The scale of an individuals effect, depends on how many other people do "it".

As one example, if l was say "No thanks! I've brought my own non-plastic bag" to the retailer asking if l want a (plastic) bag, that action didn't stop that plastic bag from being manufactured.

But, if 90% of people stopped using the retailers plastic bags, that retailer would order less plastic bags.

Scale this up on a population level (& do the math).
