Photo by Amber Bracken @photobracken | They say oil and water don't mix but that's not really true. While water and oil don't readily mix, depending on a range of complex factors, including temperature, type of petroleum product, salinity, and amount of agitation, spilled oil can become irrevocably mixed into the environment. In the same way, when oil's product plastic gets into the environment it can become so fundamentally a part of the ocean, that micro particles of it are accumulating in the bodies of marine life. These micro plastics are now being found in human bodies as well and the health impacts are still being studied.
For decades, the conversation about plastic and sustainability has been centered on recycling but the much larger issue is how much plastic we are using for often frivolous applications like single use plastic bags, forks, straws, and toothbrushes that we throw away several times a year. A lot of this can't or isn't being recycled and, as we all know, ends up in the ocean. What we actually have is a consumption problem that requires evaluating how we can best use the limited and valuable resources available to us and the conversation should begin at extraction.
