Wouldn the Earth become polluted? There would be unlimited exploitation of the planets natural resources, surely?
Don’t forget that there would be unlimited progress in all areas, including technology. There would be no stopping the development of cleaner, greener energy and for cleaning up the world, unlike today, where fitting, say, sulphur-reducing equipment to a power plant costs big money. Today, it costs to be good. Cleaning up polution is a part of the financial equations of businesses and governments. Money used for the environmental good can not be reused for something else, say, product research and development, marketing and so on.
