Humans have negatively impacted several endangered species in Africa. Black rhinoceros have been poached for their horns for use in Chinese medicine and jewelry, reducing their population. Gorillas have been poached for their fur and lost habitat to development, endangering the species. The geometric tortoise, with only 2,000-3,000 remaining, has been poached for its decorative shell. Conservation efforts have established protected areas and regulations, but continued protection is needed to ensure these species' survival.
