Final answer:
Option D is not a valid reason for Jackson's view of the conservation hunt as heroic because it focuses on fulfilling the desires of poachers and hunters, rather than conservation efforts, which are the main goal of such programs.
Step-by-step explanation:
The reason why Jackson describes the conservation hunt as a hero in the hunting community that is NOT valid is D. 'The hunt will allow poachers and hunters to fulfill their desires within the constraints of the law.' This option implies catering to the desires of poachers and hunters rather than focusing on the conservation and protection of endangered species, which is the main goal of these conservation efforts. Valid reasons are A, B, and C which align with conservation objectives: A. raising money for rhino protection, B. removing problematic individuals from the rhino population that may cause harm, and C. improving reproductive rates among rhinos leading to increased population resilience.
