If people become Kṛṣṇa conscious or God conscious, by the transcendental will of the Supreme Personality of Godhead there will be enough foodstuffs produced so that people will have no economic problems at all. One can very easily understand this fact. The production of fruits and flowers depends not upon our will but the supreme will of the Personality of Godhead. If He is pleased, He can supply enough fruits, flowers, etc., but if people are atheistic and godless, nature, by His will, restricts the supply of food. For example, in several provinces in India, especially Maharashtra, Uttar Pradesh and other adjoining states, there is sometimes a great scarcity of foodstuffs due to lack of rainfall. So-called scientists and economists cannot do anything about this. Therefore, to solve all problems, one must seek the good will of the Supreme Personality of Godhead by becoming Kṛṣṇa conscious and worshiping Him regularly in devotional service.
