My Scottish friend misunderstood the American grocery clerk when she asked "Paper or plastic?" He thought she meant "cash or credit?"
Europe's a "greener" continent than America where shoppers bring bags or pay for them. No wonder he misunderstood.
That got me thinking: "paper or plastic" seems like an insignificant, personal choice, but it has long-range effects on the environment we all share.*
Actually, most choices, even seemingly insignificant ones, have consequences. Few are strictly personal.
We say it's no one's business what we choose to do in our personal lives, sexually, environmentally, socially, or financially. But life doesn't work that way, and moral choices affect our environment in the same way ecological choices do.
That's why, in all areas, we Christians should lead the way in making Philippians 2:4 choices: "Each of you should look not only to your own interests, but also to the interests of others."
* I'm not saying we should never use plastic bags. I often do. But I'm trying to think through even this simple choice.
