A vertical farm is a concept farm which is planted on levels or floors.A sky scraper type building can house a vertical farm.Since the garden is built upwards，rather than outwards，it requires much less space than a conventional(传统的) farm.

The world is quickly running out of room for conventional farming.Vertical farms could be a key to this situation.An 18?story vertical farm could feed as many as 50,000 people，all in an area which is the size of the average city block.Vertical farms in the city could cut down on transportation costs as well.Think about the amount of fuel it takes to transport food from farmland to city.The resources saved would be surprising. Besides saving travel time，food would be delivered in fresher condition and with less damage.

There is a growing concern about the use of pesticides in agriculture today.But the vertical farm would be a greenhouse type environment, avoiding the need for a large number of pesticides.Vertical farms can be built in a contained space，therefore they are an excellent solution for living well in an environment far different from our own.Hydroponics(水耕法) could be a big part of vertical gardening.This would reduce the amount of soil needed to grow food.Of course，not all food does well with this type of planting，but there are many crops that actually seem to do better.

In some climates，a lack of sunlight creates a short growing season. The solar power option may not work as well here.The addition of grow lights would make it possible to grow crops in vertical gardens in these areas.In other words，we could grow crops in areas where we never could before.

Vertical farms may just be a concept for now，but they are a concept that will solve many of our problems in the future.
