Disclaimer: Written when I was 15. I am deeply embarrassed by this one, but here for completeness.
Heat Death
The second law of thermodynamics:
Ordered systems tend toward disorder.
The universe prefers chaos.
Sometimes it feels like the world is falling apart,
Like we're slowly drifting towards the edge of an abyss,
And paddling, and flailing, and fighting against the tides-
Just futile deferral of the inevitable.
It will drag you down
Eventually.
So why bother fighting?
In the face of so much suffering, so much pain,
An unbeatable, unrelenting enemy,
Isn't it easier to just succumb to apathy?
Let its currents pull you under,
Rob you of your passion,
Of your empathy,
Gnaw at your insides until you can't feel
Anything anymore,
Leave you a hollow, empty husk
Of what once was.
Or do you resist?
Do you fight the futile battle,
Until the final breath of time?
Strive to create beauty, meaning, order
Knowing it won't last.
Because maybe there is still value to be found
Within the impermanent.
Maybe this cosmic anomaly we call Earth
Where atoms are aware of themselves,
Where beauty starts and ends
Is worth fighting for every last second.
