“The prosperity of humanity does not depend on a demoniac civilization that has no culture and no knowledge but has only gigantic skyscrapers, and huge automobiles always rushing down the highways. The products of nature are sufficient” (Srimad-Bhagavatam5.16.24).
“If there is enough milk, enough grains, enough fruit, enough cotton, enough silk, and enough jewels, then why do the people need cinemas, houses of prostitution, slaughterhouses, etc.? What is the need of an artificial luxurious life of cinema, cars, radio, flesh, and hotels?” (Srimad-Bhag. 1.10.4).
“Advancement of civilization is estimated not on the growth of mills and factories to deteriorate the finer instincts of the human being, but on developing the potent spiritual instincts of human beings and giving them a chance to go back to Godhead” (Srimad-Bhag. 1.11.12).
On Cow Protection
“Krishna advises go-raksya, the protection of cows. This is essential, because if cows are cared for properly they will surely supply sufficient milk. We have practical experience in America that in our various ISKCON farms we are giving proper protection to the cows and receiving more than enough milk. In other farms the cows do not deliver as much milk as in our farms; because our cows know very well that we are not going to kill them, they are happy, and they give ample milk” (Srimad-Bhag. 9.15.25).
“… they are killing cows in the thousands. Therefore they are unfortunate in spiritual consciousness, and nature disturbs them in so many ways, especially through incurable diseases like cancer and through frequent wars… among nations. As long as human society continues to allow cows to be regularly killed in slaughterhouses, there cannot be any question of peace and prosperity” (Srimad-Bhag. 8.8.11).
On the Distribution of Grains
“… the earth produces sufficient grain to feed the entire population, hut the distribution of this grain is restricted due to trade regulations and a desire for profit. Consequently in some places there is a scarcity of grain and in others profuse production. If there were one [Krishna conscious] government on the surface of the earth to handle the distribution of grain, there would be no question of scarcity, no necessity to open slaughterhouses, and no need to present false theories about overpopulation” (Srimad-Bhag. 4.17.25).
On the Need for Sacrifice to God
“One is mistaken if he thinks that by applying modern machines such as tractors, grains can be produced. If one goes to a desert and uses a tractor, there is still no possibility of producing grains. We may adopt various means, but it is essential to know that the planet earth will stop producing grains if sacrifices are not performed” (Srimad-Bhag. 4.19.1).
“If sankirtana sacrifice [the congregational chanting of the Hare Krishna mantra] is performed, there will be no difficulty, not even in industrial enterprises. Therefore this system should be introduced in all spheres of life—social, political, industrial, commercial, etc. Then everything will run very peacefully and smoothly” (Srimad-Bhag. 4.19.7).
“Because people are without Krishna consciousness, they have become thieves, and consequently they are being punished by the laws of material nature. No one can check this, not even by introducing so many relief funds and humanitarian institutions. Unless the people of the world take to Krishna consciousness, there will be a scarcity of food and much suffering” (Srimad-Bhag. 4.18.8).
