Free Opal: The Loneliest Orangutan Opal has spent decades in solitary confinement at the Natal Zoo in South Africa. She lives in a barren, concrete enclosure with no trees to climb or companions of her own kind. Why she must be rescued: Mental Health: Highly intelligent and social, Opal shows signs of deep depression from years of isolation. Better Life: Sanctuaries like Monkey World offer a natural environment where she can finally live with other orangutans. Dignity: After 45 years of captivity, Opal deserves to spend her final years in a place that meets her physical and emotional needs.
