The problems about plastics

Plastics are everywhere in our life. For more than 50 years the
global production and consumption of plastics have continued to
rise. Today we produce about 300 millions of tons every year.
The growing production replaces materials like glass, metal and
wood. About 4 percent of the oil production worldwide is used to
make plastic each year, and another 4 percent is used to power
plastic manufacturing processes with energy.
Plastics are derived from materials found in nature, such as
natural gas, oil, coal, minerals and plants. Because of their
intermolecular bonds plastics degrade very slowly in the nature.
They are also mixed with additives to improve their performance
like hazardous chemicals benzene and vinyl chloride or additives
like carbon or silica.
Our current usage of plastic is simply not sustainable. The
biggest amount of plastic, more than one third, is used for
non-durable plastic items like shopping or trash bags, plastic
bottles and other utensils. We are throwing them away after a
short time of usage.
If plastic gets recycled we still need new plastic as supplement
to produce the same product because when plastic is being
reprocessed, it changes to a lower quality. This means even if
no more plastic was needed only the same amount, nonrenewable
resources would still have to be used to produce the same
product. Recycling of plastic does not mean sustainable
recycling.
If they are discarded improperly they are ending in the nature,
sometimes for thousands of years. According a scientific working
group at UC Santa Barbara’s National Center for Ecological
Analysis and Synthesis 8 million tons of plastics are ending
alone in the ocean per year. They can be eaten by fishes and sea
animals. These often die from the physical and chemical impact
of these chemicals. Animals who survive can be a part of our
food chain and the plastics in their organism can have harmful
effect on the human body.
