I remember those days, not too far in the past, when we all used cloth bags to do our shopping. Suddenly everyone was using plastic bags. Fast forward 25 years and we now know that plastic bags are bad for us. We are being motivated to use cloth bags again.
Our reckless material consumption is under serious attack. Our eating habits are being criticized more and more. This wikipedia article calls all modern diseases as diseases of affluence; diseases which are result of getting rich.
We need to think. What are the other things we are doing wrong? (No hints today. :))
