How Urban Farms Are Supposed To Feed Millions of People
Urban farming is supposed to provide people with local food in the metropolitan areas. How ecological the farms really are and promising urban farms worldwide.
Half of the world's 7.5 billion people already live in cities. According to UN calculations, the figure is expected to reach 70 percent by 2050, with an estimated 10 billion people living in the world. Seven billion people in urban conurbations have to be supplied with food from an agriculture that is already reaching its limits today.
The common solution for decades: A well-rehearsed system made of turbo seeds from the laboratory that is cultivated with artificial fertilizers and dozens of pesticides in monocultures.
Biodiversity is lost and resources are wasted if, for example, food is produced for retailers with lots of water in dry areas and food is transported around the world using fossil fuels.
