The world’s natural places are disappearing at a galloping clip, says a new study, released Friday in the journal Science Advances. It suggests that more than 7 percent of Earth’s natural, intact forest landscapes have been lost since 2000 — and these ecosystems may be in danger of disappearing entirely from at least 19 countries in the next 60 years.
These landscapes represent some of “the last portions of the Earth that are not significantly affected by human influence,” said Lars Laestadius, a forest expert, consultant on natural resources policy and co-author of the new study. “As we lose these, we lose something that is bigger than ourselves.”
The study defines “intact forest landscapes” as areas greater than 500 square kilometers, or 193 square miles, containing a mosaic of forests and other associated ecosystems, such as plains or wetlands. The key is that these areas must be undisturbed by human activities — they can’t be fragmented by roads or deforestation or other industrial operations. Once that happens, the ecosystems cease to be considered “intact.” And as the new study indicates, this is happening more and more frequently around the world.
