Amazon sells these neat shopping totes called the Baggu. I try to reuse shopping bags, or bring a cloth bag, but a lot of times I get lazy so I just leave the bags at home. Well, maybe that’ll change with the Baggu. I haven’t purchased any yet, but they look like they might be the answer to my laziness. They fold up so your can keep one in your pocket. When you expand them, they’re the size of 2-3 regular plastic bags. Neat! They’re washable and have a somewhat flat bottom so things will sit in them more easily.
Millions of plastic bags end up in land fills, and they don’t biodegrade. They just turn into toxic materials that kill wildlife and pollute the air. So these are a great idea.
