How much of Earth’s land is habitable?
The total land surface area of Earth is about 57,308,738 square miles, of which about 33% is desert and about 24% is mountainous.
Subtracting this uninhabitable 57% (32,665,981 mi2) from the total land area leaves 24,642,757 square miles or 15.77 billion acres of habitable land..
What percent of Earth’s land is unaffected by humans?
5%Why it matters: The new study finds that just 5% of the Earth’s land surface is currently unaffected by humans, far lower than a previous estimate of 19%. 95% of the Earth’s land surface has some indication of human modification, while 84% has multiple human impacts, the study found.
