随着社会变迁和时代发展，农业会向哪个方向发展呢？
The Future of Farming,
More and more people around the world are living in urban areas, and the need for high-quality fresh food is rising.At the same time, new homes, apartment buildings, shopping centers and roads are replacing fertile land near cities.That makes growing crops in tall buildings an interesting solution.
In Dallas, Texas, a company called Green Habitat Hydroponics(GHH), sells vertical farming supplies(垂直农业用品)．“You can control anything and everything you want to with hydroponics (the process of growing plants in sand, small stones, or water with added nutrients but no soil)，” Kris Maxwell, a sales employee at GHH said.“For example, certain plants need certain nutrients and pH levels.But don’t worry.You can change the hydroponic solution(溶液) by adding or taking away nutrients, or by changing the pH level, or even by controlling the amount of a water in solution, so that plants get all the nutrients and water requirements they need.There are even different solutions for certain stages in the plant’s growth.”
In this indoor environment, LED lights, which are environmentally friendly, take the place of the sun.Heaters, coolers, and special machines control the temperature and humidity(湿度)．Up to 300 plants can grow in one container unit.
GHH also sells aeroponic systems.With this system, plants are placed in huge containers
where only the roots are put in a solution.Nutrient-rich wastes from fish, for example, are filtered(过滤) and sent through the system.
“The good thing about this method is that no fertilizers have to be used because the fish produce all of the necessary nutrients，” Maxwell said.“Another advantage of vertical farming is that no insects or other pests will damage your crops.”
What do you think？Does vertical farming have a bright future？
