Vishnupurana 6.1.p7

6.1.p7

O Maitreya, in the Kali age corrupted by unbelievers, men will refrain from adoring Vishnu, the lord of sacrifice and the creator and sovereign of all and will say "Of what authority are the Vedas? What are the celestials or Brahmanas? What need there is of purification with water?" At the approach of the Kali, O Vipra, the clouds will yield scanty rain; the corn will be light in ear and the grain will be poor and of little sap: garments will be mostly made of the fibres of the San: the principal of trees will be the Sami; principle caste will be the Sudra; millet will be the more common grain; the milk in use will be chiefly that of goats; unguents will be made of Ushira grass. The mother and father-in-law will be venerated in the place of parents; and a man's friend will be his brother-in-law or one who has a wanton wife. Men will say "Who has a father? Who has a mother? Every one is born according to his deeds"; therefore they will regard the wife's or the husband's parents as their own. Gifted with little sense they will be subject to all sorts of infirmities of mind, speech and body and will daily commit sins; and every thing that is likely to afflict beings, vicious, impure and wretched will be generated in the Kali Yuga. Thus, O Brahman, when holy study, oblations to fire and convocations of the celestials shall be stopped some few people shall live at a holy place. And at this place with the least trouble that piety shall be accumulated which could be acquired with the greatest exertions in the Krita age.
