Humans have a greater influence on the world’s landscape than previously thought, according to a comprehensive new high-resolution analysis of human modification of the planet. The map, published in the journal Global Change Biology, is meant to guide conservation strategy in the coming years.
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.
“As a conservation community we can’t just say once we’ve protected these last remaining wild places then we’re done because the vast majority of the world is not those places.”
