Being a 'greener' and having a 'greener' son opens us up for lots of unconventional ideas on how to save/protect our environment. Maybe your this way too or maybe your a bit overwhelmed by the idea of it all. We started very small at our house and I think the easiest way is to use eco-friendly shopping bags. There are tons of ways and tons of styles to do this... we love the bags that stand up like paper bags. Then my all time favorite... the chico bag, ahhhhh how I love this little thing. Wraps up so tiny and small I don't even notice it in my purse and yet I ALWAYS have it. We also love these little net bags... they work very well for fresh produce. When we shop at our warehouse store and need big bags there is nothing like the IKEA bag... so cheap to get and they work and last FOREVER!
