Rhinos don’t criticize lions for their diet. Why would We? Some critters are vegetarians, some are carnivores, and others scavenge. The point is always the same: What’s for dinner? No dinner, no tomorrow. So simple. Equal opportunity, equal hazard.
No critter decides what to eat. Nature has determined all the options for each critter.
Rhinos are wired to eat greenery only, or fruit on a good day. Beyond that, it’s a “no-thank-you-so-much”. Is there a problem here? Not with Rhinos there isn’t.
