Most people do not have the cash to jet all the time. It seems to me that the biggest offenders are the ones who fly often, such as business travelers who could teleconference instead of flying. It doesn't really matter anyway since China (the world's biggest polluter) is not concerned with emissions except for temporary pursuits such as cleaning up for the Olympics.
Living in the inner city seems like good idea on the surface, until you consider the higher crime rate, higher pollution (cancer risk) and the fact that not everyone wants to live in an apartment.
Speaking for myself, I never asked for plastic anything. Manufacturers did this to save a buck, not because anyone necessarily liked it. Generally, I have found that many things that used to be made from metal which are now plastic is cheaper, but inferior in quality. Plastic also contains chemicals that have been suspected of leaching into our food. I would welcome its demise.
As far as the electrical devices go, great idea. It helps everyone.
On cell phones etc, mfrs. need to find other materials to use in their products, and/or recycling needs to be as easy as possible to promote the masses to adopt it as a lifestyle.
