It is moral to use other living creatures as resources.

It is immoral to use other creatures to we, humans, advantage. Using other earthlings violate the principle of equality. Speciesism: Discrimination in favor of one species, usually the human species, over another, especially in the exploitation or mistreatment of animals by humans. If a being suffers, there can be no moral justification for refusing to take that suffering into consideration. Racists violate the principle of equality by giving greater weight to the interests of one's own race when there is a clash between their race and the interests of another race. Sexists violate the principle of equality by favoring the interests one one's own sex. Similarly, specieists allow the interests of one's own species to override the greater interests of another's species. In each case, the pattern is identical. In all such cases, humans with power exploit those who lack power. Undoubtedly, there are differences between racism and sexism vs. speciesism because humans and other earthlings are not the same in many respects. But the question of sameness wears another face. Granted, other animals do not have all the same desires we humans have. Granted, they do not comprehend everything we humans comprehend. Nevertheless, we and they do have many of the same desires and do comprehend some of the same things. The desire for food and water, shelter and companionship, freedom of movement and avoidance of pain, both humans and other animals share. As for comprehension, like humans, many non-human animals not only live on earth but understand the world in which they live, otherwise they could not survive. So beneath the many differences there is sameness. Like us, these animals embody the mystery and wonder of consciousness. Like us, they are not only in the world but are also aware of it. Like us, they are psychological centers of life that is uniquely their own. In these fundamental respects, humans stand on all fours so-to-speak. "As often as Herman witnessed the slaughter of animals and fish, he always had the same thought: In their behavior toward creatures, all men were Nazis. The smugness with which man could do with other species as he pleased exemplify the most extreme racist theories. The principle that might is right." - Isaac Bashevis Singer In his book- "The Outermost House"- author Harry Beston wrote, " We need another and wiser, and perhaps more mystical concept of animals. Remote from universal nature...man in civilization serve as the creature through the glass of his knowledge and sees thereby a feather magnified, and the whole image in distortion. We patronize them for their incompleteness. For their tragic fate of having taken form so far below ourselves. And therein we err and greatly err. For the animal shall not me measured by man. In a world older and more complete than ours, they move finished and complete. Gifted with extensions of the senses we have lost or never attained. Living by voices we shall never hear. They are not brethren. They are not underlings. They are other nations, caught with ourselves in the net of life and time. Fellow prisoners of the splendor and travail of the earth." Humans do not have the moral right to use animals as food, clothing, entertainment, or testing because that would violate the principle of equality. If humans can survive without the suffering of other beings, than it is unjustified to use animals to our advantage.
