The Great Migration

In the distance there is thunder without rain.
Dry dusty hooves pound the Serengeti plain.
Ungulate masses clog thickets and bayobab trees.
Miles and miles of wildebeest, far as the eye can see.
Some find greener pastures, others a merciless fate
as lions pick off stragglers and crocodiles lie in wait.
Each year the Summers are hotter, the herds smaller and smaller.
Time marches on for progress and pursuit of the almighty dollar.
