It would be nice if it were just a case of a few problem countries. Unfortunately it is not, nor is it easy to draw lines. For some time, Western countries shipped our waste plastic to China. When China closed their borders to much of the plastic, we found other places to the east to ship it. Just because you've got someone in another country ready to spread your plastic about for you doesn't mean you're disposing of it responsibly. With that said, although Indonesia and parts of Asia are hot spots for microplastic contamination, the Mediterranean is just as bad and the East Coast of the US is not far behind.
All NoPlasticWaste is talking about is a small increase in the cost of plastic goods (1/10th of a cent on a disposable plastic cup), so that we re-use plastic to make more plastic rather than starting with oil.
Even if a person were to believe they have no role in creating plastic pollution and believe that their country was not responsible, there is still good reason to support closing the loop and reusing plastic. We are just beginning to understand how microplastics move through ocean currents and food chains, how extremely widespread they are and how they can undermine basic biological processes, such as endocrine function. Supporting reducing plastic waste, keeps the ecosystems we sail on healthier. The last thing we need right now is lower ocean biomass (even just to feed ourselves) and simpler ocean food chains (less stable ecosystems). At the very least, supporting reducing plastic waste means a cleaner, more reliable food supply for you, wherever you live.
Every week when I put my blue box out, I think about how nuts it is that a good portion of that box will just end up dumped in a landfill or shipped offshore. Aluminum is one of the most recycled materials in the world (75% of the aluminum ever produce is still in use). It's that way because it is cheaper to recycle than to start anew. Why not do the same thing with plastic?
