Again banning the plastic bag is NOT the answer. Education on recycling the bags is the answer.
I would go as far as supporting the making of by-laws that prohibit using store plastic shopping bags as garbage bags and by-laws that enforce that people Must recycle the bags after they are done using them (which could be a while cause you can keep taking them back to the store until they are worn out and full of holes)
If you want a plastic garbage bag, then go buy a box of them at Walmart for 3 or 4 dollars.. I get a box of a hundred proper plastic garbage bags at Walmart for around $4 buck that are designed for that sole purpose. That lasts me about 8 months.
As I have said their really is almost no such thing as a single use plastic bag. The Only plastic bags that would be single use are ones used to collect body fluids, medical waste, and pet waste. Imagine if everyone simply Recycled their plastic bags. It's such a simple thing to do.
Plastic bags have been recyclable and or compostable for at least the last 20 years, if not longer. This includes the ones you get in the produce isle to put your veggies in. The bags have also always been marked with a recycling logo.
There are several technologies that are in place to recycle plastic bags that have been around for a long, long time. Recycling education is the answer to the plastic bag problem.
