National [citizen] means a living entity born in particular country. So at the present moment, the national means only human being. The animals are not nationals. They are being sent to the slaughterhouse. So this kind of sinful activities are going on. Therefore renunciation means to give up these sinful activities. That is real renunciation. Otherwise, you cannot renounce anything. You have to live. And that is allowed at the cost of God. Everything belongs to God. You are son of God.
