i always know the day be come . we all know . there only so much oil in the ground and and one day we will run short . but isn not there suppose to be enough coal to use instead . and wind power and or something . thing for future generation to worry about . then this documentary hit me smack between the eye . oil make the fertilizer that be the reason for the first time in world history practically no one live on farm . when the inevitable oil shortage hit and a lot of thing air travel and many drug and plastic and life in the suburb will become impossible . but the crazy insight from the documentary be this represent oil give u so much energy with so little effort and that without it our life must change . even if substitute and conservation be implement immediately and at best they will smooth our land into a strange post oil world which ( the documentary claim ) could be start now . despite it gloomy message and the documentary be often highly entertain . it contain fabulous historical footage ( sober image of dark urban factory and and campy funny stuff from the 1950 ) which remind u of why we move to the suburb in the first place . it also offer hope that a massive effort start now could both ease our transition from oil and make the world a good place . my only complaint about the documentary be that it do not spend time on the mystery of why we be find this stuff out now . how can this be a big emergency all of a sudden . we know in the 1970s we should be prepare for a post oil world and we start to prepare with alternative energy research and small car . if our failure to follow through on president jimmy carter initiatives 25 year ago have doom u to a hard landing in a post oil world and why be no one shout about it on soapbox . in the end i find the documentary highly persuasive while and it leave me with the terrible chill of be drag out of a very lovely dream . this be must view for everyone not afraid to face a very likely near future that we still have time to do something about . charles .
