade and release
methane and ethylene into the atmosphere which are Greenhouse gases.
· Marine
organism get interfere with micro-plastics reduces the oceans capacity to
absorb carbon dioxide.
· Floating debris acts as carrying non-native and invasive coastal organism into open ocean habitats where they disrupt natural balances.
Five Major Ocean
Garbage patch
1.Great pacific garbage patch: It is the largest garbage patch of all. Located in between Hawaii and California in North Pacific
2. South pacific garbage patch: Located off the Western Coast of South America.
3. North Atlantic garbage patch:
Located between North America and Africa.
4.South Atlantic garbage patch:
Located between South America and South Africa.
5. Indian Ocean garbage patch:
Located in the waters of the Indian Ocean east of South Africa.
Why Patch Clean-Up is
so hard?
· The
rate of removal of trash by the ships is slow than that of arrival of new trash
i.e plastic waste continuously flows from the river to the ocean.
· Micro-plastic
are scattered over a large area make it impossible to scoop up all at a once.
· The garbage collecting nets or tools can harm
ocean organism lives right at the surface.
· These
garbage patches are located at remote region which requires huge ship and
funding.
How can clean or
prevent Garbage patch
A
simple and more effective solution is that prevent new waste from entering the
ocean and active the offshore cleaning up.
· River
barriers and interceptors should be installed to scoop out debris from
polluting rivers before opening into the ocean.
· Implementing
strict Government policy and regulation for the improvement of waste management
structure.
· By
choosing reusable bags, bottles, cups etc
· Recovering
abandon commercial wastes from the cargo ships and fishing coumminity.
Few
major Organization working for clean up Oceanic garbage patches
1. The Ocean Cleanup
2. 4ocean
3. Ocean Conservancy
4. The Great Bubble Barrier
The
ocean garbage patch is a serious environmental problem cause mainly by the accumulation
of plastic and other waste in ocean current. Its harms marine animals, damages
ecosystem, and can eventually effects human and coastal communities. Although
the garbage patches are difficult to clean completely, we can reduce the
problem by using less plastic, recycling properly, preventing waste from
entering rivers and oceans, and supporting effective waste management system.
Protecting our ocean is everyone’s responsibility, and preventing pollution is
the most effective way to keep the ocean clean for future generations.
