Zebra's distinct black and white stripes provided it with camouflage and survival for thousands of years. When zebra stands in high grass, its vertical stripes make the animal practically invisible for Zebra's main predator, lion, which is color blind. Zebras standing together in a herd also make it hard for predators to differentiate between individual animals when picking the one to attack.
Zebra's stripes have inspired many effective and creative designs - for instance the famous "zebra crossing" is even named after the zebra's black and white stripes.
Photoshop how life would be different if zebras ruled the world, by giving black and white striped paint jobs to any animals, objects, people, buildings, statues, etc.
