NASA's idea
We currently say By volume, the ocean provides about 99 percent of the living space on the planet, sourced to NASA. The writer is counting the sea three-dimensionally but the land two-dimensionally. (Or nearly so, since otherwise it would be 100 percent.) Alternatively, they may just be dividing the figure of 3% (the amount of water that is freshwater) by three because the land covers about one third of the Earth's surface. This makes even less sense, and reminds me of the bellboy problem.

If we apply the logic of the NASA writeup to its end, why not count the sky? So much of the ocean is completely devoid of life that it is comparable to the vast areas of open sky. Since we have found birds flying at 10km above the surface, I declare the sky the largest habitat on Earth by far.

I've come to dislike back-and-forth arguments in articles, since it just belays the important points of the writing, so I don't really want to add the sky argument in right now. But perhaps we don't need to bring up the unfair 3D vs 2D comparison in the first place; it should be on point enough to just mention that the ocean is larger by surface area than the land and freshwater habitats combined. Thoughts? — Soap — 17:58, 13 October 2019 (UTC)
 * I found something that actually makes the claim even stronger, so the problems with NASA's claim are moot. At least to me, they are ... the article doesn't say anymore that the ocean contains 99% of the Earth's "living space", but that they contain more than 99% of the world's liquid water. — Soap — 01:30, 14 October 2019 (UTC)
