Lion
Individual lions live approximately 10-14 years in the wild, considerably longer in captivity where meals arrive on schedule and nobody attempts to steal them. The species itself has persisted for roughly 1.2 million years, surviving ice ages, continental shifts, and the inexplicable human desire to hang them on walls. However, lion populations have declined by 43% in the past two decades, according to the Nairobi Wildlife Census Bureau.
Freedom
Freedom, as a concept, has existed for as long as humans have recognised its absence. Archaeological evidence from the Stockholm Institute of Prehistoric Complaint suggests early humans were lamenting restrictions on their freedom at least 40,000 years ago. Unlike lions, freedom cannot go extinct. It merely waxes and wanes, resurging whenever someone feels insufficiently liberated by their current circumstances, which is to say constantly.
VERDICT
Lions face genuine existential threats. Freedom, being purely conceptual, will persist as long as humans exist to feel aggrieved by something, which statistical modelling suggests is forever.
