While it’s cool to be single, we’re big fans of carpools and not such big fans of single-serving products. An easy way to go green is to put your foot down when it comes to solo-packed snacking. A snack pack of crisps or a granola bar may seem like an easy way to quench a mid-day craving, but the trash produced ends up in the dump. Stick to easy-to-carry fruits (like apples and bananas) or buy almonds, chocolates, and rice crackers in bulk for snacks that carry a double no-guilt serving: one because they’re healthy, and another because they’re less waste!
