Erik Kobayashi-Solomon spent a day with Dr. Paul Gauthier, a plant physiologist specializing in vertical farming research and came away with several important ideas about vertical farming.
Humans have 12,000 years of experience growing food, but only a generation or so worth of experience growing crops indoors. We are still progressing up the technology learning curve (学习曲线). What's more, traditional farming techniques are based on conditions that are not applicable to vertical farming. Therefore, without taking time to understand the science, vertical farming is not likely to be able to live up to its implied promises.
The cost of powering LED grow lights is one of the biggest problems a vertical farm must overcome. Dr. Louis Albright at Cornell has characterized vertical farms as " pie-in-the-sky" businesses. He famously calculates, for instance, that the cost of a loaf of bread would be $ 24 if farmed indoors — the cost is too high. Gauthier acknowledges that energy prices are high but points out that scientific work has shown that only about 6% of available sunlight is used in crop photosynthesis (光合作用), so there may be ways of growing the same plants with less light.
Gauthier also points out that while energy costs are a bit high, vertical farming does create high efficiencies in other areas. Water usage may be significantly reduced because the same water can be recycled time and again. Fertilizer use can be greatly reduced and pesticides for pest control are unnecessary. It's clear that vertical farming offers real value to society.
The future is probably mixed. In some environments — the Middle East, for instance — a move to vertical farming is a no-brainer. An indoor farm in Saudi Arabia, for instance, can use solar energy to power LEDs at low cost without shading out other farmland. In other geographies, though, the expense of establishing a facility places a high bar on growth and profitability. A large vertical fanning and equipment operation only started generating a small profit eight years into its nine-year life.
1.What can we infer about vertical farming in Paragraph 2?
A.It will replace traditional farming one day.
B.It relies on research of more basic science.
C.It can be applicable on different conditions.
D.It actually came into being 12,000 years ago.
2.What does Dr. Albright think of vertical farms?
A.They use less light than traditional ones.
B.They may seem very unlikely to succeed.
C.They can overcome many problems in farming.
D.They do not need any natural sunlight any longer.
3.What is the fourth paragraph mainly about?
A.The ways of reducing costs of vertical fanning.
B.The secrets of developing vertical farming.
C.The recent trend of vertical farming.
D.The benefits of vertical farming.
4.Why is the example of “an indoor farm in Saudi Arabia” mentioned?
A.To show vertical fanning can work well in some places.
B.To prove solar energy is vital for farming in Saudi Arabia.
C.To confirm the expense of setting up a vertical farm is high.
D.To argue vegetables do not need to be imported any longer.

Erik Weihenmayer was born with an eye disorder. As a child his eyesight became worse and then, at the age of 13, he lost his sight completely. However, he did not lost his determination to lead a full and active life.
Erik became an adventurer. He took up parachuting, wrestling and diving. He competed in long-distance biking, marathons and skiing. His favorite sport, though, is mountaineering.
As a young man, Erik started to climb mountains. He reached the summit of Mount McKinley in 1995 and then climbed the dangerous 1000-meter rock wall of EI Capitan. Two years later, while climbing Mount Kilimanjaro in Kenya with his girlfriend, they stopped for a time at 13, 000 feet above sea level---in order to get married. In 1999, he climbed Aconcagua, the tallest mountain in South America. And then, on May25, 2001, at the age of 33, Erik successfully completed the greatest mountaineering challenge of all. He climbed Mount Everest, the highest mountain in the world.
Erik invented his own method for climbing mountains. He carries two long poles, one to lean on and the other to test the way ahead of him. The climber in front of him wears a bell to guide him. Erik is a good team member. He does his share of the job, such as setting up tents and building snow walls.
Although he could not enjoy the view, Erik felt the excitement of being on the summit of Everest. He hopes that his success will change how people think about the blind. “When people think about a blind person or blindness, now they will think about a person standing on top of the world.”
