It is true. One of the noteworthy consequences is that animals can be shipped in open containers in -30C weather with no food or water. If they arrive all frozen to death, it's not a crime. There isn't even a fine. And so of course this is exactly what happens, and they do die.
When you create a child, whether you fuck it into existence, or whether you engage a surrogate to do it for you, it creates moral responsibilities between you and that child. We all acknowledge this.
The animals we create are morally equivalent to our own children. They are owed the exact same unconditional love and protection.
Aside from the veganism/ antiveganism circlejerks, aren't animals that are raised in a more healthy way more tasty? And aren't injured and dead animals not consumed, therefore wasted and contributing to emissions despite not returning nutritional value?
Scaling down to more humane conditions is good for everybody.
Whether never being born is or is not better than a brief and miserable life is the kind of thing philosophers like to argue about—a question to which there is no generally accepted answer.
"Generally accepted" isn't meaningful in this situation. Slavery is a good example of something that was (and is) generally accepted, but clearly wrong. It is not even generally accepted here today that it is wrong to be needlessly cruel and violent to animals. Whether or not people ACCEPT it, it is obviously wrong. It is morally wrong to cause a sentient being to suffer unnecessarily, especially for our own pleasure. Creating a creature does not give you the moral right to take its life or subject it to harmful conditions, and @Yezzey is exercising philosophical wishful thinking.
