A Description of Jambūdvipa

to the northern side of llāvṛta-varṣa for the benefit of those who live there. Because of these flowing rivers, all the people have ample supplies of milk, yogurt, honey, clarified butter [ghee], molasses, food grains, clothes, bedding, sitting places and ornaments. All the objects they desire are sufficiently supplied for their prosperity, and therefore they are very happy.
PURPORT
The prosperity of humanity does not depend on a demoniac civilization that has no culture and no knowledge but has only gigantic skyscrapers and huge automobiles always rushing down the highways. The products of nature are sufficient. When there is a profuse supply of milk, yogurt, honey, food grains, ghee, molasses, dhotis, saris, bedding, sitting places and ornaments, the residents are actually opulent. When a profuse supply of water from the river inundates the land, all these things can be produced, and there will not be scarcity. This all depends, however, on the performance of sacrifice as described in the Vedic literature.
annād bhavanti bhūtāni parjanyād anna-sambhavaḥ yajñād bhavati parjanyo yajñaḥ karma-samudbhavaḥ
“All living bodies subsist on food grains, which are produced from rains. Rains are produced by performance of  yajña  [sacrifice], and  yajña  is born of prescribed duties.” These are the prescriptions given in  Bhagavad-gītā  (3.14). If people follow these principles in full  Kṛṣṇa  consciousness, human society will be prosperous, and they will be happy both in this life and in the next.
