I've been thinking a lot about harm lately, and unintended consequences. you cannot live life without causing harm. and it's not even as easy as trying to live causing the least amount of harm possible because sometimes it's impossible to weigh.
at our office, sometimes even deciding where to eat brings up a lot of questions. do we get slightly better tasting burritos at whole foods which is owned by amazon which annually produces nearly as much carbon as swizerland or denmark? not to mention all their terrible workers' rights issues, and lack of paying taxes. or do we get not as tasty burritos at chronic taco which probably also does a lot of terrible things that we just don't know about because they're not as closely scrutinized as amazon?
and that's just lunch! where do you stand on bioplastics or the conventional kind?
a lot of people would say, bioplastics, of course, because it doesn't come from petroleum, and it has a smaller carbon footprint because most oil doesn't come from america anyway. but that's just the oil aspect. most bioplastic in the states is made from corn since we have govt subsidies for that. but it's those same subsidies which ultimately led to high fructose corn syrup in everything because we have too much corn and the govt asked scientists to come up with ways to use it up. and, while both oil and corn require water, corn requires more land and possibly causes more water pollutants because of fertilizers and pesticides. oil has led to war, which farming hasn't as much, but our modern conventional farming has led to hella cancers and also involves migrant workers / illegal immigration issues which oil likely has too much definitely on a smaller scale.
end of life is murky too. bioplastics are rarely recycled or composted. in fact, they actually contaminate regular plastic recycling and most waste haulers don't even want it. almost all bioplastics end up in landfill where they don't biodegrade at all, but do release methane, which regular plastic doesn't. methane, of course, contributes to increased greenhouse gases which aggravates climate change.
so, which is better? well, they both suck. just in different ways.
I tell the customers to decide what matters most to them (for me, i sacrifice taste and eat at chronic because i don't like to support amazon), and not worry too much about the rest. i also suggest they do research so they can make informed decisions, but as demonstrated above, sometimes it's the knowing too much that makes it impossible to make decisions!

i also want to emphasize that a lot of the bioplastic on the market isn't even 100% plant based plastic. something is considered bioplastic even if it's a blend of plant based and petroleum based plastics.
