What percentage of the Earth is impacted by humans?
14.6\% of the world’s land area has been modified by humans, according to research. This is equivalent to 18.5 million km², an area greater than Russia. Human impact on the Earth’s surface can take a number of different forms, including cities and towns, to natural systems modification.
What percentage of the Earth is built on?
Less than 30\% of the 510 million square kilometers of area on the Earth’s surface is covered by land. There are over 510 million square kilometers of area on the surface of Earth, but less than 30\% of this is covered by land. The rest is water, in the form of vast oceans.
What impact have humans had earth?

How much of Earth is inhabited by humans?
So on the one hand, you could say from these results that 10\% of Earth is inhabited by humans. Or you could take a more glass half-empty view and say that 90\% of Earth is covered by humans – either populated or connected with an ever-expanding network of roads, train tracks, highways, farms and industrial land.
How much of the Earth has been modified by humans?
As it turns out, nearly 95\% of the Earth’s surface shows some form of human modification, with 85\% bearing evidence of multiple forms of human impact. This map by data scientist Hannah Ker outlines the extent of humanity’s modification on terrestrial land ecosystems.
How much of earth’s land is affected by humans?
Only 5\% of the world’s lands are unaffected by humans, which amounts to nearly 7 million km² of the Earth’s land, and 44\% (59 million km²) is categorized as low modification.
How much of the Earth is covered by artificial surfaces?
Artificial surfaces include any areas that have an artificial cover as a result of human activities such as construction (cities, towns, transportation), extraction (open mines and quarries) or waste disposal. This figure gives us an estimate of roughly 900,000 km 2 of human-covered land worldwide.
