It be considered immoral to ignore the scientific/ecological reasons not to kill certain animals, no?

Take veganism/vegetarianism for example. I see that as both a moral and scientific issue. Many vegans consider it morally wrong to kill animals for their resources, and make that the basis of their reasoning, but industrialized farming is incredibly damaging to the planet so I can easily see both moral and scientific reasons not to contribute to that. “Scientific” being that it is contributing to climate change and environmental damage, moral being that by contributing, you are helping with the demise of ecosystems and animal and human life in the long term.
