Remember the Tupperware parties people had at their homes to get you to buy more plastic? I use glass now instead to avoid plastic containers. We rely on plastic way too much in our lives. The process of creating products we use often have chemicals added which can negatively impact our environment and our health. Plastics have chemicals that can possibly enter our bodies and create havoc. The Ecology Center of Berkeley, CA has information on plastic and the effects. Why risk it when there are many other options out there now.
Start looking at what plastic containers you use and begin to replace them with glass or stainless versions. I love the Ikea glass containers or just use canning jars that are available everywhere. I use both!
