Malvika got a gift from her company as part of Earth Day. It is a shopping bag that easily packs into a small size and can be fitted to your key chain, your belt or back pack. This solves a major problem I have been having with avoiding plastic bags i.e. remembering to take my own shopping bag. Great example of what you can achieve when you apply your mind to a certain problem.

I for one have attached the bag to my car keys. A couple of weeks from now, I should know how useful this concept really is.
