Researchers Find Roads Shatter the Earth's Surface Into 600,000 Fragments (phys.org) 143

An international team of conservation scientists have released a new global map of roadless areas that shows that the Earth's surface is shattered by roads into more than 600,000 fragments. While roads allow humans to travel to nearly every region in the world, they severely reduce the ability of ecosystems to function effectively. Phys.Org reports: Recent research carried out by an international team of conservation scientists and published in the journal Science used a dataset of 36 million kilometers of roads across the landscapes of the earth. They are dividing them into more than 600,000 pieces that are not directly affected by roads. Of these remaining roadless areas only 7 percent are larger than 100 km2. The largest tracts are to be found in the tundra and the boreal forests of North America and Eurasia, as well as some tropical areas of Africa, South America and Southeast Asia. Only 9 percent of these areas undisturbed by roads are protected. Roads introduce many problems to nature. For instance, they interrupt gene flow in animal populations, facilitate the spread of pests and diseases, and increase soil erosion and the contamination of rivers and wetlands. Then there is the free movement of people made possible by road development in previously remote areas, which has opened these areas up to severe problems such as illegal logging, poaching and deforestation. Most importantly, roads trigger the construction of further roads and the subsequent conversion of natural landscapes, a phenomenon the study labels "contagious development."

    600,000 may sound like a big number. But consider that the Earth's land surface is 197,000,000 mi^2 (sorry for the imperial units, figure it out). So, roads "shatter" the Earth into average sections of 328 mi^2. Big woopee-doo.

    ("Shatter?" Unless the claimant can find lots of roads which have created fault lines in the Earth's crust, that's a troll at best, and more likely a deliberate falsification to support an agenda.)

      It's because the root claim is preposterous. Ecosystems span roads no problem. They don't span cities too well though.

    • Actually, 600,000 sounds like a really small area when you think that my block would be a section defined by roads. Later on in the article (which is an article that discusses the actual article) it says "They are dividing them into more than 600,000 pieces that are not directly affected by roads." So the 600k sections represent areas that we haven't really screwed up yet. I noticed on their map that they don't include Antarctica so I don't know if that's in with their calculations. There's one section w

    • Dude, you've not been to wilderness or semi-wilderness areas? Roadkill (and its railway cousin, train-kill) are just the visible surface of the iceberg. Roads segment ecosystems: its true. Even snails that get trod on on pavements are an illustration.

    • Unless the claimant can find lots of roads which have created fault lines in the Earth's crust

      Who said anything about fault lines, who said anything about the crust? The roads have most definitely created lines on the earth's surface. English doesn't care for your pedantry.

      • The word "shatter" denotes activity much more violent than making a line. The headline's most reasonable interpretation involves earthquakes.
    • The original article is not innumerate. It describes the distribution of sizes of road-free segments and considers what sort of land these are. Even in the abstract (which you obviously haven't read) states that since 80% of the planet has no roads "only 7% of land patches created by roads being greater than 100 km2." Thus, in the areas where there are roads, the road-free patches tend to be very small.

        "80% of the planet has no roads"

        That's a completely idiotic statement. It implies that roads cover 20% of the planet's surface. Nonsense.
        • Yeah, it's not clear to me if they are saying that literally 20% of the land's surface is covered by roads or that 20% of the land is defined as areas that contains roads. The latter seems more likely.

      ummmmm yeah..... your number include the liquid portion. In addition you are falling victim to the fallacy of averages (in this case the mean).

      A better word than "shatter" would be "segment".

  • by Anonymous Coward

    To 'fix' critical ecosystems, could we 'bury' sections of roads (either by tunneling, or building 'hills' over the top of existing roads? (the latter being easier in places which cut through hills already)

    Should future roads be built underground/at the treetop level?

    Data for data's sake is fine, but recommendations need to come out of this.

  • ... the human species is responsible for devastation across all ecosystems on the planet. Over 7 billion of these creatures are multiplying like a cancer. They consume vast quantities of resources, they destroy ecosystems. There is plastic waste in the ocean, overfishing which is decimating the fish population, pollution of ecosystems, and radiocative waste from nuclear bombs and powerplant accidents. And new humans begat even more of these damaging beasts.

    I'm always hearing about cars hitting deers. In my neck of the woods it's cars hitting squirrels. Every couple years there is a big media splash about how we're spending millions so wildlife can take underground tunnels and not turn into roadkill on a 70 mph road. Keep in mind, this is where squirrels are the issue.

    So who is surprised wildlife habitat has been divided into x times 1000 little bitty chunks, each too small to support the wildlife?

    Too many people, not enough land.

    • I'm always hearing about cars hitting deers. In my neck of the woods it's cars hitting squirrels.

      Maybe in your neck of the woods. I-70 in Pennsylvania has those Jersey barriers running all up and down the road, with no gaps or dips or anything.

      One night at 4 AM I was driving down I-70 and right after a blind curve my headlights fell across a herd of deer in the middle of the freeway, all trying to figure out how to get past this stupid concrete barrier that's too high for deer to jump over. So of course I find myself slamming on the brakes and swerving the car through a wild stampede at about 50 mph.

    Loaded word presenting a non-neutral POV. Reword and try your submission again.

  • Flying cars.

    Remember, you heard it here first.

  • The humans and vehicles running across the surface are there?

  • Click-whores gets fucked in the ass, after they die.
    The rest of us go to heaven.

  • According to this, um, 1950s Popular Science magazine we will have flying cars any day now. Problem solved, no need for those pesky roads all over the place.

    They need to stop putting deer crossings in places with high traffic.

  • The roads they are talking about are not in metropolitan centers. If plants before "man" can transverse from Europe and Asia to the the Americas then I doubt a simple two lane "road" is going to stop nature.

  • The vast majority of the 'roads' in the study are the little two-laners that twine everywhere, but have no effect on ecosystems other than to limit the spread of wildfires. An ecosystem is disturbed when a major, fenced-off highway carries a lot of traffic, and as the article admits the primary impact is the human population the road brings, rather than the road itself.. Around here the perennial debate is, do we fence off the rural Interstate as the construction standard specifies or do we let elk and coyo

      > but have no effect on ecosystems other than to limit the spread of wildfires

      This claim is not well founded, I'm afraid. Even the most casual look at Google shows thousands of well written articles on the difficulty, and many well researched scientific papers on obvious and subtle effects. Slower moving animals like snakes and turtles are devastated by roads, and can lose genetic diversity because they can't safely cross roads to cross breed with even nearby habitats. And animals that need to migrate due to winter or due to local food depletion often have profound difficulty finding safe and effective ways past piles of fenced in highway.

  • If anyone should examine a topo map of North America and give a reasonable estimate as to which major land contours, lake systems and other land features were either caused (or prevented) by the specific actions of BEAVERS, the rodents would be singled out in an IPCC report as a major cause of 'climate change', exposed by CNN, trash-talked on The View, sold bogus 'log pullers' [youtube.com], and hunted down near extinction. We could begin by interesting Europeans in beaver pelt clothing...
