I am wondering - did you listen and watch that video carefully? He says the department of agriculture will be located at the center and the food will be located there. So essentially an office and a food storage place(like stores without cashiers). A store does not equal food security - where will you replenish that store from when a drought hits and your farms are done? He mentions briefly a strip of agriculture in there and that's about where it stops. Good old monoculture farming has failed us for thousands of years. And if you grow a food forest not only will you not need to water it further - it will actually increase local rain fallout giving water back to the system. If you note the kinds of trees he also plans to put all around the suburbs - all sorts of 'pretty'(his words..) plants and things. No edible plants in the suburbs - he isn't concerned with how far you gotta travel for food or how great fresh food is (only conerned with how far you gotta travel for social functions). On top of that he has lawn all over the place. Lawns are a huge waste of land and take a lot of water and manpower to maintain.
He plans to monitor and clean the air and the water via computers and recycling tech - instead of using permaculture methods and wholesome designs of bioremediation and other such tricks (which are already being used slowly but surely in places like Florida) which do not leech energy (a topic which seems to be avoiding alltogether - solar is not going to provide you manufacturing and recycling power - only sustain the housing units) and connect us to the land.
well, he claimed a hydroponic system in the center for one of his designs, however...
It would be far more efficient to use solar, wind and hydro-power, and recycled organic material to run larger farms outside the city then the methods currently used....... mind you, as a vegetarian and with a cold and calculated mind, I view the world being a much( MUCH) better place without livestock. cows alone destroy so much farmland, and that is just cows, not to mention all the corn (that they shouldn't be eating, or for that matter, corn in general is a horrible thing in our society) that needs to be grown just to feed all this livestock.... i personally think it would be better for the environment, better for the animals, and better for us, and would yield more food, if instead of focusing so much on livestock the world focused on plants. but i do understand that people love meat for some reason... but really and honestly, the world would benefit greatly from switching over to minute livestock farming and primary fruit and veggie. (I'm not saying to get rid of it all the way, i am just saying fruit and veggies are better for the world, grow more edible product per space needed to produce)
and building a system that would clean up the ocean and harvest energy.... i mean come on.... that would be great!
imagine, you harvest energy, clean the ocean, (promoting wildlife to flourish in the ocean) and lift a big weight off our reliance on crude oils, giving us less of a reason to drill in the ocean... I am all for all of this.... and i honestly do believe it is doable.
in these designs there is easily enough room to put up a LOT of solar panels, and it would be lead by technological advancement. think about that.... instead of pumping our efforts into war... we could pump it into making sure every single house had the absolute best solar panels science can make, with all the extra energy from every house and building you could easily power manufacturing plants, and if you planned out the designs of things well enough, the entire recycling processes could be changed from a struggle to a easy simple procedure (like glass soda bottles, just re send and they are re-used after being cleaned.)
i honestly think this is doable..... however i don't think society is ready for it or will accept it. not yet.... this is kind of like living like a machine.... id be willing to do it, just out of my love for science and knowing it would make the world healthy again, and id probably be happy as hell! even if they took away all doable narcotics...... and that's saying something.... i love my weed, but if giving up my weed meant the world could live as it should again i would do it.... probably try and sneak weed in though... just saying.
and hell, just like Il said, not hard to produce a LOT of food on a farm. ESPECIALLY if you have a means to design a system with no limitation from lack of money.
