* Peter F. Hamilton's ''NightsDawn'' trilogy contains a planet called Garissa. Or rather, did. It was sterilised with antimatter-fueled "planet busters". In effect, they caused planet-wide radioactive hurricanes that would rage for centuries.

* Scientists predict that the Sun's luminosity gradually increases; in about a billion years, Earth will become too hot to sustain life[[note]]''Complex'' life at least, and maybe some more time (1.2 billion years). Simple lifeforms -bacteria and the like- may last until 2.8 billion years in the future[[/note]].

* In ''ComicBook/TheSupergirlSaga'', the Phantom Zone criminals accidentally let loose on the Pocket Universe Earth by its Lex Luthor decide that humanity is too troublesome to rule over when they build a LaResistance powerful enough to resist the Kryptonians, and so the criminals destroy the Earth by destabilizing the Earth's core, causing hot gases to erupt and burn away the atmosphere, stripping the planet to a lifeless husk except for the Smallville citadel of Lex Luthor. Eventually, though, that gets destroyed along with the remaining humans before Superman from the mainstream DC Universe puts an end to their threat for good by using the universe's native Gold and Green Kryptonite on them.

* ''WesternAnimation/StevenUniverse'' showcased Gem Colonies as being highly detrimental to the host planet itself. While the Earth has local Class 6 spots, should the colony become successfully established, the result would be an Earth fit for Gems to live on, but the planet no longer hosts organic life... Even worse, when considering the murals of the Diamonds, this event must have happened many times to other life-bearing planets, potentially including Homeworld itself.
