This is a story about one horse, who lived many years ago in this world. He lived, worked, enjoyed as every horse, but he didn’t like it. He wanted to be a bird. He grumbled all day for natural:
“That’s very unfair, the bird only flies and poor old horse has to drag himself on roads.”
He abused like this whole month and then the horse was changed to the bird.
“Hooray! I’m a bird, I can fly!” shouted our horse. At that time, there was very high layer of atmosphere around the world, perhaps twenty times bigger than today. And when the horse changed his form, the atmosphere of Earth dwindled a little.
Our horse was satisfied about one month. After that he started to complain of the bird’s life. He thought it is boring. The bird just flies in great height, where is very cold, otherwise the bird does nothing. But a hippo has gorgeous life! He lies in the water, which cools agreeably and he doesn’t take pains of anything. And our horse - bird became hippo.
“Oh, that’s super! I can swim!” enjoyed that, but no for a long time. He was grown tired loaf in the water. He wished for be a peacock. The peacock can be proud of his nice tail, he is rich, handsome and everybody envies everything, what the peacock posses. Some days passed and suddenly, the horse - bird - hippo was the peacock.
“I am handsome, rich, admirable, noble and I don’t have to be ashamed of my pride. That’s good!” cheered the horse, sorry, the peacock. However, he thought badly. He was mistaken. “Bah! The peacock just opens and closes his tail, so isn’t it boring? Doesn’t such beetle have better life? I want to be a beetle, I desire that and I must be a beetle!”
So the dissatisfied horse - bird - hippo - peacock changed to the beetle. Our atmosphere decreased fairly again.
But very early the animal can feel himself dissatisfied. He was almost crushed by lots of people in one day and he started to complain immediately. “Is it a life? I only have to pay attention; or else somebody will crush me. I want to be a grass and it’s my last word. Howgh!” So the beetle became grass.
Straight after this moment, a cow grazed on the meadow, where was the horse - bird - hippo - peacock - beetle - grass, and it happened that the cow ate our dissatisfied grass...
And for the sake of one dissatisfied horse our Earth has her atmosphere thinner than before.
