OF TAKING
TOO MUCH
These histories show why protection must begin before a population reaches its last few individuals.
Thylacine
Bounty hunting, persecution, and habitat pressure contributed to the disappearance of the Tasmanian tiger.
Whaling Crisis
Industrial whaling pushed several great whale populations to the edge, leading to international restrictions.
Illegal Trade
Poaching, wildlife trafficking, and accidental bycatch still threaten rhinos, pangolins, turtles, and cetaceans.
A lesson for every species: population decline can accelerate faster than recovery.
