Farming of the Futrure

Here's an interesting way to have a farm. For some reason a garden skyscraper just seems wrong. Sure you don't have to worry about contamination or irrigation issues, but to me it seems a little unnatural. I'm used to seeing the tractors and farmlands spread across America as you drive down the road, but this may be something that will become popular as the population of the country grows. We may need to get rid of some of the farmland for housing in the next century and have skyscraper farms. It's a really cool idea, but I hope it happens no time soon.
