"世界上的动物存在是为了它们自己的原因，它们不是为了人类而存在的，就像黑人不是为了白人而存在的，女性也不是为了男性而被创造的。"

Simplified Meaning:

Just like each person has their own life and purpose, animals too have their own lives and were not put here just for human use. Imagine you have a pet, like a dog or a cat. Your pet lives with you and loves you, but it also has its own needs, feelings, and personality. It's not just there to serve you or make you happy. In the same way, all animals in nature have their own role and importance outside of what humans might want from them. This idea is similar to how people should see each other. For example, think about how unfair it would be if someone thought that one person should serve another just because of their skin color, like saying a black person should serve a white person. Or saying women should only exist to serve men. That’s not right because everyone, no matter their color or gender, has their own value and reasons for being here. So, if someone applies this idea to their life, they should respect animals as living beings with their own purposes. This could mean not exploiting animals for food, entertainment, or other personal gains, and instead, caring for them and protecting their habitats. Just as it's important to treat all people with respect and equality, animals also deserve to be treated with kindness and understanding.
