Since end of
seventies, the houses of middle class families gone for a huge makeover.
Slowly the age old wooden furniture vanished from their houses and smoothly it
was replaced by a lighter and colourful plastic made furniture. It can
be called a typical middle class mentality, it was cheap and it gave a fresh and
young looks to our houses.
So, welcome
to the world for plastic, we even don’t count that how many times a day do we
use something made from plastic, of-course unaccounted numbers of times. Surprising,
even last forty years plastic encroached to our houses but. plastic has been a
part of our lives for over 100 years, and its use continues to grow. You name
it, plastic chairs and tools, plates and glasses buckets, bottles and
mugs and of-course plastic carry bags.
Therefore, after we thoroughly invaded by the plastic and cannot imagine
life beyond it, we also realised how hazardous it is, is it too late?
All about
plastic
It is believed that
the first man-made plastic was created somewhere around 1862. It was an organic material that once heated could be molded. Plastics, materials made up of large, organic
(carbon-containing) molecules that can be formed into a variety of products.
The molecules that compose plastics are long carbon chains that give plastics
many of their useful properties. In general, materials that are made up of
long, chainlike molecules are called polymers. The process of making
plastic is a complicated one. It begins with carbon from petroleum,
natural gas, coal, or biological sources. The elements can
be combined in various combinations in order to achieve a desired property and
characteristic. The final product can be hard like the siding on your house or
soft and flexible like shrink wrap.
Due to their insolubility
in water and relative chemical inertness, pure plastics generally have low
toxicity. Some plastic products contain a variety of additives, some of which
can be toxic. For example, plasticizers like adipates and phthalates are often added to brittle plastics like
polyvinyl chloride to make them pliable enough for use in food packaging, toys,
and many other items.
Plastics are
durable and degrade very slowly; the chemical bonds that make plastic so
durable make it equally resistant to natural processes of degradation. Since
the 1950s, one billion tons of plastic have been discarded and may persist for
hundreds or even thousands of years. Perhaps the biggest environmental threat
from plastic comes from nurdles,
which are the raw material from which all plastics are made. They are
tiny pre-plastic pellets that kill large numbers of fish and birds that mistake
them for food.
Pros and Cons of
Plastic
Pros: It is Convenient, durable and can be used
for years. Lighter, cheaper and occupy less
spaces.
Cons: Plastic
is a synthetic material that is both, easy and inexpensive, to produce. Its
light weight, durability and versatility make it a preferred material for
packing and manufacturing. However, its uncontrolled use leads to more problems
than it solves. The most commonly known and accepted argument against plastic
is that it is non-biodegradable, because of which it pollutes the natural
environment and poses a risk to living organisms. But, while this is true,
plastics are also known to have a harmful effect on individual health. Difficult
to degrade, a single plastic bag can take 20 to 1,000 years
to degrade and remain toxic even after they break down. Only 1% of plastic bags
are recycled. Ten percent of the plastic produced every year worldwide winds up
in the ocean. 70% of which finds its way to the ocean floor, where it will
likely never degrade.
!!!What we call it, an Environmental hazard or
a must (mast) artifact.!!!
