Thanks for the comments and thoughts Joe. Yes, this topic is difficult to think about, much less discuss with those who have never really considered the issues. Actually, I think that some types of growth will continue long into the future. For example, recycling businesses, or companies selling products that will replace others (like scooters replacing cars) or maybe products that offer better efficiency and sustainability. I would love to live for the next 500 years to see how this transition plays out. It won't be pretty, but it may be very interesting!
