What if?

I see cows on the land of a farmer
They are chewing grass like everything is allright
I see grass, green grass with morning dew
The grass is holding the dew like they are super strong
I see trees, brown trees with no leaves
The trees are standing there like having no leaves is no problem at all
But what if the cows can’t chew grass anymore?
What if the grass can’t hold the dew anymore?
What if the trees won’t have no problem with having no leaves anymore?
Will they never be afraid to the change that might come?
Will they never be afraid if everything is gone some day?
Or can’t they be afraid?
