I believe plastics are an environmental problem, and I am sure these disposable bags contribute. They make for highly visible irritating litter for sure. However a lot of engineering has gone into reducing the plastic content of these bags, it really isn't a lot compared to other things we use and throw away.
However when I hear things like this I get a bit skeptical. I suspect Walmart could be doing this as a feel good marketing ploy as much as to protect the environment.
What will be the impact of the reusable bags? They appear to me to contain more plastic than the disposable ones, how long does the average one last? What is the typical fate? Has Walmart or anyone done an net environmental benefit of this? I doubt it.
This quote comes from the article, Walmart says:
"Customers will be encouraged to bring reusable options from home to carry out their purchases. Low-cost, high-quality reusable options will also be available for purchase, if needed."
So I suspect Walmart will profit from these new "Low-cost" reusable bags, as well as from any customer goodwill this generates.
Oh well, maybe I am wrong and just turning into a curmudgeon in my old age...
