Changing Planet Revealed In Atlas 150

Posted by Zonk from the icky-grossness dept.
ring writes "The United Nations Environmental Programme (Unep) has released a new atlas 'One Planet Many People: Atlas of our Changing Environment', to mark World Environment Day (WED). It compares and contrasts spectacular satellite images of the past few decades with contemporary ones." From the BBC article: "Among the transformations highlighted in the atlas are the huge growth of greenhouses in southern Spain, the rapid rise of shrimp farming in Asia and Latin America and the emergence of a giant, shadow puppet-shaped peninsula at the mouth of the Yellow River that has built up through transportation of sediment in the waters."

        Doubtful... Results like that are what enviromentalists are working for. If no one draws attention to environmental problems, there are not going to be any solutions.

        I'm sure there are many satellite images of remote areas that haven't changed in the last 30 years, but that doesn't mean that looking at the changes (good or bad) isn't important.

        Did you even look at your own link?

        For those who haven't, it shows tons of virgin forest spread over the US in 1620 and 1850, then a dramatic reduction by 1920, and recently some regrowth, but still only perhaps a quarter of what was here pre-massive deforestation in the late 19th and early 20th centuries.

        This is a great argument for the work of environmentalists.

      • "Forest" is land covered in trees, but the reforestation in most of the US is nothing like the original forest. It is greatly reduced in species diversity at every level, from trees, birds, mammals, and right on down to the microbiota.

    In North America at least, the trend has been going largely in the opposite direction. We are seeing REforestation rather than DEforestation. This is in despite of an increasing population.

    It can be a little tough to find good data given all the bullshit flying around but here's a map that shows the amount of forest land in the US from 1620 onwards:

    http://www.eia.doe.gov/oiaf/1605/gg96rpt/chap7.htm l [doe.gov]

    The interesting things is that we are see a dramatic resurgence of forest land here in the US. A big part of the reason, apparently, is more efficient farming practices which have allowed us to restore a lot of farmland back to forests. Here's a map showing the trends from 1982 to 1997:

    A move to more densley packed cities is also a contributing factor to reforestation.

    Article such as the one Zonk cited are a favorite of the hard left environmental movement. These 'studies' cherry pick data to paint an alarmist picture. The media usually swallow these article whole with little crtical thought. In the end, these distorted pictures don't do anything to help real environmental progress.

      One critique of these maps is that they are not comparing like with like. The forest clearing shown in http://www.ers.usda.gov/Briefing/LandUse/Gallery/m ap1.htm [usda.gov] is happening mainly in the old growth forest in the rockies. New planting in the east is often plantations of pine trees and other commercial forestry. While it is good that total forest cover in the US is increasing an old growth forest has a much greater biodiversity than a comercial plantation. Old growth forests will have many different species of trees at a variety of different ages, they will support many sorts of wild-life, bears, wolves, rare owls, and all manner of other plant and insect life. A conifourous plantation can be close to monoculture with rows and rows of a single species, often the dense planting and the blanket of needles supresses any low growth. Thankfully there is a trend towards better forest management today, but an old growth forrest is ireplacable.
      • What's so great about old growth forests? A friend of mine from Maine is a history buff. He told me about the American invasion of Canada in 1775. Benedict Arnold (yes, the infamous Benedict Arnold) led 1100 soldiers up through Maine to Quebec. It was a disaster. Many of his soldiers died from starvation. That seemed odd to me, why didn't they just shoot some deer or other game?

          Old Growth Forests = Large Trees (like sequoias [red woods]). Those types of trees keep undergrowth (bushes, grass, etc) from forming. No undergrowth means no deer or anything else of similar size. Old growth forests are nice, but have almost no plant life. The suck for biodiversity. I'd prefer softwood forests, personally.

          Scientifically, irreplaceable means that the habitat, once lost cannot be replaced. For which there is a lot of evidence. At its simplest it would take 180 years for the canopy to reform, and this would only happen if the land was managed with habitat recreation in mind. What is more likely is that the land will be managed as commercial forestry with perhaps a 100 year cycle, never reaching the same level of biodiver

    The problems we face in terms of climate change and shifts in the parameters of the biosphere are matters of conjecture. Apologists from any one camp can float an argument to support their agenda. It's reminescent of Winston Churchill's quip: "These, gentlemen, are the opinions upon which I base my facts." In a political arena opinions are as likely to take the day as are facts.

    Maybe the point to be highlighted is one of judgement. If you're crossing a rope bridge, over an abyss, and, you think it's showing signs of giving way, do you sprint for the other side or do you go gingerly, testing as you go, looking for more proof of what's happening? In the first world, the infrastructure that maintains our lifestyle is not ruggedly robust, or, highly redundant. Redundancy as a concept is, historically, only yesterday's news. The internet is an example of an infrastructure built with redundancy in mind. So, if the biosphere is showing signs of change, do we hope for benign change and/or for science to sprint to the rescue? Sir Francis Bacon [utm.edu], one of the fathers of deductive reasoning, suggested we had to wrest the secrets of life from nature, like a mythological hero wresting a prize from some monster. I think many, maybe all of us, are subject to living, in part, in the heroic age, and, I think that is the greatest danger. The ancient Greeks fostered the idea of hubris as one of mankind's greatest weaknesses. The philosophy of the heroic age doesn't hold in an indeterminate universe and science shouldn't be seen as the ultimate big stick that will beat back the threats of nature.

    Life, as we know it, is characterzed as an non-equilibrium, open-system. The sun rains down ~10^24 calories per year on the biosphere. Carbon based life forms, in the perfect mileu of water, harness this energy in various ways.But it's a system of systems and subject, as much as we know, to Systems Theory [wikipedia.org]. If we know change is in the works do we risk positive feedback [wikipedia.org] and trust in science to carry us past any threat?

    There is a strong consensus that climate change is happening. [bbc.co.uk] Will climate change force a parameter shift that will invite a runaway state? The concept of key species tells us that specific species are necessary to maintaining the ecology of an eco niche. Could climate change destroy key species and cause collapse of ecosystems. This brings on the old bogey man of the domino effect.

    Change is inevitable, so it's really a matter of placing your bet on science as the ultimate super hero, or, do we begin to exercise caution now to mitigate against change. After all there's no place like home.
