Quotes: Death World

The Mind Worms are the natural defenses of the living Planet—the white blood cells, if you will. In a world in which unassimilated thought represents danger, the Mind Worm seeks out concentrations of sentient mental energy and destroys them, ruthlessly and efficiently.
Commissioner Pravin Lal - "Mind Worm, Mind Worm" , Sid Meierís Alpha Centauri

You are not in Kansas any more... you are on Pandora, ladies and gentlemen. Respect that fact every second of every day. If there is a Hell, you may want to go there for some R&R after a tour on Pandora. Out there, beyond that fence, every living thing that crawls, flies, or squats in the mud wants to kill you and eat your eyeballs for jujubes. We have an indigenous population of humanoids here called the Na'vi. They're fond of arrows dipped in a neurotoxin that will stop your heart in one minute. As head of security, it's my job to keep you alive. I will not succeed... not with all of you. If you wish to survive, you need to cultivate a strong mental attitude. You've got to follow the rules - Pandora rules.
Colonel Miles Quaritch on Pandora, Avatar

The krogan evolved in a hostile and vicious environment. Until the invention of gunpowder weapons, "eaten by predators" was still the number one cause of krogan fatalities. Afterwards, it was "death by gunshot".

TRAVEL ADVISORY: The ecology of Tuchanka is deadly. Nearly every native species engages in some predatory behavior; even the remaining vegetation is carnivorous. Travel beyond guarded areas is strongly discouraged.
Description of Tuchanka, Mass Effect 2

This planet is one giant death trap.
Liara T'Soni's succinct commentary on Tuchanka, Mass Effect 3

Ramden: Down there they have anti-tornado warnings.

Oscar: What's it gonna be like up there?
Truman: 200 degrees in the sunlight, minus 200 in the shade, canyons of razor-sharp rock, unpredictable gravitational conditions, unexpected eruptions, things like that.
Oscar: Okay, so scariest environment imaginable. Thanks. That's all you gotta say, scariest environment imaginable.

They got Hood-damned demon farmers! Sowing seeds, yanking teats, spinnin' wool - and chopping strangers to pieces! Gesler, old friend, I hate this place, you hear me? Hate it!

Char. If hell ever existed, this is it. Oceans of fire, tectonic storms, and an atmosphere that will burn a man alive.
General Warfield, Starcraft 2

This is a Class 1 quarantined planet. The threats we will be facing are real. Everything in this planet is evolved to kill humans. Every single decision we make will be life or death.
Cypher Raige, After Earth

On Felucia, the Seps dug their metal heels into the muck of that alien hellhole and dared the Republic to come in after them. So we did, only to be met with month after month of flesh-eating diseases, shrieking nocturnal predators and other sights that haunt me to this day.
Anonymous 501st clone trooper, Star Wars Battlefront II

God created Arrakis to train the faithful.

Life is war.
There is no safe place. (...) All the world is a vicious, hateful realm of violence and savagery and it wants to hurt you and destroy everyone you love for your tears and despair are as water to its roots.
To surrender to it, to accept any form of compliance or the slightest shred of a moment of weakness, is defeat. This defeat is death. Death a thousand times, ten billion times fold, and the worst of it will be your own certain knowledge that you lost.
