check out that website, but then also do a general search for 'vertical farming.' this relatively new idea has been all over the news lately. to solve our current and future problems of, not only having enough healthy food to feed the ever growing human population (birth control, people), but also provide city dwellers with fresh, local food, we need to radically rethink the way we grow food. vertical farming would take up less land, thus putting less pressure on deforestation and habitat loss. a farming 'high rise' could be in the middle of the city, not an hour or two away...people would have no excuse for not eating healthy, fresh, local produce. having a farm in a city would also allow people to be more involved in the growing process. they could volunteer 'on the farm' a few hours a week....planting, weeding, watering, harvesting. they could realize how much work it takes to run a farm and appreciate farmers more. there are a huge number of benefits to this idea.
i am sure there are disadvantages to this idea, as well. it could be very expensive to initially create a vertical farm. it would use a lot of electricity to give all the plants all the light they need. how would plants get pollinated indoors? the website says there would be no pests, but what if a bug or fungus attacked a crop? what is to keep it from attacking all the crops? and since the crops are in such a small place, it seems it wouldn't be long before everything could be wiped out
the people who came up with this idea might have answers for all these issues...i hope they do. i think a lot of problems could be solved with this one solution.
