Vertical Farming is the Future of Agriculture
Agriculture is what made us move from hunter-gatherers to civilised humans. The Agricultural Revolution gave birth to cities, to empires, to states and to governments.
Throughout the ages, agriculture has evolved. During the industrial revolution, people could plant crops and rear animals with more efficiency. The scientific revolutions gave us pesticides and GMOs.
But one thing which didn't change during all these years is Land. We still need land to plant. Actually a plant doesn't require soil to grow. It needs Carbon Dioxide, Water, nutrients and light. One way to make farming more efficient is building vertical farms, that is , indoor farming or hydroponic farming.
Vertical farming will also help fight climate change if it is integrated with renewable energies, it will help fight overpopulation since less land will be needed for farming.
