A
Everyone knows that the population of the world is the largest ever. As more and more people are born and grow to an older average age than previous generations, everyone on the earth has a responsibility to feed this ever-growing population.
One possible solution to this is vertical (垂直的) farming. While humans have farmed and worked the land as long as history has recorded events, how much humans’ farming has changed! From hands to ancient tools to animals to advanced machinery, the agricultural scenes have changed greatly over the centuries.
Now new and improved farming methods have been considered and studied to keep up with demand. With vertical farming, food is grown vertically by using existing buildings or shipping containers.
Unlike traditional farming that relies on Mother Nature, vertical farming often relies on CEA technology, also known as Controlled Environment Agriculture. With this approach, humans affect light, temperature, gases and more, thus controlling the environment in which plants grow.
The technology used in vertical farming is just expanding into greenhouses, where light and temperature are man-controlled. The final goal of vertical farming is to produce the most possible crops with the least possible space.
Vertical farming has many advantages. There are some other benefits as well.
With more and more humans living in heavily populated areas, vertical farming allows humans to be prepared for the future with continued population growth and increased movements to cities.
In vertical farming, since the environment in which plants grow is controlled by humans, farming can happen all the year round and is not dependent on seasons and weather. It can possibly use 95% less water than traditional farming. Besides, it is easier to produce organic crops in such a controlled environment, and farm chemicals will not be needed to protect the plants. This means less pollution in the environment.
