Fragmented Rainforests' Species and Carbon Much Diminished
Forest fragmentation is rapidly eroding biodiversity and worsening global warming [more] in the Amazon rainforest according to research to be published this week in the journal Proceedings of the National Academy of Sciences. Forest fragmentation [search] is the process whereby a large, contiguous rainforest landscape is cut into pieces by industrial logging (including what is sometimes called "selective" but opens large forest gaps creating fragmentation), large-scale cattle ranching, slash-and-burn farming, rapid soya expansion, and wildfires. "Fragmentation causes profound changes to forest dynamics and ecology, resulting in the disappearance of rare species and forest specialists." Fragmentation also has global climate impact since fragments experience a considerable die-off of trees attributed to drying winds and storms.
Perhaps the mainstream environmental ancient forest logging apologists that promote certified industrial logging as a "conservation" strategy in the world's last few large and relatively intact ancient primary and old-growth forests can explain how their support for such logging matches up to the overwhelming science that industrial logging of any type severely diminishes ancient rainforests. I pick the scientific observations of top scientists like William Laurance of the Smithsonian Tropical Research Institute in Panama over the hippie-dippies in Greenpeace and Rainforest Action Network, and the career bureaucrats with conflicts of interest in WWF, FSC and WCS. The science is clear – humanity must end ancient forest logging NOW if there is to be any chance of global ecological survival. If you are not working to do so you are a bad guy, on the wrong side of forest conservation history.
