It is actually a deliberate corp strategy. Plastic straws were never a real concern, save for that ONE turtle. Plastic straw make such a negligible amount of plastic waste that stop using it will have virtually zero measurable impact in amount of plastic waste we create. All it ever was intended for was to make us feel like something was being done while doing absolutely nothing.
That’s not to say all plastic reduction initiatives are pointless. But the straws definitely belong in the least environmentally impactful category.
