The math is simple. If you throw away one less bag of garbage each week, you'll contribute 52 fewer bags to local landfills over the course of a year. But how do you create less trash if you're already recycling? Start by cutting down on food waste, which constitutes a quarter of all waste entering landfills. You can do this by freezing, creatively re-using or composting leftovers. Another way is to buy reusable, recyclable and bulk products, as well selecting products with the least packaging. Finally, try to purchase fewer things, period. Ask yourself, do I really need this? Listen to your gut and lighten your garbage can today.
