we dont have enough natural and renewable resources. unless we are going to find ourself a house in a high density 'sustainble' neighbourhood that rations water, pay astronomical rates for power, still have two cars in a walkable neighbourhood and get caught in freeways to work 30 miles from home with a 2 hour daily commute. towns full of children and not enough schools. old people and not enough open spaces. increasing public sector pension liabilities and sinking into debt every year. this is happening in every part of the world. except countries with a low population. i think 5-7 million is the magic number for resource management purposes. take NZ for example. 5 million. sparsely populated. high density in north island/auckland. i doubt if it would be called 'sustainable' or 'smart'.
