If you're using food storage containers that are made from safe plastics, no need to do a total kitchen overhaul and throw all of your plastic away. It is a good idea, however, to start making a gradual shift over to glass containers. There are a lot of high quality and affordable options out there. The best are those that are made completely of glass, including the lids. When taking food on the go, try glass containers that have snug fitting plastic lids -- that are BPA and PVC-free, of course.
