At A World's End: Mason East

It's been 25 years since the war had started... It's been 20 years since it ended. Along with civilization itself.
The human race dominated the Earth. We were the top species. But we took for granted all that our Earth gave to us, and we were abusing the privilege to live on the most beautiful planet in the Milky Way. We were killing her.
In 2019 we realized this, but by then it was already to late. A huge uproar occurred. People began to panic, and with panic comes conflict, and when the human race is involved... Conflict... Breeds war.
In 2022, a Great World War erupted into life. Nuclear weapons were used to wipe out any enemies before they could cause any serious trouble. But the Earth had other plans. Our Mother Earth... Was finished with us.
She took our weapons and turned it against us. The atmosphere of our planet, consumed the nuclear chemicals. Mother Earth drank it like a glass of fine wine. Our home began to change. In ways children shouldn't have to see in their lives.
The sun scorched everything humans had made for themselves, killing us as well. Then the rain came. Acid, blood red acid, cried from the heavens. Burned our homes and families. It ate away our skin, while the air poisoned our lungs.
What once was beautiful flora and fauna, adapted and evolved specifically to kill off humans. They grew vicious, big, and have no complexion for being polite.
But we survived. We always have. Now we live in the wastelands of what we once built. Killing each other to survive, or for the hell of it.
I personally hope the human race dies out. We did this to ourselves and to our planet.
But I... I will survive.
I'm Hal East, and this is my story.
