Pollution

Genetic changes
Abnormal born
Air pollution
Land is destroyed
Prenatal exposure to air pollution
Genetic changes that predispose unborn

Evolution
Air pollution
Burns as hell
Soon will see the end
Revive dead tissues
We pretend to be god
Extinction
Knocks on heavens door

System damage
City smog
Floating among us
Threatening to destroy
Nature's revenges
Among us
Eye for an eye
For what we killed
What we killed

Genetic changes
Abnormal born
Air pollution
Land is destroyed
Prenatal exposure to air pollution
Genetic changes that predispose unborn

Drugged by our own mistakes
We wish to forget
Zombies we became no control of ourselves
Bio-weapons, we are the weapons hosts
Ticking to explode
Drugged by our own mistakes
We wish to forget
Zombies we became
