One green thing I wish everyone would do:
Give up plastic bags. It’s hard, I know, to remember to carry a bag into a store. I wish we could give up other forms of plastic, like the blister packs encasing everything from Barbie dolls to Bic pens. Back in the days of five and ten stores, it was so nice to simply pick an item out of a bin or off a shelf, pay for it, and not wrestle with tin snips to get it open.
