The Symptoms of Kali-yuga (SBhagavatam 12.2.10-16)

The citizens will suffer greatly from cold, wind, heat, rain, and snow. They will be further tormented by quarrels, hunger, thirst, disease, and severe anxiety.

The maximum duration of life for human beings in Kali-yuga will become less than a hundred years.

By the time the age of Kali ends, the bodies of all creatures will be greatly reduced in size, and the religious principles of followers of varṇāśrama will be ruined. The path of the Vedas will be completely forgotten in human society, and the so-called religion will be mostly atheistic. The kings will mostly be thieves, the occupations of men will be stealing, lying, and needless violence, and all the social classes will be reduced to the lowest level of śūdras. Cows will be like goats, spiritual hermitages will be no different from mundane houses, and family ties will extend no further than the immediate bonds of marriage. Most plants and herbs will be tiny, and all trees will appear like dwarf śamī trees. Clouds will be full of lightning, homes will be devoid of piety, and all human beings will have become like asses. At that time, the Supreme Personality of Godhead will appear on the earth. Acting with the power of pure spiritual goodness, He will rescue eternal religion
