Based on the draft of the essay, the student's focus is primarily on the challenges elephants face, particularly related to poaching and habitat loss. Given this context, an effective article to complement the essay would be:
an article about what has been done to stop poaching in Africa and Asia
This article would provide valuable insight into the ongoing efforts to combat poaching, which the essay emphasizes as a critical issue. It would also align well with the call to action mentioned in the essay regarding the need for enhanced law enforcement and protection for elephants.
