While
Earth suffers 'death by a thousand cuts,' ban highlights much-needed
environmental considerations

In
a move described as a "micro-sized miracle," President Barack Obama
on Monday signedinto law a bill banning the manufacture
of beauty products containing miniscule plastic particles, known as microbeads.
Environmental
groups have long-sought such a ban and heralded the move as an "important
step toward addressing the global crisis of microplastic pollution."
"Our
oceans are inundated with microplastics that threaten sea birds, turtles and
other marine wildlife. Now we can stop adding to the trillions of pieces already
out there," said Blake Kopcho, oceans campaigner with the Center for
Biological Diversity.
"This
will eliminate a pointless and harmful source of plastic pollution before it
ever has a chance to reach the oceans," Kopcho added.
The Microbead-Free Waters Act, passed by Congress, phases out the manufacture of face wash, toothpaste, and shampoo
containing plastic microbeads by July 1, 2017 and the sale of such beauty
products by July 1, 2018.
Scientists estimate that the ocean contains 5.25 trillion pieces of plastic debris. While just 269,000 tons of that floats on the surface, roughly four billion plastic microfibers per square kilometer clutter underwater ecosystems.
Given
those numbers, Steven Cohen, executive director of Columbia University's Earth
Institute, on Monday noted that "microbeads are only a small part of the
much larger problem of marine debris."
However,
Cohen says that the ban is a step towards addressing the larger issue of
manufacturers introducing products to market (such as face washes with
supposedly biodegradable plastic "scrubbers") without testing their
impact on the environment.
He
continues:
While
policy attention is focused on large, world-scale issues such as climate
change, the planet continues to die the death of a thousand cuts. We ignore the
day-to-day destruction that derives from an economic paradigm that has not yet
internalized the need to assess the environmental impacts of new technologies
and products.
It is clear that the hunger for economic growth and wealth pushes
business and governments to ignore environmental impacts that are considered an
inevitable byproduct of development. But this fails to account for the costs
that will inevitably be borne when the damage must be cleaned up.
A more
careful production process with pollution control technologies may cost more in
the short run, but it saves money in the long run.
"In
a more crowded world with more and more technology being developed that can
damage living fauna, flora and beings, we need to understand the full impact of
the new technologies we are developing,"
Cohen writes. "This requires
a deeper understanding of earth systems science and a deeper understanding of
the main and side effects of all new technologies."
