And all of the human advancements in sanitation, food safety, and transportation energy afforded by plastics? You'd significantly increase CO2 output of transportation if every plastic item was replaced by something heavier. Stopping all plastic production would be very harmful.
As for people bringing reusable containers to the store, this was stopped because it's a health hazard.

The pollution negates the health benefits of sanitation and food safety though, especially in the places where they are dumped, which are in rural communities in developing countries, whose people are somehow expected to make a living out of it for themselves and for their children.
Besides, there are so many uses of plastic in food packaging that aren't even necessary to begin with, and which shouldn't exist. How much of single-use plastics are just bags of unhealthy junk food and candy wrappers and carbonated soda? Is it even necessary to have such a large economy based on unhealthy food sources?
