The modern theory that starvation is due to an increase in population is not accepted.

SB 3.5.49 P     Vidura' s Talks with Maitreya   
   The modern theory that starvation is due to an increase in population is not accepted by the demigods or the devotees of the Lord. The devotees or demigods are fully aware that the Lord can maintain any number of living entities, provided they are conscious of how to eat. If they want to eat like ordinary animals, who have no God consciousness, then they must live in starvation, poverty and want, like the jungle animals in the forest. The jungle animals are also maintained by the Lord with their respective foodstuffs, but they are not advanced in God consciousness. Similarly, human beings are provided with food grains, vegetables, fruits and milk by the grace of the Lord, but it is the duty of human beings to acknowledge the mercy of the Lord. As a matter of gratitude, they should feel obliged to the Lord for their supply of foodstuff, and they must first offer Him food in sacrifice and then partake of the remnants.
