This might be a dumb question, but: why don't we do glass-style bottles? I live in America now, but when I used to live in Pakistan 20 years ago, I remember that I would buy pepsi or coki in a glass bottle... and if I wanted to buy a second one, I would go back to the store and give them the old empty bottle, and they would compensate me a few pennies for it -- and the bottle then is presumably washed and reused. It's simple, fun, and environmentally friendly. Why don't we do this with... milk, juice, etc.? Why not do this with everything really?
