Humans Have Altered 97 Percent of Earth's Land Through Habitat and Species Loss. A study published on April 15 in the journal Frontiers in Forests and Global Change presents evidence that only about three percent of Earth's land ecosystems remain untouched by human activity.
What percentage of the Earth is occupied by man?
Human beings take up a lot of real estate -- around 50-70 percent of the Earth's land surface.What percentage of the Earth is modified by humans?
We estimate that humans have modified >50% of Earth's land surface. The current rate of land transformation, particularly of agricultural land, is unsustainable. We need a lively public discussion of the problems resulting from population pressures and the resulting land degradation.How much of the world is still undiscovered?
Most of our world is still shrouded in mysteryUnsurprisingly, we aren't. In fact, 65% of our planet remains unexplored, most of which lies beneath the oceans. Literally anything could be down there, and we wouldn't know.
