🧵 THREAD N°17 : #blockchain et #environnement

La blockchain est régulièrement pointée du doigt pour son impact environnemental, certains allant jusqu'à dire qu'il faut bannir les cryptos.

Mais qu'en est-il vraiment ? Peut-on trouver d'autres solutions ? Une intro au débat 👇 Image
1/ Il faut d'abord comprendre ce qui pollue dans l'utilisation des #cryptos.

Comme vous le savez, au sein d'une #blockchain, les blocs doivent être validés. Pour cela, des mineurs doivent résoudre un problème cryptographique qui permet de s'assurer de l'inviolabilité des données
2/ La plupart du temps, le problème à résoudre est un problème de #ProofOfWork avec lequel les mineurs doivent essayer des millions de combinaisons en quelques minutes jusqu'à trouver la bonne (pour faire simple).

Le premier à résoudre le problème reçoit une récompense.

Thanks to @GeoffCutmore & @cnbcKaren for having me on the show this morning.

Here's a short thread of the notes - entitled, "Time to Get Real?" - which I put together in preparation.
They should hopefully be self-explanatory:-

#SquawkBox #CNBC #macro #equities #commodities
You've heard it here before: pay out or pay down is a big part of the #inflation equation:-
Yes, there's a "V" - or at least a flipped square root sign - underway, but will it extend far enough & fast enough?

Re-watching some shows while #socialdistancing for #MarchBreak? We're chatting this week about some of our favourites that have great #geology or interesting stories behind their #filminglocations.

#GameofThrones used #Iceland's #Thingvellir Park as the #BloodyGate. Its landscape is caused by the Eurasian and #NorthAmerican tectonic plates meeting there and pulling apart at a rate of 2 cms per year. This made a rift valley: low land between 2 separating continents.
#nspoli ImageImageImageImage
#MagheramorneQuarry, #NorthernIreland, is the set for #CastleBlack and #TheWall in #GameofThrones. The quarry wall is used as a backdrop and effects make it look huge.
The site's limestone was used to make cement. #NS has a limestone quarry and cement plant in Brookfield.

Former #mines and #quarries often become parks and protected areas. This thread shows some examples in #Halifax, #Dartmouth, #Shelbourne, #Truro, #LunenburgCounty and #KemptShore.

#nspoli #cbpoli #NovaScotia #NS #mining #reclamation ImageImageImageImage
#KiwanisPark in #Truro was developed as a gravel pit in the 1930s to help build Route 2. Like a lot of former pits and #quarries, the site has filled with water and become a natural oasis in the heart of the town.
#nspoli #cbpoli #novascotia #NS #mining #reclamation @TownofTruro Image
Former mines and quarries are often hidden in plain view! #PointPleasantPark contains 50+ former quarries. The stone was used to build walls and forts in the park. For example, slate from the #QuarryPond helped build the #MartelloTower.

New #mines are often found next to old mines - historical sites worked with basic tools and little science can today be mined profitably and environmentally-responsibly with heavy equipment and sophisticated science and engineering.
#nspoli #NovaScotia #NS #minerals #geology #CB Image
At the #MooseRiver #gold mine, tailings from a century ago are being remediated by modern #mining. Historic tailings are dug up and placed in a special cell in the mine's #tailings facility to contain them and ensure they don't continue interacting with the environment.
#nspoli ImageImage
This wood is century-old cribbing - support for an historic shaft at the #MooseRiver #gold mine. Modern #mines often find neat evidence of historical #mining like old tunnels, tools and wood. Mines today can also fix issues with #subsidence or #tailings at historic mines.

This is the anticline at the #MooseRiver #gold mine. It was formed by the collision of #NorthAmerica and #NorthAfrica 325 million years ago. Layers of horizontal sedimentary rock were crumpled into #anticlines (domes) and #synclines (troughs) - a series of rock waves.
#nspoli #NS ImageImageImage
The #Anticline hosts the Touquoy #gold deposit. Its domes trapped melted, gold-containing rock as it rose from deep in #earth's crust. It flowed into fractures in the rock, creating quartz veins with gold. There are also tiny disseminated particles of gold throughout.
#nspoli #NS ImageImage
The #MooseRiver #gold mine is the first in a series of proposed gold #mines along the #EasternShore. About 300 people work there and the other mines would create 100s more jobs for #NovaScotians.
#Mining employs 5500 in #NS and is the highest-paying #resource industry.

