The first point is population. Steffen points out that the population by 2050 will be somewhere in the vicinity of 8-9 Billion, possibly more. with just about every person within a days drive of a major city.
sustaining an exploding population with our current reliance on energy will be increasingly difficult, let alone by replacing our current technology with less advanced (but much cleaner) energy solutions.
It becomes blatantly obvious that some serious energy cutting measures need to be implemented if a sustainable society is to be achieved.
even in our current society, creating a denser environment can cut transport energy costs by up to 90% as lengthy travel no longer becomes a necessity.

Linking with last weeks tutorial findings, our group noted that the current urban sprawl is bad for the natural environment based on the assumption that the infrastructure that we build is bad.. changing the assumption (by building and living in a sustainable manner) would create an urban sprawl that would be great for the natural environment.
Steffen touches on how this could be done, stating that raising the average density has the same effect. This means that you can focus your efforts on creating certain areas that are hyper dense and maintain the rest of the urban fabric to achieve the same results. Steffan refers to this as tent-pole density. Not only would this be much cheaper and efficient, it also strongly supports our initial template of a future brisbane and a potential template for the future of the Paddington site.
