The vaiśyas, the members of the mercantile communities, are especially advised to protect the cows. Cow protection means increasing the milk productions, namely curd and butter. Agriculture and distribution of the foodstuff are the primary duties of the mercantile community backed by education in Vedic knowledge and trained to give in charity. As the kṣatriyas were given charge of the protection of the citizens, vaiśyas were given the charge of the protection of animals. Animals are never meant to be killed. Killing of animals is a symptom of barbarian society. For a human being, agricultural produce, fruits and milk are sufficient and compatible foodstuffs. The human society should give more attention to animal protection.

The principal sign of the age of Kali is that lower-caste śūdras, i.e., men without brahminical culture and spiritual initiation, will be dressed like administrators or kings, and the principal business of such non-kṣatriya rulers will be to kill the innocent animals, especially the cows and the bulls, who shall be unprotected by their masters, the bona fide vaiśyas, the mercantile community. In the Bhagavad-gītā (18.44), it is said that the vaiśyas are meant to deal in agriculture, cow protection and trade. In the age of Kali, the degraded vaiśyas, the mercantile men, are engaged in supplying cows to slaughterhouses. The kṣatriyas are meant to protect the citizens of the state, whereas the vaiśyas are meant to protect the cows and bulls and utilize them to produce grains and milk. The cow is meant to deliver milk, and the bull is meant to produce grains. But in the age of Kali, the śūdra class of men are in the posts of administrators, and the cows and bulls, or the mothers and the fathers, unprotected by the vaiśyas, are subjected to the slaughterhouses organized by the śūdra administrators.

When there is a scarcity of grain, the government should follow the methods prescribed in the śāstra and approved by the ācāryas; thus there will be a sufficient production of grains, and food scarcity and famine can be checked. Bhagavad-gītā recommends that we perform yajña, sacrifices. By the performance of yajña, sufficient clouds gather in the sky, and when there are sufficient clouds, there is also sufficient rainfall. In this way agricultural matters are taken care of. When there is sufficient grain production, the general populace eats the grains, and animals like cows, goats and other domestic animals eat the grasses and grains also. According to this arrangement, human beings should perform the sacrifices recommended in the śāstras, and if they do so there will no longer be food scarcity. In Kali-yuga, the only sacrifice recommended is saṅkīrtana-yajña.

When the government neglects agriculture, which is necessary for the production of food, the land becomes covered with unnecessary trees. Of course, many trees are useful because they produce fruits and flowers, but many other trees are unnecessary. They could be used as fuel and the land cleared and used for agriculture. When the government is negligent, less grain is produced. As stated in Bhagavad-gītā (18.44), kṛṣi-go-rakṣya-vāṇijyaṁ vaiśya-karma svabhāva jam: the proper engagements for vaiśyas, according to their nature, are to farm and to protect cows. The duty of the government and the kṣatriyas is to see that the members of the third class, the vaiśyas, who are neither brāhmaṇas nor kṣatriyas, are thus properly engaged. Kṣatriyas are meant to protect human beings, whereas vaiśyas are meant to protect useful animals, especially cows.

A sannyāsī is allowed to beg from door to door, but a gṛhastha cannot do so. Gṛhasthas may earn their living according to the four divisions of spiritual life. A brāhmaṇa gṛhastha may earn his livelihood by becoming a learned scholar and teaching people in general how to worship the Supreme Personality of Godhead. He may also assume the duty of worship himself. Therefore it is said that only brāhmaṇas may engage in Deity worship, and they may accept as prasāda whatever people offer the Deity. Although a brāhmaṇa may sometimes accept charity, it is not for his personal maintenance but for the worship of the Deity. Thus a brāhmaṇa does not stock anything for his future use. Similarly, kṣatriyas may collect taxes from the citizens, and they must also protect the citizens, enforce rules and regulations, and maintain law and order. Vaiśyas should earn their livelihood through agriculture and cow protection, and śūdras should maintain their livelihood by serving the three higher classes. Unless one becomes a brāhmaṇa, one cannot take sannyāsa. Sannyāsīs and brahmacārīs may beg alms door to door, but a gṛhastha cannot.
(SRIMAD BHAGAVATAM------6:5:36------PURPORT).

When we consider the past condition of the agriculturalist in the village, we can see how opulent he was, simply because of agricultural produce and protection of cows. At the present, however, agriculture having been neglected and cow protection given up, the agriculturalist is suffering pitiably and is dressed in a niggardly torn cloth. This is the distinction between the India of history and the India of the present day. By the atrocious activities of ugra-karma, how we are killing the opportunity of human civilization!
