The encyclical letter Laudato Si is available here on the Vatican website. Even for living things that do not possess personhood, there is no right to trample:
82. Yet it would also be mistaken to view other living beings as mere objects subjected to arbitrary human domination. When nature is viewed solely as a source of profit and gain, this has serious consequences for society. This vision of “might is right” has engendered immense inequality, injustice and acts of violence against the majority of humanity, since resources end up in the hands of the first comer or the most powerful: the winner takes all. Completely at odds with this model are the ideals of harmony, justice, fraternity and peace as proposed by Jesus. As he said of the powers of his own age: “You know that the rulers of the Gentiles lord it over them, and their great men exercise authority over them. It shall not be so among you; but whoever would be great among you must be your servant” (Mt 20:25-26).
We indeed know that much of our world’s modus operandi, in any number of philosophies, is geared to victory over competitors and the subjugation of those who can be exploited. Pope Francis suggests this moves totally against the Gospel message.
