Years before the Odinson mixed it up with Ego the Living Planet or the Autobots struggled against Unicron's Orsonwellesian might, the Big Red Cheese found himself going mano-a-planeto with a sentient planetary body which may be familiar to most of you...
"Captain Marvel Battles the World" (from Captain Marvel Adventures #148, September 1953; by Otto Binder & C.C. Beck) is narrated by Earth itself. (For some reason I imagine Earth sounding just like Sterling Holloway.) After a quick introduction guaranteed to outrage the creationist crowd...
...the third planet from the sun outlines its grievances with the rapacious parasites that infest its crust:

In retaliation against those who have ravaged and plundered and ripped it and bit it, stuck it with knives, et cetera, et cetera, the Earth plays some meteorological hardball...

Forget carbon emissions and CFCs, the real "inconvenient truth" is that the Earth hates the human race...which is why it is our solemn duty to beat the planet into submission for the sake of
Earth's global warming gambit is foiled by Captain Marvel, who evaporates an ice meteor in the upper atmosphere in order to restore Earth's cloud cover (while worsening the greenhouse effect, providing a catalyst for massive tropical storms, and causing massive coastal flooding. Eh, it happens).
Not the type of heavenly body to be put off by a minor setback, Earth attempts to shatter the cities and works of man by slamming a couple of glaciers together with tremedous force, sending destructive shockwaves across the face of the globe. This plan also fails due to Marvel's intervention, which takes the form of a giant felt suppository crammed up the Earth's south pole.

This indignity only serves to further fan the flames of Earth's anger, and in its rage unleash a cataclysm on a continental scale of improbability...

...which might have worked, except for the fact that wild implausibility is the coin of Marvel's realm and the basis for all transactions conducted therein. Unprecedented devastation unleashed by a rogue continent set adrift? Big deal. It's nothing that can't be fixed with some glue and a little elbow grease...

Realizing that half-measures will not do when faced with the World's Mightiest Mortal, Earth decides to pull out all the stops and simultaneously unleash the entire gamut of global catastrophe in order to put an end to its human infestation problem. Before the fireworks can commence, however, a renegade comet crashes the festivities and threatens to pulverize the poor Earth.
Fortunately for the hapless planet, Marvel isn't the type of guy to hold a grudge, and applies a little Atomic Age know-how (long on infatuation, short on realizing the consequences) to save the day...

The comet is destroyed (with only a 10,000% increase in global cancer rates following Earth's passage through the plutonium-laced debris cloud; Marvel is a strict utilitarian), and a chastened Earth is treated to a sanctimonious lecture by the Moon, who, it should be pointed out, lobbied hard for restricted community status after the Apollo 11 landing. "I do think humans are cute; I just think they should be cute somewhere else."

1919 - Earth Song (from a 1984 EP; collected on The Complete Collection, 2001) - Crunchy goth fare reminiscent of Killing Joke's punkier stuff. Comrade Highlander posted a rip of the entire EP a few months back, and while the hard copy of the collection is currently out of stock, the mp3 version can be downloaded from either Amazon or eMusic.
Blue Cheer - Ecological Blues (from Oh! Pleasant Hope, 1971) - Blue Cheer's heavy-duty blues-rock sound (and their cover of "Summertime Blues" on 1968's Vincebus Eruptum LP in particular) are frequently cited as one of the seminal influences on the heavy metal genre. While it's a valid observation, it does overstate things (as most proto-genre assertions tend to do) and overlooks the bizarro-psych side of the band as represented by this head-scratcher of a musical timepiece.
The Gun Club - Eskimo Blue Day (from Pastoral Hide and Seek, 1990) - ...and occupying the genre shadowlands between today's offerings from 1919 and Blue Cheer comes this swamp-punk-blues cover of one of Jefferson Airplane's better efforts (as opposed to the two tracks by the band that get heavily played on classic rock and oldies format radio).
