Trovare il rimedio a questa situazione non è facile, semplicemente bisognerebbe aumentare la produzione investendo nella ricerca di nuove miniere, visto che secondo le stime fatte dalla US Geological Survey nel 2015 3,5 miliardi di tonnellate metriche non sono state ancora scoperte contro i 2,1 miliardi già esplorate.

By eleven o’clock the next day we were well upon our way to the old English capital. Holmes had been buried in the morning papers all the way down, but after we had passed the Hampshire border he threw them down and began to admire the scenery. It was an ideal spring day, a light blue sky, flecked with little fleecy white clouds drifting across from west to east. The sun was shining very brightly, and yet there was an exhilarating nip in the air, which set an edge to a man’s energy. All over the countryside, away to the rolling hills around Aldershot, the little red and grey roofs of the farm-steadings peeped out from amid the light green of the new foliage. “Are they not fresh and beautiful?” I cried with all the enthusiasm of a man fresh from the fogs of Baker Street. But Holmes shook his head gravely. “Do you know, Watson,” said he, “that it is one of the curses of a mind with a turn like mine that I must look at everything with reference to my own special subject. You look at these scattered houses, and you are impressed by their beauty. I look at them, and the only thought which comes to me is a feeling of their isolation and of the impunity with which crime may be committed there.” “Good heavens!” I cried. “Who would associate crime with these dear old homesteads?” “They always fill me with a certain horror. It is my belief, Watson, founded upon my experience, that the lowest and vilest alleys in London do not present a more dreadful record of sin than does the smiling and beautiful countryside.” “You horrify me!” “But the reason is very obvious. The pressure of public opinion can do in the town what the law cannot accomplish. There is no lane so vile that the scream of a tortured child, or the thud of a drunkard’s blow, does not beget sympathy and indignation among the neighbours, and then the whole machinery of justice is ever so close that a word of complaint can set it going, and there is but a step between the crime and the dock. But look at these lonely houses, each in its own fields, filled for the most part with poor ignorant folk who know little of the law. Think of the deeds of hellish cruelty, the hidden wickedness which may go on, year in, year out, in such places, and none the wiser.

One of the things that concern me is copper. So we need about 4.3 billion tons of copper for the first generation of electrical, non-renewable technology systems. Including everything's stitched together. So 4.3 billion tons. 01:04:25 Nate Hagens: And if we relax your assumption of four weeks of buffer and that we have some hybrid system of depleting fossil fuels with some renewables, that 4.3 billion tons could be relaxed to 3.3 or 2.2 billion tons? Simon Michaux: I think it's 2.2 billion tons. It substantially does reduce. However, we are producing for copper say 24 million tons a year now. 01:04:53 So we've got to run at 180 years to hit that point. So existing at- Nate Hagens: It's not going to happen. It's not going to happen. And here's the other thing, and I'm sorry to interrupt. But Olivia Lazard is going to be on this show in a few weeks and her work is the countries where this stuff comes from. 01:05:17 And not only are they war-torn and have inequality issues, but there are also many of the countries that are going to be influenced dramatically in the near term from higher wet bulb risk to humans climate impacts. And we won't even be able to extract in these countries because of social and environmental 01:05:45 reasons. I can send you some info on that. Simon Michaux: Yes, please. But these are the things we need to get our arms around. So our copper reserves at the moment are at 880 million tons. Now existing growth, that's according to the USGS, US Geological Survey. So prior to 2020, humanity mined 700 million tons of copper back to 4,000 BC. 01:06:10 And that sounds like a lot. But to keep up with copper growth, copper demand growth, just the way we are now without electrifying, we will do the same in the next 22 years. So the last 4,000 years will be compressed into 22 years to keep up with the economic growth as it's increasing. And so the first generation, let's say the 4.3 billion tons is correct. 01:06:33 That is 6.2 times the historical mining rate back to 4,000 BC. So if we are right and we can shrink that buffer down, we are still three times the historical rate. Nate Hagens: Not the historical rate. The historical total cumulative

here are those same numbers compared 00:41:21 against reported global reserves so there's the amount of metal we need and there is the global reserves this column is the proportion of metals required to 00:41:33 phase out fossil fuels as a percentage that is of all the copper we need to make one generation of units current global reserves will get us 19.23 00:41:45 of the way there we don't have enough copper for one generation

current plans are not large enough in scope the task before us is much larger than the current paradigm allows for

Chile has developed from 1990 to date, a considerable decrease in poverty rates, which fell from 40.5% in 1990 to 8.5% in 2015.

Between 1990 and 2016, copper mining provided on average of 7.8% of tax revenue for Chile

Due to its electrical conductivity, copper is used in electronics, cars, and wires. This makes copper critical for highly developed countries.

Developing economies’ copper demand has steadily grown over the last decades, fueling economic and social improvement. By 2011, China already represented 40% of the demand.

Codelco is a state-owned Chilean mining company and the world’s largest copper producer. Based on their annual report and USGS statistics, they produced ~10% of the world’s copper in 2015 and own 8% of global reserves. They are also a large producer of greenhouse gas emissions. Last year, Codelco produced 3,2 t CO2e/millions tmf from both indirect and direct effects, and in 2011 it consumed 12% of the total national electricity supply.

Copper is a key driver of growth and economic wealth for Chile.

copper mining significantly contributes to climate change.

Shaida’s mineralisation has been described as a porphyry copper deposit.

The Shaida Copper Mine is situated in the western region of Afghanistan in the Adraskan District of the Herat province, 65 km South-West of the city of Herat and 50 km SSW of Gozareh

Monseigneur de Hemptinne watched Yeke people working at Dikuluwe as late as 1924. They worked in the dry season and stopped when the first rains arrived. The mining camp was near a stream where millet could be planted. Women and children collected malachite from the surface, while men used iron picks to excavate pits and shafts, using fire to crack the rocks when needed. The mines were between 10 metres (33 ft) and 15 metres (49 ft) deep with galleries up to 20 metres (66 ft) long. The ore would be sorted and then taken to a nearby stream for concentration before being smelted

The Katanga, or Shaba, copperbelt in the DRC is a belt about 70 kilometres (43 mi) wide and 250 kilometres (160 mi) long

his is the second round of mineral licensing conducted by the Afghan government, which in 2008 gave Metallurgical Corp of China rights to the Aynak copper deposit
