In California, 400 plastic bags are distributed every second--14 billion bags per year. One of them managed to find its way to the top of the lemon tree that is growing behind my house. I see it when I go out to pick lemons, but unfortunately, the bag is too high up in the tree for me to reach. I don't remember when I first noticed it, but it's been there at least all summer. I wonder if the Santa Ana winds forecasted for this week will send it flying into another tree, or to the ocean.
