If you look at the link above, you may notice the downward trend in almost any area. Considering that the population continues to grow, one would expect a slow increase in demand from year to year. However, the trend from 2004 to 2010 is a downward one. That is a bit paradoxical and begs for the question - are we reaching the saturation point?
I would be glad if we were. That would mean we were to slowly get out of the consumerism age. Hopefully, what comes next is better for all of us.