#Mining built #NS!
The #Amherst Red Stone #Quarry was on James Donalds' farm, east of Willow St. (1889-1914). It provided #sandstone for many Amherst heritage buildings including Bank of #NovaScotia (built 1907), Trinity-St. Stephen’s (1906) and 1st Baptist Church (1895).
#nspoli ImageImageImage
"Busy #Amherst" grew rapidly after the #IntercolonialRailway was built through town in 1876 and with the growth of industries like #coal #mining, transforming it from a village to a bustling industrial town. Many of its beautiful buildings date from that era.
#nspoli #NovaScotia ImageImage
Today, the #Amherst Red Stone #Quarry is a lovely pond in a field. Former #mines and #quarries are often hidden in plain sight!

FACTS ABOUT GOLD AND THE ENVIRONMENT
#Gold #mining is bringing 100s of millions of $ in investment to #NovaScotia and creating 100s of jobs for #NovaScotians.
Modern mining is a sophisticated science-based activity that takes proper care of the enviro.
#nspoli Image
@Guysboro #Reclamation - Before getting operating permits, #NovaScotia #mining companies must get government approval of reclamation plans and post reclamation bonds that ensure funds are available to properly take care of sites.
#nspoli #NS #minerals #geology Image
@Guysboro Water Management: Mine operators are required to treat, strictly monitor and test water, and report to @nsgov. Water is usually recycled on-site. Water released back into a river or lake is usually cleaner after it has been used in a mine or quarry than it was beforehand.

Many #NovaScotia #mines/#quarries in the 1800s used tramways (horse-drawn wagons on rails) to transport rock. They were ancestors to our first railways because they showed the advantage of steel rails (instead of wood) and gave a platform for early locomotive experiments.
#nspoli Image
#NovaScotia's first railway (meaning it was powered by steam, not horses) was the Albion Mines Railway in Stellarton, built in 1839 to haul coal from the #Stellarton mines to docks in #Pictou Harbour. It was only the second steam railway in Canada. It operated until 1961.
#nspoli Image
Samson, the oldest locomotive in Canada, was 1 of the iron horses imported from England in 1839 to haul Albion Mines trains. Retired in 1883, it was displayed at Chicago's World Fair, in Baltimore, #Halifax and #NewGlasgow. Today it's at the Stellarton Museum of Industry.

MINING AND QUARRYING #LABOURDAY FACTS

Today’s #mining and #quarrying industry is a sophisticated, science-based business that provides essential materials we all use every day – and a very different industry than in the past.
#nspoli #NovaScotia #NS #minerals #geology Image
#Mining/#quarrying employs 5500 #NovaScotians and generates $420 million per year in economic activity.
97% of jobs at #NovaScotia #mines and #quarries are filled by Nova Scotians. The industry is committed to hiring locally.
#nspoli #NS #minerals #geology #labourday Image
#Mining is #NovaScotia’s highest-paying resource industry. Its average wage is over $55,000 per year – on par with the province’s financial services sector - and an entry-level job like haul truck driver pays an average of $25 per hour.

From today on #coal #mines will be history in #Asturias. Mining got to be the region’s main industry with 50.000 employees and 10.000 km of underground galleries. Some of them could remain open if they explore uses not linked to coal. Part 1 of a #mojo story x @asturiassemanal
Part 2 of a #mojo story about #Sotón #mine. It stop mining coal in 2014 and open for visitors. Last june it hosted a #race at 500 m. depth to show there is future for mines not linked to coal. In @RTPAOficial we reenacted the race with 2 miners to talk about the future of mining.
And part 3 (last). This #mojo story was shot on an iPhone X and a light gear: @Shoulderpod X1, @SennheiserUSA mic & @manfrotto_tweet Lumimuse light.@FiLMiCPro as filming app. Edit with @Adobepremier, subtitles with @LumaTouch. Stock footage from the race, shot & owned by Hunosa.
