I think the problem is how we keep the cattle.
In natural environment, they cohabitant with other animals. They migrates.
When we farm them, we remove anything not our primary product.

In places like Ireland, where cows have existed for 6000 years, they're also part of the ecology by any meaningful metric. There are a lot of more recently arrived species considered native! Mice, hedgehogs, rabbits, and red deer all came later.
This is how cattle is kept in the US: https://www.hcn.org/wp-content/uploads/2025/04/sucked-dry-th...
I'd love to read your definition of "natural ecosystems", is it something like "a system in nature", with "nature" meaning "on planet earth"?
