You can get started with just stuff you have lying around at home and what you can find outside.

Ahh, as a hobbyist amateur Aquascaper I like articles like this.

If anyone wants to learn how to get a great planted tank with minimal maintenance. I suggest Diana Walstad's book "Ecology of the Planted Aquarium". A beginner will easily get amazing success with this method (though it doesn't last forever and a year or two later this will start to break down).

50 Things that Made the Modern Economy is one of my favorite podcasts!

For anyone who finds this article (slash podcast episode) interesting, I'd also recommend the episode on the Hollerith punch card, which is kinda relevant to the history of the computing field :)

I also recommend the author's other podcast "Cautionary Tales". It's very well produced, and fascinating.

How bad was the air back then, was it really so bad that a plant couldn't grow? That notion seems unbelievable.

People literally used to dust soot off their garden plants -- you can see this mentioned in some books. It was not uncommon for visibility in London to be extremely poor due to soot[0]. In fact, this peaked in the 1950's due to the combination of coal burning with automobile emissions[1].

We do this in China.

Other significant western plant hunters who were active in China: https://en.wikipedia.org/wiki/Joseph_Rock https://en.wikipedia.org/wiki/George_Forrest_(botanist) Many were active in China's southwestern region of Yunnan, the origin of tea and camellias.

Now that I think about it, I wiped black road dust from brakes/tires off the windowsills of my drafty street-level SF (Oak Street) apartment every week too. One of the reasons I moved. It doesn't take much.

Lately, I feel like we're living in the Information Age equivalent of this.

Shortly after the Industrial Revolution, society was inundated with all of the new incredibly unhealthy side effects of industrialization. People simply didn't know that those consequences were coming, what their scale would be, or how to handle them. Technology changes much faster than culture, laws, and infrastructure.

Today, we are inundated with disinformation, memes, and a horde of technology trying to take our attention away from our own control. It looks to me as unhealthy and unsustainable as a soot-covered 1850s London or a 1960s 747 packed full of smokers.

It's a scary time to be alive, but I have some optimism that we will figure out how to mitigate the negative consequences of the information world we've created, hopefully in time to deal with the next revolution that follows.

It was sooty enough that the moths evolved to be darker colored, so that they would blend in better with the tree trunks that were darkened by soot.

It could be absolutely dire in the cities. When every house and office is using coal in open fires for heating the consequences are fairly obvious.

According to https://ourworldindata.org/london-air-pollution London had nearly 600 micrograms per cubic metre of particulates in the early C19th. That came with similarly outrageous levels of Sulphur Dioxide, which dissolved in moisture to make it acidic.

Only especially hardy plants could cope with this. Hence the tendency for middle class families to grow aspidistra as a house plant ("keep the aspidistra flying" as George Orwell once wrote) - it was one of the few plants that would tolerate the pollution.

If you wanted to grow anything delicate you did it in a case or somewhere outside London.

Look at how badly polluted US rivers were before environmental protection laws:


OJFord said 7 months ago:

London's nickname 'the big smoke' didn't come about through exaggeration.

While it's a contemporary financial centre, it was much more industrial; with coal-burning factories of all kinds, and shipping, the latterly diesel cranes at the docks were I believe in operation 24/7 for most of their lives.

Not sure it makes the case well, but biology and agriculture being revolutionised by a glass box has parallels.

Don't attack a field directly. Improve it by processes that help all participants.

Part II: Impeachment Is A Diversion And Delay - Blocking of the "impeachment" witnesses was collusion planned before the new year. Listen to an FBI agent's disclosure from Jan 1, 2O2O here. President was to resign late summer securing election for DNC. See latest updates. ||Here is the zip file, which was also made available in the 3Jan2O2O update.

The dialogue about the impeachment starts near the beginning. Having Biden in the White House is as good as Trump or anyone else in their organization. Obviously Schiff and Nadler pledged their allegiance to the organization by raping boys on the record, with their task being to drag out an impeachment designed to obstruct and delay any real efforts to remove the President, thus keeping Trump in power. The witness blocking was to cause an apparent uproar delaying things with legal actions until late Summer. Soon after, the President would resign, leaving any other candidate with not enough time or support to compete with an opportunistic Biden, who is as good as Trump or any other Illuminati friendly politician in the Presidency.

\Wag The Dog: first was feigned impeachment hearings meant to obstruct, now an attack on Iranians in Iraq. Here is what they are trying to distract from & cover up to retain power. $100+ billion in bribes to the highest offices in this country. 815+ deaths from child rapes to prove loyalty!

See the latest PDF updates: FBI Director Wray, AG Barr, SoD Shanahan, & SoS Pompeo each raped boys and were paid billions in bribes for a Soros & Koch funded child rape org. So did Trump & his "impeachment" team Nadler,Schiff,Mueller.So did media moguls Redstone,Murdoch,Moonves. What are they trying to set up? Who can arrest them since they are all bribed and in on it ?

At 1632 Senator Mitch McConnell checks into the Porter camera system inquiring if he can be part of the "eviction" for $10 million dollars. He is informed by group members that there are enough people for the event already and his participation is not necessary. At 1634 McConnell states "I fucked 15 kids, how am I not getting paid by you?" He is dismissed by Donald Reeves with "I think that will be all Mr. McConnell."
