Srimad Bhagavatam Canto 10, Chapter 05, Text 26

SB 10.5.26

kaccit pasavyam nirujam
bhury-ambu-trna-virudham
brhad vanam tad adhuna
yatrasse tvam suhrd-vrtah
 
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
My dear friend Nanda Maharaja, in the place where you are living with your friends, is the forest favorable for the animals, the cows? I hope there is no disease or inconvenience. The place must be full of water, grass and other plants.
 
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada: 
 
For human happiness, one must care for the animals, especially the cows. Vasudeva therefore inquired whether there was a good arrangement for the animals where Nanda Maharaja lived. For the proper pursuit of human happiness, there must be arrangements for the protection of cows. This means that there must be forests and adequate pasturing grounds full of grass and water. If the animals are happy, there will be an ample supply of milk, from which human beings will benefit by deriving many milk products with which to live happily. As enjoined in Bhagavad-gita (18.44), krsi-go-raksya-vanijyam vaisya-karma-svabhavajam. Without giving proper facilities to the animals, how can human society be happy? That people are raising cattle to send to the slaughterhouse is a great sin. By this demoniac enterprise, people are ruining their chance for a truly human life. Because they are not giving any importance to the instructions of Krsna, the advancement of their so-called civilization resembles the crazy efforts of men in a lunatic asylum.
