The Last Green Planet

No one expected Earth to outlive her colonized daughters.

By the dawn of the 27th century, humanity had stretched itself across the stars like vines on a dying trellis. Mars was terraformed, Venus domed in breathable sanctuaries, and the moons of Jupiter turned into mining fortresses that never slept. The Earth, scarred and gasping, had long been abandoned—at least, that’s what the official records claimed.

But Earth did not die.

Somewhere beneath the ash layers and acidic seas, seeds waited. The planet healed in silence while the galaxy warred, mined, and forgot. The atmosphere thickened again. Oceans, although smaller, cleared. The forests returned—not the ones we remembered, but ancient, bio-luminescent cousins shaped by radiation and time. Earth had become green again.

And no one knew.

No one except the rangers.

Mira Alen stood at the edge of a living cliff in the New Amazon, a region once flattened by logging centuries ago, now risen like a jungle titan from myth. Vines pulsed like veins, leaves whispered in a language only the wind understood, and birds—real ones, not drone mimics—pierced the air with colors and songs long extinct elsewhere.

Her boots sank slightly into moss that glowed faintly under her steps. She pulled down her visor, the HUD scanning the perimeter for signs of unauthorized entry.

There was one.

“Got you,” she whispered.

A signal had broken through the planetary shield two hours ago—an illegal descent pod. Whoever had landed here wasn’t part of the ranger order. And that meant only one thing: a smuggler, a corp scout, or worse, a gene-raider.

She moved silently through the underbrush, her rifle slung on her back not for show but necessity. Earth was wild again. Not savage, but untamed. And she was its guardian.

She found the pod nestled in a shallow crater, its hull still steaming from atmospheric reentry. Footprints led away, deeper into the heart of the forest.

“Central, I’ve located the intruder’s landing site,” she said into her comm. Static.

Of course. The canopy here was too thick. She switched to short-range tracker mode and followed the trail.

Hours passed. Light filtered in shafts through towering tree-pillars. Once, a spindly shadow flickered past her path—possibly a carbon-augmented fox species they’d been studying. Beautiful. Terrifying. Necessary.

Then she saw him.

A man knelt near a cluster of blooming solis-flowers—delicate, golden blooms that could purify air better than any artificial scrubber. He wasn’t harvesting them, not yet. Just staring.

She aimed her rifle.

“Step away from the plants. Slowly.”

He raised his hands and turned. To her surprise, he wasn’t armored or corporate. He wore patched clothes, old tech at best. A scavenger?

“No need to shoot,” he said. “I’m not here to steal anything.”

“Then explain why you’re trespassing on a sealed planet.”

He paused. “I’m looking for a home.”

His name was Kael, and he claimed to be from Proxima B, one of the early colonies that had fallen to solar radiation after their shields failed. According to him, he was part of a dying remnant—genetically weakened, starving, out of time.

“They sent me to find somewhere... anywhere life could begin again,” he said, sitting beside a root structure that pulsed faintly with chlorophyll. “I didn’t think Earth would still be alive.”

She didn’t answer right away.

The Rangers were sworn to protect Earth’s secrecy. They kept her hidden because humanity, as it was, couldn’t be trusted with her again. Not yet. Maybe never.

“You can’t stay,” Mira finally said.

Kael looked up at her. His eyes weren’t desperate. Just tired. “Then tell me what I should report back. That the last green planet is off-limits? That we’re to die while Earth breathes alone?”

Mira felt something crack within her resolve.

That night, they camped beneath a bioluminescent canopy, and she listened. Really listened. Not just to him, but to the Earth. The buzz of insects, the thrum of photosynthesis in the air, the balanced hum of an ecosystem in recovery.

Could Earth truly stay hidden forever?

Or was this the moment she had been trained for—not to protect Earth from people, but to decide when it was safe to let them back in?

By morning, she had made her choice.

“You’ll come with me to Haven Station,” she said. “You’ll tell your people that Earth isn’t just alive. She’s sacred now. And if anyone returns, it will be by invitation only. With respect, regulation, and guardianship.”

Kael nodded, emotion flashing across his face. Not victory—gratitude.

And Mira looked out over the emerald horizon and felt the shift of an era begin.

The last green planet was no longer just a secret.

It was humanity’s final chance to get it right.
