…And Bhagavad-gītā says, annād bhavanti bhūtāni [Bg. 3.14]. The maintenance of the living entities—bhūtāni means living entities—can be done by production of food grains. Annād bhavanti bhūtāni. Then parjanyād anna-sambhavaḥ. And then it is said, parjanyād anna-sambhavaḥ, yajñād bhavati parjanyo yajñaḥ karma-samudbhavam [Bg. 3.14]. This formula is given in the Bhagavad-gītā, that living entities, it doesn’t matter whether animal or men, they are flourished, they are raised very nicely, provided there is anna. Anna means food grain.So we can produce enough quantity of food grains all over the world. And if we actually produce food grains, we can feed ten times of the population which are at present. But unfortunately, we are not producing food grains. That is the problem. It is not the problem of overpopulation. It is the problem that we are not producing food grains. This is clearly stated, that unless you have sufficient food grains, how you can maintain? They have taken a policy that they would not… Especially in the Western countries, I see that they will not produce food. They will raise some cattles and send them to the slaughterhouse for eating. This policy is going on. And this is not a very good policy. You produce your food grain. 

Below we are showing what we need here to supply much of our food grains requirement per year.
