The first step in better treatment for animals is accepting that they are thinking beings and not just food sources.
We have to stop eating them. As long as we consume their bodies, we cannot allow ourselves to believe that they have emotional feelings like fear or affection.
If you think of any animal as a strange form of a human, kept in a pen, never allowed freedom or education, forced to breed, and having family members being killed and their bodies cut up and used for food, it stops being a source of food and becomes a thinking being with feelings. After a while, it becomes quite repulsive to think of eating a dead animal's body parts.
That's true every religion teaches us to be good to the animals and take care of them as much as we can.
We can avoid eating animals but if we are getting enough substitutes. They do have emotional feelings and we should accept that.
That's a good idea I would say, we got to think of it the other way around, but then even plants have a life and we do not really have options there. We can at first stop killing animals for fun and start taking care of them and give them freedom, it will be a long process but it will help
