agrow building to fed the world by mike d sollows

we in this day in age no longer need to farm outdoors where millions of tons of pesticides and fertilizers have contaminated the soil and fresh water supplies around the planet,by building huge agrow buildings that are 100 strorys high and have 1 miilion square feet of grow space per floor could grow surar cane to be dryed out and processed and fermented into pure alcohol fuel that would burn clean and be abel to power a huge steam turbine generator that could run the whole operation and if this building was built up by slave lake where the soil is no good for crops but yet there is a huge water supply that could be piped into a reverse water osmosis system and then distilled to be purified water and by using hydropontics the building could produce 40to 70 yeilds  climate controlled grow floor this clean and organic food would need no pesticides and no fertilizer only constant monitouring of the nutrients needed to be added the air intake could be filtered with a water filtration system and the water purified and by using hydropontics lighting and grow tabels the whole system could be auto mated with just a small number of people to monitour the operation, the food grown could fuel the system making it self sustainabel and the food produced to could feed huge populations of humans and live stock in a clean and humanitarian way, the agrow building coud have on site operations for food and packaging and distribution, the jobs this would create would be enormous and the cost of food would be very cheap and very productive with so many yeilds per year with no pesticides and fertilizers destroying our rivers and lakes and water tabel as outdoor farming is so contaminated it is going to be the end of us, I know a building this big would cost a fortune but to do nothing would be worse, all the peole have to be united to acomplish this kind of venture but if we let the industry and energy giants run the worl much longer we will pay the ultimate price
