Oakland is set to follow San Francisco’s ban on plastic bags at retail stores grossing more than $1m. But surprise, surprise (not!) the plastic bag industry is cranky, filing suit over the measure. Countless plastic bags end up in our ocean, harming marine wildlife. Even China, a country that reportedly uses 3 billion plastic shopping bags a day is moving to ban ’em. I say – BYOB – Bring Your Own Bag, whenever you can.
