This poetry thing is not leaving my responsibility,
I have so many things I would rather do
But I’m reminded I would be planting a tree by entering one
So I do
I’ll write something about 
“A sunset hugging the edges of buildings,
Unwilling to let go.
While the snow of the far mountains refuse to leave, 
No matter how hard the wind tries to push it away
Just below, the sea stuck in an endless cycle of self-hatred,
Pulling in pollution to one side as another pushes it away
It’s not going anywhere, 
Humanity put it there, only humans can solve it.
As unwilling as they may be it is their responsibility.
They can try to push it away, ignore it, let it pile up 
Until they drown in their own fiery water of regrets.”

You might read it as a metaphor, for death maybe.
It’s not, it’s fancy words describing the current weather.
Your guilt knowing you have helped this harm tells you it’s a metaphor.
If it helps you sleep, picture it as one, nothing more than a metaphor
Describing a world of the future, not one of your concerns.
