Who says it’s not easy being green? With simple suggestions from Francesca Olivieri and Susan Gluck-Pappajohn, the ecomom founders of Sage Baby, every day is Earth Day. One-Two-Three Turn off the lights when you leave a room. Turn off the water while brushing your teeth. Unplug your cell charger when not in use. Toss the Toxins Replace cleansers and detergents with earth-friendly versions, like Seventh Generation’s dye-, chlorine-, and phosphate-free household products. Shop health food stores for shampoos and creams made without synthetic fragrances and parabens. Clean Water Ditch landfill-clogging plastic bottles for a sleek, reusable, toxin-free stainless steel Klean Kanteen. The Kid Kanteen is perfect for backpacks. Paper or Plastic? Neither. Hold the shopping bags and tote purchases and kid paraphernalia in a compact, nylon Baggu sack. Pack snacks and lunch in reusable containers and use wax paper bags made from unbleached paper instead of plastic baggies. Buy the Farm Join a CSA (Community Supported Agriculture) to support family farms and get locally grown produce delivered to your neighborhood. You’ll get seven to ten kinds of vegetables each week, which adds up to 40 organic, just-picked varieties during a season. See? Green really is your color.
