Another example of relative success: I don't know how it started but I and many others still remember to cut the plastic rings on six-packs before throwing them out to avoid turtles from getting stuck in them if they end up in the ocean. Your grandmother's actions have been more consequential than mine, my discarded plastic is extremely unlikely to end up in the ocean and if it did, it would still look like a jellyfish that a creature would try to eat.
