Good example of an ecosystem map

"Agriculture made towns and cities possible, made it possible to meet and associate with far more people than was possible in hunter-gatherer tribes. Eventually, poets could meet poets, artists could meet artists, and musicians, musicians. The potential of a group of competent musicians is so much greater than the sum of them all in ones and twos. But large cities have been with us for thousands of years now, and somehow the advances brought on by civilisation seem to have run dry, and urban decay has begun to manifest. Provided that people can still communicate and work together, the next step forward in human cultural terms might well be independent from physical proximity – it might be through association by choice. Perhaps now is a good time for the better application of those information technologies that have been developed in recent decades, in supporting storage and reuse: not of food, as in neolithic times, nor even of money, where information technology applied to finance has enabled both wonderful and dreadful things. It is now the turn of personal information to be the focus of the new technology – information technology – so that we can present ourselves and the values we have chosen to others, and let that information be used for the further positive transformation of society."
