summary Extracted

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. 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 oresThis is sobering indeed though certainly not on the same level of alarmism as a James Kunstler

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. The science history mythology and economics are all intertwined in the story of how humans extract resources from the planet Plants and animals have been extracting resources since life began but only now do we extract than the replenishment of the resources Going from how early philosopher views of the planet being a giant life form Gaia providing all the resources and helping regenerated the resources once extracted to the actual science behind the resource formation After gravity collected massive rock the heavy resources sank to the core That means that after the formation of the planet to have the variety of resources in the mantle the earth must have been hit by a variety of meteors Many resources created via a cycle in extreme temperatures on the planter while others are biological remnants Given the resources Bardi goes through the history of how the resources were used From tools to weapons to empires and money the nuances and difficulties with extraction and application were provided It took a lot of experimentation to find the proper application of many resources With some regions having resources that other regions want wars broke out A key to all the extraction problems is the energy needed to extract and refine them Going from high grade ore to lower grade ones increases the amount of energy needed to extract the same amount of resources There is a finite amount of resources on the planet but many will still be there for ages to come The extraction of many low grade regions will cost energy than the energy the resources would provide There are many sources from were resources can be extracted such as mines sea fusion space and recycling Mines provide access to high grade deposits The sea contains a variety of resources but separating them would be costly With fusion we have something of a magical machine that creates resources we need from other resources Space rocks have resources but most of the resources we use come from the interaction between living geological and biological formations while space rocks are dead geologically and biologically The resources go into the products we use after using products some of the materials can be recycles again but at cost to both resource function and the amount that can be extracted The sea fusion space and recycling can all help the industrial process continue producing high living standards the problem is that the energy needed to extract resources from those sources currently is or will always be much greater than the energy we get from them Changing production methods to reduce global warming is only part of the problem the planet it is facing The way humans live will drastically change to the resource contrast on production With less production maybe pollution and greenhouses gasses will be less of a problem but humans will still face drastic changes The author has a chapter on a variety of ways to measure the depletion of resources some of which have failed while other successful Although many models have been wrong it does not decrease the importance of the fact that depletion is unavoidable due to the limited supply of resources The models allow industries and people to prepare to adapt to either substitutes or limiting their use of the deleted resource One problem this book has is with economics The author claims that many governments and corporations want to grow Rather than focus on growth we should be focusing on sustaining for we cannot grow forever with the limited resources we have The problem is that wealth does not reuire extraction resources There is no reuirement for wealth producing products to be tangible Intangible services are part of the production process as well Although we will need to extract resources to maintain the social structure there will be less pressure to produce tangible products that are resource intensiveThe book is heavy with science and statistics but the author writes with a prose that is easy to read without degrading the complicity of the issues Each chapter provides articles that are tangent to the story but provide a different view of the concept under discussion These glimpses not only help make the topic understandable they also go deeper into a particular topic The author does claim that humans can adapt but adaption has a variety of limitations Even through each resource can be used productively such as using less of the resources per product that is not enough to prevent major changes in society

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. A very sobering view of the state of the state of mineral mining and global supply The world is rapidly running out of key manufacturing minerals with many estimates reaching little or no supply by 2050 to 2100 Nickel Copper Magnesium Phosphorous Zinc etc all have limited resource such that the cost of extraction becomes higher and higher over time At some point the world will be forced to attempt to recycle much of these critical elements but with diminishing returns Bardi shows that there is no real answer over time and creative solutions will have to be developed Again the future seems bleak to these types of issues

    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

    “Everything we use after all if not grown must be mined” Europe entered the Middle Ages badly depleted in minerals “black powder” from China soon restarted European mining Iron needs to be turned into steel which is an alloy

    This book will make you rethink everything around you It talks of mining and depletion and it's really horrible to see what we've done and are still doing to the planet It clears up a lot of things for instance it talks about what f

    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
