Across Tanzania, big cats are suffering from scorching heat, unforgiving dust storms and water shortages. Once teeming with wildlife and flowing with water, the Ruaha River is empty except for a smattering of scorpions and lethargic animals too weak to follow their herd.
In this region, there are few remaining pools of refreshing water, and the lines between predator and prey blur as each searches to quench their thirst at the watering hole.
In this life-or-death battle, animals must secure a spot at a claimed water pool or resort to lapping up muddy puddles pooling in elephant prints. Competition — as well as survival — is a constant battle.
Exhausted lions, hyenas, vultures, leopards and jackals stalk the watering holes as giraffes, impalas, zebras and jackals are forced to risk their lives for the sake of hydration. And they must hurry to drink as quickly as they can — hundreds of buffalo are on their way. These massive animals require at least eight gallons of water a day for survival, and the future of this particular water spot is bleak at best.
