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. 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 fracking is and why modern fracking is much dangerous than fracking was a few decades ago It also talks about some solutions to the problems of depletion It was really depressing but tried to be uplifting at times which is hard to do because it seems that the depletion problem is pretty obvious but instead of conserving resources we are using them up faster than ever There was a little too much talk of models for my taste because they would describe a model and then say how it didn t actually apply to the real world because it didn t account for a lot of other factors If a model doesn t apply to the real world I m not sure why they would talk about it I thought it was much effective when they just showed data This is a problem that Nicolas Nassim Taleb talks about in his book the Black Swan why use a model that has no bearing on real life Additionally a lot of the first part of the book was about history and gold trading in the Roman Empire and I felt that it wasn t that relevant to the subject at times and this might dissuade readers from getting to the actual meat of the book when it talks about depletion and modern mining I enjoyed all the small side essays included but I m not sure why they didn t just make them part of the main text At times they were actually interesting and informative than the main text as they applied to specific subjects such as the difficulty of replacing all gasoline cars with electric cars in terms of the resources needed I thought this book was extremely informative and should be read by everyone in order to effect change on a larger scale In particular politicians and those in charge of policy should be reuired to read this as it really clears up a lot of issues and looks at depletion from an objective point of view rather than a political one If you don t feel up to reading the whole book just skip the sections on history but in a perfect world everyone would read this book Cenote ve done and are still doing to the planet It clears up a lot of things for instance it talks about what fracking is and why modern fracking is much dangerous than fracking was a few decades ago It also talks about some solutions to the problems of depletion It was really depressing but tried to be uplifting at times which is hard to do because it seems that the depletion problem is pretty obvious but instead of conserving resources we are using them up faster than ever There was a little too much talk of models for my taste because they would describe a model and then say how it didn t actually apply to the real world because it didn t account for a lot of other factors If a model doesn t apply to the real world I m not sure why they would talk about it I thought it was much effective when they just showed data This is a problem that Nicolas Nassim Taleb talks about in his book the Black Swan why use a model that has no bearing on real life Additionally a lot of the first part of the book was about history and gold trading in the Roman Empire and I felt that it wasn t that relevant to the subject at times and this might dissuade readers from getting to the actual meat of the book when it talks about depletion and modern mining I enjoyed all the small side essays included but I m not sure why they didn t just make them part of the main text At times they were actually interesting and informative than the main text as they applied to specific subjects such as the difficulty of replacing all gasoline cars with electric cars in terms of the resources needed I thought this book was extremely informative and should be read by everyone in order to effect change on a larger scale In particular politicians and those in charge of policy should be reuired to read this as it really clears up a lot of issues and looks at depletion from an objective point of Sottomissione view rather than a political one If you don t feel up to reading the whole book just skip the sections on history but in a perfect world everyone would read this book

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. 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 of Iron and Carbon Damascus blades were high carbon steel actually made in India Coal coming from England changed the smelting game with coal fired furnaces replacing small charcoal ones Coal meant you could have everyday objects finally made of metal In ancient history there was little reason for wars and conuest your fertile valley gave you what you wanted However once precious metals arrived on the scene that changed Now there was a reason to go somewhere to plunder Kings wearing gold soon became propaganda a symbol of what your kingdom could achieve Drier southern Italy lacked waterways and couldn t industrialize as fast The struggle for world domination was won when Britain played a trump card in the game coal With its abundant coal resources Britain could produce plenty of iron for cannons With her powerfully armed fleet Britain could get timber from anywhere British coal production peaked around 1917 In the 70 s planners saw that the US oil had peaked and the US was about to imitate Britain s post peak coal decline This lead to the present Middle East policy of US prime access at all costs to Middle East energy 60% of all nickel is used in stainless steel 50% of zinc is used for galvanizing Fracked gas has a worse global warming impact than coal A severe problem no one talks about is phosphorus depletion in agriculture there are no substitutes for phosphorus Eight million people are said to have died at just one silver mining site Cerro Rico near Potosi Bolivia Some areas of the earth could become too hot for humans to survive Whether we will be able to live on this new planet will be impossible to say The only way out of our predicament is to embrace change instead of fighting it Ugo s list of the world s biggest problems is climate change peak oil population and mineral depletion I would add capitalism and its focus on short term gains and externalizing all costs Ugo ends reminding us of thinking about our fossil fueled choices As it stands now SUV s and vacations to Hawaii by plane we need to pause and reconsider That approach is simply not workable Technology cannot change the laws of physics

    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” imp
