The bottom line is that the dairy industry causes harm and suffering to animals, including supplementing connected industries like veal and beef,

ok…

which many people justify as a way to minimise waste of necessary byproducts of the dairy industry

conserving resources is good…

while ignoring or overlooking the fact that the dairy industry itself is unnecessary.

I don’t see why that matters. we do have a dairy industry. conserving resources within it is just smart.
