In Kali-yuga, people are extremely liberal, but mixing with women and talking with them as equals actually constitutes an uncivilized way of life.
(Srimad Bhagavatam-----7:12:8-----purport).

In this age of Kali, practically everyone is a śūdra (kalau śūdra-sambhavāḥ), and finding anyone who is a brāhmaṇa, kṣatriya or vaiśya is very difficult.
(Srimad Bhagavatam-----7:11:18-20-----purport).

Especially in this age, Kali-yuga, great leaders, politicians, philosophers and scientists are all engaged in foolish activities, thinking, "This is mine, and this is yours."
(Srimad Bhagavatam-----7:6:16-----purport).

Because the government in Kali-yuga is full of demons, the living conditions of devotees are always disturbed.
(Srimad Bhagavatam-----7:8:42-----purport).

Especially in this age of Kali-yuga, it is said that instead of protecting the money of the citizens, the government itself will take away the money with the force of law.
(Srimad Bhagavatam-----7:13:36-----purport).

In Kali-yuga, the available quantity of food grains and ghee is gradually diminishing, and people are embarrassed that they cannot produce sufficient ghee and food grains.
(Srimad Bhagavatam-----7:14:17-----purport).

In Kali-yuga there is a scarcity of food almost every year, and thus philanthropists spend lavishly to feed the poor.
(Srimad Bhagavatam-----7:15:6-----purport).

Especially in this Kali-yuga, material advancement means degradation and attraction to many unwanted necessities that create a low mentality.
(Srimad Bhagavatam-----7:15:29-----purport).

Kali-yuga is full of contamination. This is described in the Śrīmad-Bhāgavatam (12.3.51):
kaler doṣa-nidhe rājann
asti hy eko mahān guṇaḥ
kīrtanād eva kṛṣṇasya
mukta-saṅgaḥ paraṁ vrajet
This age of Kali is full of unlimited faults. Indeed, it is just like an ocean of faults (doṣa-nidhi). But there is one chance, one opportunity. Kīrtanād eva kṛṣṇasya mukta-saṅgaḥ paraṁ vrajet: simply by chanting the Hare Kṛṣṇa mantra, one can be freed from the contamination of Kali-yuga and, in his original spiritual body, can return home, back to Godhead. This is the opportunity of Kali-yuga.
(Srimad Bhagavatam-----8:5:23-----purport).

From Satya-yuga to Kali-yuga, the principles of religion and occupational duty gradually deteriorate. In Satya-yuga, the religious principles are observed in full, without deviation. In Tretā-yuga, however, these principles are somewhat neglected, and only three fourths of the religious duties continue. In Dvāpara-yuga only half of the religious principles continue, and in Kali-yuga only one fourth of the religious principles, which gradually disappear. At the end of Kali-yuga, the principles of religion, or the occupational duties of humanity, are almost lost. Indeed, in this Kali-yuga we have passed through only five thousand years, yet the decline of sanātana-dharma is very prominent. The duty of saintly persons, therefore, is to take up seriously the cause of sanātana-dharma and try to reestablish it for the benefit of the entire human society. The Kṛṣṇa consciousness movement has been started according to this principle. As stated in Śrīmad-Bhāgavatam (12.3.51):
kaler doṣa-nidhe rājan
asti hy eko mahān guṇaḥ
kīrtanād eva kṛṣṇasya
mukta-saṅgaḥ paraṁ vrajet
The entire Kali-yuga is full of faults. It is like an unlimited ocean of faults. But the Kṛṣṇa consciousness movement is very authorized. Therefore, following in the footsteps of Śrī Caitanya Mahāprabhu, who five hundred years ago inaugurated the movement of saṅkīrtana, kṛṣṇa-kīrtana, we are trying to introduce this movement, according to superior orders, all over the world.
(Srimad Bhagavatam-----8:14:4-----purport).

