After taking a close look at controversies surrounding
plastic, I understand that plastics are problematic. But to what extent? In Part
One of this series, I discovered that a mass of plastic and garbage has
formed in the Pacific Ocean and is affecting
marine life. Part
Two discussed controversial medical claims that plastic contains harmful
additives that migrate from food wrappings, containers, and toys. Although some
of these claims are disputed and unresolved, it still makes me wonder – what are we supposed to do?
As long as plastic's health effects remain debatable, our primary
concern should be what to with our plastic waste. Many people believe that the answer
to this garbage problem is to get more people to recycle. After reading your comments
from Part One, it's clear that some countries are implementing successful recycling
initiatives; however, where I live, recycling isn't a pressing issue. When I
asked my landlady for recycling bins, she looked confused and said that she
didn't know anything about them.
According to a 2005 statistic from the United States
Environmental Protection Agency (EPA), only 6% of the plastic made in the U.S. is
recycled. One way to get people to recycle more is to implement a "bottle bill" which would establish a minimum
refundable deposit on plastic water bottles. Such legislation has been proposed
in many places as a way to give people financial motivation to recycle their
plastic bottles. Although most soda bottles are refundable in certain states, plastic water
bottles are generally non-refundable and often thrown into the trash. But
as PWSlack said in a comment to Part One, "Throw it away? There is no 'away.'" (I love that quote).
According to BottleBill.org, "The so-called 'bottle bills'
were intended not only to reduce beverage container litter, but to conserve
natural resources through recycling and reduce the amount of solid waste going
to landfills. They proved to be extremely successful in achieving those goals."
But if only 6% of plastic made in the U.S. is recycled, how "successful"
have these bottle bills been?
Another option that was brought up numerous times in Part
Two's commentary was the idea of using glass bottles. Bringing glass bottles
back would have its pro's and con's, as was mentioned in the discussion. Glass
bottles are refillable, but they are also heavier than plastic and would
increase petroleum usage in shipping. I don't know about anyone else, but I
don't want to see gasoline prices skyrocket again.
Switching to glass or implementing bottle bills still may
not reduce waste and litter. In an attempt to solve this problem, researchers
are working on developing biodegradable plastics called bioplastics. These
materials derive from plants like hemp, soy beans, and corn starch and will
decompose in the environment. Environmentalists are wary of this emerging
industry because the machinery used to produce bioplastics still relies heavily
on petroleum usage. Currently, bioplastics would be an expensive alternative;
however, these plastics do not contain the toxins that have been associated
with health risks.
Even after completing all of the reading I've done on
plastics, I still don't know if - or what - I should change. I'm not convinced
that plastics are the only materials that contain potentially harmful
chemicals; until I know more about how metals and glasses are produced, I can't
really say that plastics are the worst choice. Still, it's always good to know
what controversies are out there and what both sides are saying.
What do you think is
the answer?
