Farms Appear in Cities

Whenyou hear the word “farm”, you may imagine the countryside with cows and crops.But scientists say the farms of the future could be built in tall buildings insome large cities.
　　It may be difficultto believe, but in fact, the technology for growing crops in doors alreadyexists. Farming in the city is already happening. Some vegetables are alreadygrown in greenhouses. Even the scientists at the South Pole research stationcan enjoy fresh vegetables they grow in their own greenhouse.
　　Experts say indoorfarming solves many problems. First, traditional farming takes up a lot ofland. Growing crops in tall buildings — called vertical farming（垂直农业）— can solve the problem.Also, fruits and vegetables grown indoors would not face serious threats frominsects and weather.
　　Though vertical farmsdon’t exist yet, experts have created a plan for recycling in such farms. Thewater from indoor fish ponds would be used to water crops. Gases from cropwaste would be used to heat the building. Waste from chicken or pigs would bereused as a source of energy.
　　But experts believevertical farming is not going to be easy. They say it can be difficult tocontrol climate conditions indoors. Besides, Plants differ in their weather andlighting needs. For example, some plants like warm, sunny weather, but otherplants prefer cooler temperatures.
　　That’s not to saythese difficulties won’t be overcome — but it will take time. Most expertssuggest it may take about 5 to 15 years before the first vertical farms couldbe created.

城市中的农场

当你听到“农场”这个词时，你可能会想到乡村，那里有牛和农作物。但科学家们说，未来的农场可能会建在一些大城市的高楼里。

这可能让人难以置信，但实际上，室内种植技术已经存在。城市里的农业已经在进行中。有些蔬菜已经在温室里种植。甚至南极研究站的科学家们也能享受到自己在温室里种植的新鲜蔬菜。

专家们说，室内农业解决了许多问题。首先，传统农业占用了大量土地。在高楼里种植作物——被称为垂直农业——可以解决这个问题。此外，在室内种植的水果和蔬菜不会受到昆虫和天气的严重威胁。

虽然垂直农场尚未存在，专家们已经为这种农场设计了循环利用的计划。室内鱼塘的水将用于灌溉作物。作物废料产生的气体将用于加热建筑物。鸡或猪的废料将被重新用作能源来源。

但专家们认为，垂直农业不会那么容易。他们说，在室内控制气候条件可能很困难。此外，植物对天气和光照的需求各不相同。例如，有些植物喜欢温暖、阳光充足的天气，而其他植物则更喜欢凉爽的温度。

这并不是说这些困难无法克服——但这需要时间。大多数专家建议可能需要大约5到15年的时间，才能建立起第一个垂直农场。
