Carbon Footprints World Wide

Ways to Reduce Our Carbon Footprints
• Take public transportation, walk, ride a bicycle, carpool• Switch to an electric or hybrid car• Less air travel• Use energy efficient lightbulbs and appliances• Recycle and reuse stuff• Don’t be wasteful• Eat food grown locally• Eat less meat
– If your four-person family skips steak 1 day a week [for a year], it’s like taking your car off the road for almost 3 months
