I actually think it's because the most common phrasing is "reduce, reuse, recycle", the pronunciation of which comes out as "re-duce, re-use, re-cy-cle". The 2-2-3 cadence just sounds more natural than 2-3-2 or 3-2-2.
that's lovely, but thats not the point ;) first you try to not buy it. if you have to buy and have extra garbage, try to do something with it to avoid disposing. if you can't, then try to recycle it. it makes sense
It's important people start using more ecological solutions to package and carry stuff around.
