What’s the Fuss Over Plastic?
By
Linda Mason Hunter
Look around you. We live in a sea of plastic. We carry
around personal water bottles made of plastic, feed our
babies from plastic bottles, wrap trash in plastic bags,
bring vegetables home in flimsy plastic sacks, and eat soup
from aluminum cans lined with plastic. It coats our
cookware, and is even in our medical devices. What is this
doing to our planet? What is this doing to our health? The
health of our children?
Here’s the
skinny: Scientists are discovering that, while plastic may
be terrifically versatile and amazingly economical, it’s not
doing us any favors.
Environmentally
speaking, plastics are forever. Made from oil and natural
gas, they take 1,000 years to decompose in a landfill, if at
all. They accumulate in ever greater amounts on land and in
water. The results can be overwhelming. In the North
Pacific, currents have swept together a floating island of
plastic twice the size of Texas composed of tires, toys, all
kinds of plastic waste. Rather than dispersing, it has
doubled in size in the last six years (according to National
Geographic’s Green Guide), trapping animals in lost plastic
nets and shopping bags. There’s a similar “dead zone” in the
Gulf of Mexico.
Making the
matter personal, plastics are harming our health in ways
scientists are just beginning to understand. Synthetic
chemicals making plastic soft and pliable are composed of
toxins that leach into food, beverages, and disperse into
the air when heated. Amounts detected in studies are at
levels that cause neurological and developmental damage in
laboratory animals, and mimic the hormone estrogen at low
levels in humans. Problems include genital defects,
behavioral changes, and abnormal development of mammary
glands. Changes to mammary glands are identical to those
observed in women at high risk for breast cancer.
The chemical
currently in the public eye is Bisphenol-A (BPA), banned in
the European Union and in the process of being banned in
Canada, but still present in a wide array of food-related
products in the U.S.A. The latest revelation (November 2008)
is that BPA is present in more kinds of plastic than
previously thought. It’s not just plastics with the #7
recycling code, but in plastics with recycling codes 1, 2,
and 4, as well. That means BPA is present not only in hard,
clear plastics (such as baby bottles), and the lining of
food cans, it’s also found in frozen food trays, microwave
soup containers, plastic food packaging, microwave popcorn
bags, to name a few.
Two additional
studies, published in Environmental Health Perspectives last
fall, found that BPA lingers in the body longer than
previously thought, and that newborn babies are more exposed
to BPA than had previously been thought. Blood urine tests
showed many infants had ten times the level of BPA in their
blood as did adults, and one child had 350 times the median
level found in adult blood. Scientists believe that young
bodies are not mature enough to process the chemical as
adults do, so it lingers longer, and is more likely to have
ill effects.
The United
States leads the world in number deaths from cancer. One in
two men and one in three women will receive a cancer
diagnosis at some point in their lives. I think we need to
start paying attention.
To avoid Bisphenol A, experts recommend following these
seven tips:
- Do not
microwave food or beverages in plastic.
-
Do not
microwave or heat plastic cling wraps.
-
Do not place
any kind of plastic in the dishwasher.
-
If using
hard polycarbonate plastics (water bottles, baby
bottles, sippy cups), do not use for warm or hot
liquids.
-
Use safe
alternatives, such as glass.
-
Avoid canned
foods when possible.
-
Look
for labels on products that say “BPA-free.”
This is
important and critical information. Please heed.
