Vertical(@E E ÉJ)farming is a hugely promising agricultural  technique that aims to produce more food to meet the growing population on our planet.The technique includes growing in vertical frames or even in high-rise farms,saving on precious ground space,while moving farms into urban areas,creating vertical farming "towers' in buildings and producing nutritious crops without topsoil.

Climate change is affected by traditional and intensive(EZ # ÉJ)farming practices.Traditional farming needs a lot of space to tend livestock and rich soil to grow either food crops or feed for livestock.Typically,that means clearing forest or other wild habitats.But the arrival of vertical farming means that means that much less space can be used to feed more people quickly.

The United Nations estimates that he word's population will hit nearly 10 billion by the year 2050.Almost 70 percent of those people will live in and around cities.Vertical farming allows food production equipment to be built close to population centers rather than in rural areas.There food production can expand upwards rather ' than outwards.The crops raised also travel fewer miles to customers and can be grown fresh in urban surroundings,reducing the amount of per serving .

Growing crops indoors allows farmers to strictly control water,temperature,light conditions and maximize yield.Using colored LED lights allows farmers to aim at blue wavelengths to promote leaf growth and red light to encourage flowing.LED lights are also more efficient and produce less heat than traditional lights so as to cut down on energy wastage. 

Of course,as the vertical farming industry expands,it is worth noting that it has limitations - t,only wonks for some crop and is labor-intensive farming with high yield feeds more people with the same or fewer resources.

What can we infer about vertical farming from the first two paragraphs?（）
