Vertical farms solve land problem

1. there is no land problem, there is an energy problem, a fertilizer/chemical pollution problem, and a pernicious unsound money problem
2. Yeah no yall got me messed up. If you can see, they are not using any safety, no gloves or nothing! So nobody knows if those guys ich their ass an pick your greens or get a cut an get blood on the greens. YEAH! Good job you guys! Real smart! #Osha
3. Hola
4. i want to do this on a smaller scale!
5. Good idea, however, you cannot replace the minerals the plants uptake from the soil that the human body needs.. I would be curious to know what the nutrient value of hydro grown vs soil grown....
6. how the fuck do you patent a rotating wrack?
7. I have not been getting information about the gas that was discovered under water in israel I . believe there was mixed feelings as to ownership of the valuable commodity
8. Recycle Water!?! :P
9. So awesome!
10. OUTRAGEOUSLY SMART!!  Very good for people and the earth!
11. I love farming and like to grow Hydroponic Lettuce & etc on my Land in China Hainan Wenchang..
12. Yes... we can!!!
13. land problem LOL aahahhahah
14. LOVE,
15. actually watch the video there not "towers" theres no shadow cast walter0bz I'm a farmer and this is the future. I work as an OG biodynamic farmer and i am all for cities and other metropolitan areas who can't rely on sourcing there food from outside sources, think about the effect shipping goods to the city has. Besides other then us Organic famers nobody treats soil with respect and honestly this may fix that as well...
16. to carlsm95 your right on but good for you to know we already do have all the answers when it comes to food fuel and clean water for a much larger population on this planet. Thorium LFTR reactor , Omega Garden's Farmdominium, and graphene desalination. cree has some new led's that are 273 lpw that came out in feb. and for cheap space travel breaking low earth orbit which will be 100 times cheaper will make space travel happen much quicker. and for actual space travel use vasmir propulsion paired with thorium reactors, we could mine our whole solar system even go to new solar systems.
17. We can get meat too when we make grain farm and stuff :D and animals in skyscrapers dafuq :D
18. aren't building materials more scarce than soil. these might make sense in extreme corner cases but they wont scale. towers cast shadows, and the area of light captured is limited by the area of the building . if you had fusion for powering grow lights maybe. we just have to accept earth has a carrying capacity and stay within it.
19. why is this patented? he wants "to the sell the technology"? its an ancient system, damn people are greedy 
20. Since you've really strayed quite far from the original topic and I honestly don't have the time to prolong this discussion, all I can say is I completely understand and respect your point of view. While I could never claim to have all the answers for humanity's problems, I hold on to optimism and faith in our ingenuity because it's gotten us so far and allowed us to defy nature in so many ways, and it's my sincere hope we don't fall into another Dark Ages...
