On many occasions Srila Prabhupada said that the word could easily feed its present population, even if it were ten times larger. For example: “My Guru Maharaja used to say that ‘I don’t find any scarcity within this world, except Krsna consciousness.’ There is no scarcity all over the world. In India there may be scarcity, but outside India still there are so much vacant places, especially in Africa, in America, in Australia, in New Zealand, that ten times of the population of the whole world can be fed. Still. There is so much potency of producing food grains, milk, and other things. Profusely. In America, they throw away so many grains and vegetables daily. It is simply mismanagement. Otherwise, there is no question of scarcity or poverty. There is no question. It is simply propaganda. Because they cannot manage, the foolish people, they present the population has increased and the foodstuff is not properly supplied.” (21 October, 1962, Vrndavana, India).
The only scarcity is Krishna consciousness
