For example, yogurt. Ubiquitous. Comes in nice little plastic cups, which will, at best, end up in a landfill. Suppose there is a wide agreement in society to phase these plastic cups out:
* Do we ban yogurt?
* Do we use recyclable glass instead?
* Do we use recyclable glass, and only dispense yogurt if you bring a recyclable container for an exchange?
* Do we use recyclable glass, only dispense in exchange for a recyclable container, and standardize container shape such that the recycling actually recycles, as opposed to sending the "recycled" container to a landfill anyways?
* Do we limit the amount of yogurt containers one can buy in a given timeframe?
* Do we create a heavy tax on the container, say 10x the price of the content?
Life is short and people may get overwhelmed by too many details. Problem which compounds if there is too much choice. Almost always better to have a standard recipe to follow, than having to figure out a recipe on a case by case basis.
