7 PointsWhy Species of Animals Become Endangered
I. Hunting
A. Animals sought as trophies
B. Animals wanted for commercial purposes
II. Loss of habitat and food
A. Forests
B. Grasslands
C. Poisoning (Insecticides)
Categorical Logic:
• Hunting: Direct predatory actions by humans for recreation (trophies) or commerce (fur/meat/ivory).
• Loss of habitat and food: Destruction of physical living environments (forests, grasslands) or indirect disruption of food chains (toxic insecticides).
