A new study shows that our planet has 10% less wilderness than in the 1990s.

Ten percent of Earth's wilderness has disappeared since the 1990s, according to a new study published in the journal Current Biology.
Over the last 20 years, we've lost a total area amounting to twice the size of Alaska, researchers report. But, experts say, there's still time to save the remaining wilderness areas – and they hope the recent findings will spur change.
At the moment, only about 23 percent of the world's land area is made up of wilderness, the study found. Most of this wilderness can be found in North Asia, North Africa, Australia, and North America (primarily the northern parts of Canada). South America has experienced the greatest loss, with a 30 percent decrease since the '90s, and Africa follows with 14 percent.
"The wilderness decline around the world is most in the tropical biomes, the tropical rain forests have lost a lot of wilderness," study co-author Oscar Venter, of the University of Northern British Columbia, told CBS News. "A lot of the Amazon has been lost, the mangrove ecosystems, which are really important wilderness areas have been hit. They are a nursery ground for a lot of the world’s wildlife – young fish are reared in these mangrove ecosystems, they are a base for a lot of the fisheries. Now, there is almost no wilderness left in the mangroves."
Other things from the '90s we have less of: golf visors and light up sneakers, so it isn't all bad.
The Alabama Center for Rural Enterprise worked with Houston’s National School of Tropical Medicine to sample “soil and water…blood and faecal samples” from Alabama’s Lowndes County, a poor rural area.
When inventor and MacArthur “genius grant” recipient Saul Griffith started reading papers about global warning that were written in 1974 (the same year he was born) he discovered that “all the problems we face today are familiar from 43 years ago. All the proposed solutions are similar. Merely the motivation was a little different.” In […]
Advances in Atmospheric Sciences reports that flying is going to get more and more turbulent, even at cruising altitudes, because of climate change:
Bamboo has lots of uses beyond just being panda food. Things like bikes, roads, scaffolding, and musical instruments are made from the fast-growing grass. But unless you are participating in a tropical-themed LARP, you probably wouldn’t want a shirt made from bamboo stalks. So why do bamboo bed sheets make any sense? Because yarn extracted from […]
If you want to work in tech, but don’t have any desire to code web apps to help businesses sell things to other business, you might want to consider a career in cybersecurity. Judging from the apparent complete infiltration of Russian hackers in American cyberspace, it seems fair to speculate that there’s a major shortage of […]
All moms are different. But all moms like getting flowers on Mother’s Day, and that’s a fact (not, however a fact we can document in any fashion.) Instead of getting chewed out for forgetting to call her on the second Sunday of May, you can take care of it ahead of time with Teleflora’s flower […]
