There is no question of overpopulation. This is a false theory. If God can create, He can maintain also. And actually, this is the fact. I am traveling all over the world. There are so much vacant places upon the surface of the globe that, that ten times more than the present population can be easily maintained. But we, we, we do not know how to use it. In Africa, in Australia, in your America, enough land still lying. But because we have encroached upon the land of Kṛṣṇa, the difficulty's there. China is overpopulated. India is overpopulated. But we, if we take to Kṛṣṇa consciousness, these difficulties will be over within a second.
Kṛṣṇa consciousness means to take everything Kṛṣṇa's. I am also Kṛṣṇa's. That is Kṛṣṇa consciousness. Actually, that is the fact. Everything... Kṛṣṇa means God. Everything belongs to God. I also belong to God. Īśāvāsyam idaṁ sarvam (ISO mantra 1). Everything belongs to God. That's a fact. But we do not accept the fact. We take something illusory. Therefore, it is called māyā.
Just like the Americans. They are claiming this land is for the American group. Similarly, other nations, they're... but the land actually belongs to God. The land, the sky, the water, and the products in the land, in the sky, in the water, everything belongs to God. And we are children of God. We have got the right to live at the expense of father. Just like we live, small children. They live at the cost of father. Similarly, we also live by the arrangement of God. Why should we claim that this is our property?
This is the idea of spiritual communism. In Bhāgavata these things are stated, how to feel spiritual communism. In the spiritual communism... The present communists, they are thinking of the human being only. And the animals are being sent to the slaughterhouse. Although the human being and the animal is born in the same land... Actually, they are also nationals. National means one who's born in that particular land. So why not these animals, nationals? But because they have no Kṛṣṇa consciousness, they cannot think so broadly. They think nationalism means it is limited to the human being, not to the animals, not to the trees.
But when you become Kṛṣṇa conscious you understand that the trees, the plants, the reptiles, the aquatics, the human beings, the beasts, everyone, each and everyone, part and parcel of God. According to their karma, they have got different bodies, the color, as I explained. According to kāraṇam guṇa-sango 'sya sad-asad-janma-yoniṣu (BG 13.22). These things are described in the Bhagavad-gītā. One has got a different type of body according to his karma. Karmaṇā daiva netreṇa jantor deha upapattaye (SB 3.31.1). By karma we create next body.
So this is a great science. People do not know how things are taking place, how there are so many species of life, how one is so-called happy, one so-called distressed. Why one is rich, one is poor. Why there are so many planets? Why some of them are demigods and some of them are human beings, some of them are animals? It is a great science, but there is no cultivation of this knowledge in the modern universities or educational institutions. Perhaps we are the only group of men, we are trying to propagate this science of Kṛṣṇa consciousness. But it is a perfect science to understand the position.
