You don’t have to use the canvas one 200 times. It’s more like 130. And less if you use nylon or hemp or anything less energy costly than cotton. But yeah, if you want to reuse your throwaway bags, go ahead. It’s certainly a greener option than throwing them out.

It’s not “eco-theater” to want to reduce the ecological cost of bags, though. Not is it “eco-theater” to want to keep millions of plastic bags out of the oceans and rivers, or out of storm drains where they cause clogs, or out of bushes and trees where they are just ugly.
