If it’s convenient, or makes the average person’s life more comfortable, some enviro-nut group will want to ban it and some leftist politician will accommodate the group with yet another law.
The next enviro campaign will inevitably be for paper bags to replace cloth bags. First, you have the use of all those fertilizers and pesticides needed to grow cotton. Then, you have the use of child labor in sweat shops to sew the bags, while paper comes from an enviormentally nice and renewable resource, trees, which also produce habitat for Spotted Owls.
Environmentalism is just another kind of mentalism.
