An utterly simplistic read. No wonder you like it. He ignored vast amounts of information just on the Greenland Vikings in one case, just so he could make his case.
Cherry picking in the extreme. I suggest you look at some of the more recent peer reviewed archeological information that has come out over the last ten years.
That's the problem with all of you. You read something that just touches the surface and somehow think you're experts all the while ignoring the vast ocean of information that's out there.
Although I can't vouch for his research on Vikings, I have several books and documentaries on the mayans. And his findings coinceed with the current arqueological findings of Mayan decadence.
Also, in Rapa Nui the harsh truth is self-evident if you take a look at the island: it has no trees at all. The explotation of their forests was not sustainable and brought them to a civilizational collapse.
What I find so unsettling about your comments is the fact that you haven't provided a single reference to support your statements.
Are "trees" our problem here? The sustainable folks TODAY want to grow stuff just to burn it for power.. In a failed attempt at logic and math -- they account for that as "zero carbon" and sustainable.. I think maybe the folks on Rapa Nui were just executing their 200 yr sustainability plan..
You might be surprised, but I agree with you on biofuells mostly.
Switchgrass is the only plant that has a good energy ratio ( 5 to 1 by most accounts), of course, the downside is it uses arable land which can be used to produce food so it must be used sparingly.
