I find the caption generative, meaning that it could be elaborated but that I appreciate that it prompts questions without too much elaboration. I don't think it's necessary to add more.
It would be helpful if the author incorporates the notion of toxic places a bit more in their caption. Presently, the caption ends on a rather sudden note and does not quite conclude (and it is unclear how the number of cattle feeds into the argument). A little more theorization may also help to identify the ethnographic message, perhaps by concluding the caption with a tie-in back to the concepts in the second paragraph.
