Heart trouble. And the next death rate is by overeating. So there cannot be any rivalry. Kṛṣṇa, the Supreme Person, nityo nityānām... We are all persons. Just like you consider me, I am the head of your society, similarly, there are so many heads, another head. Brahmā is head. There are so many Brahmās. Then, above them, there is Mahā-Viṣṇu, head. In this way, if you analyze, you'll go to Kṛṣṇa, īśvaraḥ paramaḥ kṛṣṇaḥ (Bs. 5.1), the Supreme Personality of Godhead.
So He has provided everyone's food. There is no problem. It is mistake to accept it that "Because there is overpopulation in the world, there is problem." Just now like we were walking on the St. James Park, the swan, ducks, they are producing one dozen children at a time. And that is also twice, thrice in a year. So they have no problem. Where is the problem of overpopulation? They are not starving. Unless you go and capture them and kill them, they are not dying. You see from the birds, animals—nobody dies of starvation. Eko bahūnāṁ vidadhāti kāmān. Kṛṣṇa is there. He is supplying food for everyone.
