Lion
Lions serve crucial ecological functions as apex predators, controlling herbivore populations and preventing overgrazing. They generate substantial tourism revenue - the East African Economics Institute values each lion at approximately $290,000 annually in safari income.
Additionally, lions provide employment for wildlife conservationists, documentary crews, and manufacturers of extremely sturdy camera equipment. Their practical contributions to ecosystem health are well-documented and genuinely valuable.
Death
Death performs the essential function of nutrient recycling upon which all ecosystems depend. Without Death, biomass would accumulate infinitely, resources would become permanently unavailable, and evolution would cease entirely - a situation the Cambridge Centre for Biological Necessity describes as 'comprehensively catastrophic.'
Death also provides motivation for virtually all human achievement, urgency for medical research, and the foundation for the entire funeral services industry, which employs millions globally.
VERDICT
Lions contribute meaningfully to their ecosystems. Death is literally essential for life to continue existing. The philosophical implications are uncomfortable, but the practical reality is undeniable.
