ART IS NEBULOUS

You say that art is nebulous,
that it's ill-defined,
that we can't even explain
why we yearn for it   –
not like how we want food
for sustenance
or clothing for warmth.
That we just want art because
we "like it",
And we can't even define it clearly
or grasp the concept with our fingers.
You're right,
but art is like the wind above the ground,
nebulous, swirling, fleeting.
With only ground,
Earth would be barren.
But with wind,
the Earth is vast and wondrous.

I think the poem is sufficient though the form is imperfect.
Added "above the ground" after the first write to ensure the imagery.
The diction and meter can probably use a little work.
