  "description": "Adjusted to Firefox 4.\nTigers are considered an Umbrella species, and as such, trigger a top down chain of species die outs and habitat failure with their extinction. Once an Apex predator dies off, former prey populations that were once controlled by predation become rampant in numbers without a food source to sustain them."
