[Ugo Bardi] Extracted [young adult contemporary Book] ePUB – Book, eBook or free

READ Extracted

O Bardi delivers a sweeping history of the mining industry starting with its humble beginning when our early ancestors started digging underground to find the stones they needed for their tools He traces the links between mineral riches and empires wars and civilizations and shows how mining in its various forms came to be one of the largest global industries He also illustrates how the gigantic mining machine is now starting to show signs of difficulties The easy mineral resources the least expensive to extract and process have been mostly exploited and depleted There are plenty of minerals left to extract but at higher costs and with increasing difficul. We recently read Bill McKibben s OIL AND HONEY and the point that he made very clearly was that it really is beside the point trying to calculate how big the earth s fossil fuel reserves are because if we dig up and suck up and burn even a sizable fraction of the known reserves the conseuences for the planet will be disastrous And in COUNTDOWN Allan Weisman tells a story that leaves no doubt in this reader s mind that there is no level of resource consumption that is sustainable with a population of seven billion mainlining the myth of perpetual growthGiven that perspective the theorizing about if and when we might run out of any particular resource seemed somewhat academicThe treatise linking world history with patterns of mineral wealth and exploitation was interestingAnd the writer s did mostly in the final chapters talk about the need to make some fundamental changes in our assumptions about growth

TiesThe effects of depletion take different forms and one may be the economic crisis that is gripping the world system And depletion is not the only problem Mining has a dark side pollution that takes many forms and delivers many conseuences including climate change The world we have been accustomed to so far was based on cheap mineral resources and on the ability of the ecosystem to absorb pollution without generating damage to human beings Both conditions are rapidly disappearing Having thoroughly plundered planet Earth we are entering a new world Bardi draws upon the world's leading minerals experts to offer a compelling glimpse into that new world ahe. full of extremely interesting ominous information

As we dig drill and excavate to unearth the planet's mineral bounty the resources we exploit from ores veins seams and wells are gradually becoming exhausted Mineral treasures that took millions or even billions of years to form are now being suandered in just centuries or sometimes just decades Will there come a time when we actually run out of minerals Debates already soar over how we are going to obtain energy without oil coal and gas But what about the other mineral losses we face Without metals and semiconductors how are we going to keep our industrial system running Without mineral fertilizers and fuels how are we going to produce the food we needUg. Many people have heard of peak oil and are concerned that finite fossil fuels such as oil coal and natural gas cannot support our economy indefinitely But what about metals like copper gold platinum aluminum and others Isn t there just a finite supply of those in the earth s crust as well Do we have to worry about running out of metals Well actually we do although it s complicated than the phrase running out implies This is the topic of Ugo Bardi s clearly written and uite interesting book on minerals and how humans extract them He goes all the way back to the beginning and I mean the VERY beginning explaining how metals came to be found on earth This is not primarily about oil coal and gas but they are included as well one interesting sidelight is his explanation of why fossil fuels can never be naturally formed again even if we wait hundreds of millions of years Bardi goes through the seven common metals of antiuity and shows how metals were used in antiuity through the industrial revolution and down to the present day when we use very exotic and rare metals for computer euipment as well as a lot of renewable technologies But we now also have problems getting phosphorus which is essentially if we are to continue industrial scale agriculture A number of call out sections by other well known authors deal with specific issues such as copper rare earths nickel and zinc the Hubbert model fracking and so forth Bardi does a very good job of explaining the critical role of energy in mining Basically with an unlimited source of cheap energy we can blast into lower and lower uality ores at the extreme he considers the possibility of a universal mining machine which could extract minerals randomly distributed in ordinary dirt A universal mining machine has a number of problems including the vast amounts of energy needed and the vast uantity of waste material created On top of that with the decline of cheap energy and the diminishing supply of ores with rich concentrations of the metals we want it appears that we really are approaching the limits of mineral extraction This poses fundamental problems for the future of humanity it is basically another limits to growth issue

    Many people have heard of “peak oil” and are concerned that finite fossil fuels such as oil coal and natural gas cannot support our economy indefinitely But what about metals like copper gold platinum aluminum and others? Isn’t there just a finite supply of those in the earth’s crust as well? Do we have to worry about “r

    This is a good follow up to Limits to Growth Limits to Growth The 30 Year Update 2052 and other materials from the Club of RomeBardi gives good overview of Peak Oil along with Peak Metals in general and in detail for things such as gold silver copper and uranium On that last one greens like me who are OK with nuclear power as long as wastes are adeuately handled get some food for thought on the depletion of easily mined uranium or
