For years, many marine biologists have argued that the floating, open-ocean net pens that produce billions of pounds of salmon per year also generate pollution, disease and parasites.

Having groceries delivered can cut carbon dioxide emissions by at least half, compared to driving to the store, according to a new study. That's because the delivery truck offers the equivalent of a "shared ride" for the food.
