One of the most often nagged about “bad guys” in the
environmental battle is plastic bags. Plastic bags contamination is gigantic and
at the same time intensely personal environmental problem. We touch and see
plastic every day of our lives. With every visit to the grocery store we can
readily see our waste footprint grow. Plastic is found in essentially
everything these days. While most plastics are publicized as recyclable, the
reality is that they're “down-cycled.” A plastic milk pack can never be recycled into
another pack — it can be made into a lower-quality item like plastic planks,
which can’t be recycled.
Millions of plastic bags are given out to consumers by hypermarkets
and stores to carry their goods in. They are cheap, light, long-lasting, easy
to carry and in many cases, free. Most commonly used shopping bags are made up
of High Density Polyethylene (HDPE). After these bags are castoff, they often
end up in landfills or as litter. Plastics are considered as pollutants because
these are non-biodegradable & cannot be decomposed into environmentally
safe materials by the action of soil bacteria (aerobic or anaerobic digestion).
These are toxic and take roughly four hundred years to breakdown.
Although
Plastic bags are appear to be delicate and light, their negative environmental
effects are devastating. They may cause large amounts of pollution in every
step of life cycle.
Manufacturing of plastic bags subsidizes to air pollution and energy
consumption. It takes 1000 years for polyethylene bags to break down into
smaller compounds. They can have a detrimental
effect on marine animals and wildlife in addition to the aesthetic effects on
beaches, parks and trees. These are potentially one of the key reasons of death
to marine animals. Up to 100,000 marine animals die each year from eating
plastic bags which are mistaken for food. This results in obstruction of
animal’s intestines, choking & immobility and sometimes as
bio-magnification.
As a solution to these types of problem is to take
action by educating and increasing the public’s awareness to the damaging effects
that a plastic bag impose on our environment. Applying this would mean to get
consumers involved in reducing the number of plastic bags they use. Another
important elucidation would be using biodegradable jute bags that take up a
shorter time to degrade. Research should be made in to making
bio-degradable plastic bags so people could use these ones instead of
the non-biodegradable.
Usage of plastic bags is
very limited unlike their infinite damages. They are harmful to health, the
environment and wildlife. The solutions to put an end to the problems
associated with plastic bags are available, collaboration between governments,
shops and individuals is vital to take the necessary actions by reducing,
reusing and recycling plastic bags.