In the present age, Kali-yuga, the number of such shameless men, who are agnostics disbelieving in the existence of God, has increased. Trying to defy the authority of the Supreme Personality of Godhead, so-called scientists, philosophers and politicians manufacture plans and schemes for the destruction of the world. They cannot do anything good for the world, and unfortunately, because of Kali-yuga, they have plunged the affairs of the world into mismanagement.
(Srimad Bhagavatam-----8:22:20-----purport).

Rākṣasas are understood to be accustomed to eating their own sons, as snakes and many other animals sometimes do. At the present moment in Kali-yuga, Rākṣasa fathers and mothers are killing their own children in the womb, and some are even eating the fetus with great relish. Thus the so-called civilization is gradually advancing by producing Rākṣasas.
(Srimad Bhagavatam-----10:4:15-----purport).

Especially in this age, Kali-yuga, cows are being killed all over the world, and as soon as there is a movement to establish brahminical civilization, people in general rebel.
(Srimad Bhagavatam-----10:4:41-----purport).

In Kali-yuga, wealth alone will be considered the sign of a man's good birth, proper behavior and fine qualities. And law and justice will be applied only on the basis of one's power.
(Srimad Bhagavatam-----12:2:2-----translation).

In the Kali age people tend to be greedy, ill-behaved and merciless, and they fight one another without good reason. Unfortunate and obsessed with material desires, the people of Kali-yuga are almost all śūdras and barbarians.
(Srimad Bhagavatam-----12:3:25-----translation).

Because of the bad qualities of the age of Kali, human beings will become shortsighted, unfortunate, gluttonous, lustful and poverty-stricken. The women, becoming unchaste, will freely wander from one man to the next.
(Srimad Bhagavatam-----12:3:31-----translation).

In Kali-yuga men will be wretched and controlled by women. They will reject their fathers, brothers, other relatives and friends and will instead associate with the sisters and brothers of their wives. Thus their conception of friendship will be based exclusively on sexual ties.
(Srimad Bhagavatam-----12:3:37-----translation).

In the age of Kali, people's minds will always be agitated. They will become emaciated by famine and taxation, my dear King, and will always be disturbed by fear of drought. They will lack adequate clothing, food and drink, will be unable to properly rest, have sex or bathe themselves, and will have no ornaments to decorate their bodies. In fact, the people of Kali-yuga will gradually come to appear like ghostly, haunted creatures.
(Srimad Bhagavatam-----12:3:39-40-----translation).

In Kali-yuga men will develop hatred for each other even over a few coins. Giving up all friendly relations, they will be ready to lose their own lives and kill even their own relatives.
(Srimad Bhagavatam-----12:3:41-----translation).

O King, in the age of Kali people's intelligence will be diverted by atheism, and they will almost never offer sacrifice to the Supreme Personality of Godhead, who is the supreme spiritual master of the universe. Although the great personalities who control the three worlds all bow down to the lotus feet of the Supreme Lord, the petty and miserable human beings of this age will not do so.
(Srimad Bhagavatam-----12:3:43-----translation).

Terrified, about to die, a man collapses on his bed. Although his voice is faltering and he is hardly conscious of what he is saying, if he utters the holy name of the Supreme Lord he can be freed from the reaction of his fruitive work and achieve the supreme destination. But still people in the age of Kali will not worship the Supreme Lord.
(Srimad Bhagavatam-----12:3:44-----translation).

In the Kali-yuga, objects, places and even individual personalities are all polluted. The almighty Personality of Godhead, however, can remove all such contamination from the life of one who fixes the Lord within his mind.
(Srimad Bhagavatam-----12:3:45-----translation).

My dear King, although Kali-yuga is an ocean of faults, there is still one good quality about this age: Simply by chanting the Hare Kṛṣṇa mahā-mantra, one can become free from material bondage and be promoted to the transcendental kingdom.
(Srimad Bhagavatam-----12:3:51-----translation).

Whatever result was obtained in Satya-yuga by meditating on Viṣṇu, in Tretā-yuga by performing sacrifices, and in Dvāpara-yuga by serving the Lord's lotus feet can be obtained in Kali-yuga simply by chanting the Hare Kṛṣṇa mahā-mantra.
(Srimad Bhagavatam-----12:3:52-----translation).
