Agricultural Monocultures have been utilized across the world for decades. Monocultures are not often present in nature so many of these crops are not sustainable because they destroy soil and water quality.
..without monocultures could we feed our world?
This problem is becoming so severe, that one day if we do not have arable soil human beings will no longer be able to survive.
Growing monoculture crops destroy soil, water and other important resources much faster than sustainable methods of farming. Projections state that by 2050 the amount of arable soil per person on Earth will be reduced by half. (Video Credit: Food and Agriculture Organization of the United Nations)
