Human population has surpassed seven billion today. With many experts expecting that number to rise above nine billion by 2050. The question of how we are to provide for this many people is becoming a serious issue. More than a billion people today are not getting their basic needs met. Food systems are already struggling to produce enough food as it is. With the world markets operating under a growth economy, this rise in population will inevitably increase waste and consumption of every possible resource, further hampering our ability to bring about a sustainable way of life on Earth.
