Even the UN stands up for a ban on plastic bags (so we’re well past the mainstream acceptance that bI'm not usually one to point to large institutions and suggest leadership. And perhaps I'm not doing that here... maybe we're years past the stage where the word "leader" should be associated with any entity making a stance to ban single-use plastic bags.
After all, countries as large as China weighed in on this issue awhile ago in support of similar measures.
This time around it's a representative from the United Nations.
"Single use plastic bags, which choke marine life, should be banned or phased out rapidly everywhere. There is simply zero justification for manufacturing them anymore, anywhere" (more on that story here)
I don't mean to disrespect the United Nations with these comments but rather suggest that they, the intersection of interests from cultures around the globe, have a very challenging time agreeing on issues. I'm glad to see movement from them on this issue.
