"...the way natural ecosystems work is exemplary: plants synthesize nutrients which feed herbivores; these
in turn become food for carnivores, which produce significant quantities of organic waste which give rise to new generations of plants.
But our industrial system, at the end of its cycle of production and consumption, has not developed the capacity
to absorb and reuse waste and by-products. We have not yet managed to adopt a circular model of production capable of preserving
resources for present and future generations."
Recycling is a relatively simple way to reduce waste production. It not only keeps materials such as plastics out
of landfills, but creates a large supply of materials for use. There is only so much petrolium on Earth, in effect, only so much plastic we can create.
This finite and rapidly dwindling resource is destroyed when it is used for fuel but many "waste" plastics that have served their purposes in their
current forms are still perfectly good as raw materials. They can be melted down and used to create new products making the production of new plastics far less necessary. Recycling plastic is also much cheaper
than the full process of synthesizing new plastic. It seems logical then that governments and businesses would be eagerly taking advantage of already existant
plastics to create new products. Instead, 86 percent of discarded plastic in the United States ends up in a landfill (
Cho, 2012). To put that another way,
in 2010 America had a 34% recycling rate, producing 250 million tons of waste in the year and recycling or composting only 85 million tons of it (
EPA, 2010).
Plastics can never truly decompose. Over time they simply break into increasingly
smaller pieces until they form microplastics, tiny beads of plastic that often end up in the oceans. The Great Pacific Garbage Patch is made up almost entirely
of microplastics which kill microorganisms by blocking sunlight and poisoning larger organisms when they ingest the plastic (
National Geographic). Plastic
that makes it into the environment, whether placed in landfills or left somewhere in nature, will never go away. Plastic's lack of degridation
could be used to our advangage though. Since many types of plastic can be reused, we already have a huge supply of plastic on hand, it just
needs to be processed. This would prevent both more plastic from getting into the environment and wasting patrolium and other resources on producing even more plastic.
