Some tips for living an eco-smart lifestyle:
Do Some Solar Sums: Choose a solar-powered calculator rather than one that relies on chemical batteries.
Use Recycled Foil: Because aluminum foil has a major environmental impact during its production, be sure to use 100% recycled foil.
Body Beautiful: Go for plant- rather than petroleum-based products; they're more natural and require a lot less processing.
Return to Maker: Buy from a manufacturer who will take back your old computer and dispose of it. You'll be supporting a more responsible approach to e-waste.
