Overall, getting rid of disposable plastic bags in the environment is a good thing. However, carrying around bags, I fear, will be one more thing to devolve onto women; men will likely pay for the bag. Women already carry so much and do the bulk of the shopping. An alternative that would better serve customers and vendors would be to use biodegradable plastic bags. The technology is there. The price will come down as demand increases.
Curious: will men shlep bags happily/easily? It’s one thing to have a car and keep bags there all the time. I live in an area where everybody drives. It’s another thing in a city environment like Manhattan where most rely upon public transportation.
On another note, remember that it is incumbent on Jews to protect our environment. Encourage recycling and judicious use of materials. We throw away so much stuff!
