Growing Up
According to UN
statistics, by the year 2050, the population of planet Earth will have risen to
over 9 billion and feeding all these people will require extra farmland the
size of Brazil. The scientists offer the idea of vertical farming.
Vertical farms are a
good idea because they don`t take up as much space as traditional farms. That
is why, they may be a solution to growing enough food for an increasing
population with a lack of farmland. They can be built in cities to allow people
to have access to local produce and therefore reduce transport costs. This idea
is also environmentally friendly as the farmswill be powered by solar, wind
energy and will grow a variety of fruit and vegetables in a solution of
nutrients and water. The walls will be made of glass to allow in sunlight. The
scientists point out that just one 30-storey building would provide food for
10 000 people.
However, the idea
isn`t without its problems. Crops nearer the glass would get more light. That
means they would grow quicker than crops farther away. Possible solutions
include having a permanent light source on every floor like the ones we now
have in industrial greenhouses.
All in all, mankind
remembers the stories of The Hanging Gardens of Babylon. There were the structures
with lush green gardens on different levels many metres high. These are long
gone, but the situation in our modern consumer society isn`t good enough. The
population rises and food prices soar. So,it`s a good
idea to let a modern-day equivalent of these gardens spring up.
