The reasons

Why does the sun always rise every day?

Because it wants to illuminate the earth.

Why does a brook always flow forward the seas?

Because it wants to embrace its mother.

Why does a plant vigorously grow?

Because it wants to green the land.

Why are the Alps so high?

Because they want to be moistened by snows.

Why do we live?

Because brilliant sunshine needs us to experience;

Because the beautiful brook needs us to dabble;

Because green land needs us to manage;

Because the Alps need us to appreciate.
