Everything is described very nicely in the Bhagavad-gītā. Annād bhavanti bhūtāni. Annād bhavanti bhūtāni parjanyād anna-sambhavaḥ. Parjanyād anna-sambhavaḥ, and yajñād bhavati parjanyo yajñaḥ karma... (BG 3.14). (break) And the animals, as soon as they are fatty and grown up, they are sent to the slaughterhouse. This business is going on. So why there should not be crisis in food grain and crisis in human...? There must be. Because we are not abiding by the orders of the Supreme Lord, and dharma means to abide by the orders of the Supreme Lord... Dharmaṁ tu sākṣād bhagavat-praṇītam (SB 6.3.19). You cannot manufacture dharma: "This is this religion; this is that religion." These are all bogus. Real dharma is sarva-dharmān parityajya mām ekaṁ śaraṇaṁ vraja (BG 18.66). This is dharma. All bogus type of dharma—Hindu religion, Muslim religion, this religion, that religion—they are not dharma.
Therefore it is said here, sa vai puṁsāṁ paro dharmaḥ. Paraḥ means Supreme. What is that? Yato bhaktir adhokṣaje, "Wherein this is taught, 'Just surrender to the Supreme Lord, Kṛṣṇa, that is first-class religion." All other religions, they are bogus. That is not religion. Just like good citizenship means to abide by the laws of the state, of the government. That is good citizenship. Similarly, a real religious person means who is abiding by the orders of the Supreme Lord.
