The majority of this fanfic is based on the 1970 film No Blade of Grass also known as The Death of Grass directed by Cornel Wilde, and not upon the original novel by John Christopher or any other adaptation.
Dr. Pamela Isley saw how the world worked like she had already seen its entire lifespan. By 2022, levels of pollution long gone since the first Earth Day had risen once again. Thanks to a recent battle with the Justice and Injustice Leagues in Washington that nearly destroyed the headquarters of the Environmental Protection Agency, the agency itself was teetering on the point of bankruptcy, if not for the government stepping in to supply everything it could for the destruction of both the agency and other buildings that fell victim to the attack.
But that wasn't the worst of her troubles.
Everywhere she looked, or sensed, she could imagine the repulsive sight of billowing smokestacks emitting toxic clouds, strip-mining, pesticides, oil spills, red tides soaked with dead water birds, starving citizens from third-world countries, cars producing deadly gasses from their engines and the industrial wastewater poisoning almost every life under the sea of Gotham Bay.
Even though she was safe in her botanical garden, killing other tormentors to the Green by during them into dogwood, the world outside her walls was still in danger.
"Batman, his little partner and his also younger friends go after the people," she thought. "They need to narrow their horizons onto the people who bringing nature to its knees."
There were other members who were connected to the Green, like Swamp Thing, Flora Black and Suzy Linden, but even Demeter, the Greek goddess of nature, would have disapproved of their compassion towards humanity and if humanity was more important than nature…she was going to give them a taste of their own medicine.
A virus was all she needed to make humanity crawl on its knees for their crimes against Mother Nature, a virus was efficient to kill off every member of the grass family, a virus was the most important ingredient needed to see humanity resort to cannibalism.
Poison Ivy, as she called herself, was willing to kill the very thing she loved the most for the most evil plan she had concocted yet: creating a famine that would kill every homo sapien but herself and then starting the world all over again with herself as Earth's sole passenger. Meanwhile, she would be safe and sound inside her little greenhouse…waiting for her plan to come to fruition.
First, the virus would strike Gotham City, then Metropolis, then the crops of Smallville and finally…the world. Meanwhile, her lair would be guarded by hungry Venus fly traps that would threaten those who would try to invade her garden for food, Kryptonite-laced thorns that could penetrate even the strongest of Kryptonians like Superman and his family, vines that could never be severed by the sharpest of Themysciran swords and creepers that would deflect the powers of Captain Marvel and the Martian Manhunter.
All Ivy had to do was wait, as the food supply was cut off and once the last human left his home, the Earth would be hers for the greening.
