  • Increased blood lead level in children has been correlated with decreases in intelligence, nonverbal reasoning, short-term memory, attention, reading and arithmetic ability, fine motor skills, emotional regulation, and social engagement. … The effect of lead on children's cognitive abilities takes place at very low levels.

    High blood lead levels in adults are also associated with decreases in cognitive performance and with psychiatric symptoms such as depression and anxiety.

  • Carnauba wax is food-safe, but non-abrasive, so it won't smooth the now-etched matte surface, and it's fairly soft, so not very durable. Many car waxes are based on it.

  • When I needed to anodise an aluminium object, I took it to the back door of a medium-sized coating company that serves businesses. I included a note with some relevant information: "no rush, do it when it's easy for you", acceptable range of colours, and my contact info. Took a while, the result was perfect, the price was low.

  • You shouldn’t be paying any form of investor to pretend they can see into the future.

    True, usually index funds outperform active investors, but there are special cases (third point below):https://www.cnbc.com/2020/11/24/heres-when-active-mutual-funds-tend-to-outperform-index-funds.html

    • Investors generally fare better in index mutual funds and exchange-traded funds versus their actively managed counterparts.
    • The average investor pays about five times more to own an active fund relative to an index fund. This makes it tougher for active funds to outperform index funds, after fees.
    • However, the lowest-cost active funds tend to beat the average index fund in categories like junk bonds, foreign stock and global real estate.

    ... A company isn’t affected by whether a fund invests or does not invest in them.

    False. When you buy existing shares, they'll see the increased demand and issue more shares, making more money from investors after you. Same as when you buy a stolen item, the thief reacts to increased demand by stealing another one.

    ... responsible funds are just for show ...

    Those "responsible" ESG-labeled funds (Environmental, Social And Governance) are too lax for modern investors' thirst for good. We need tighter criteria. Commenter Squizzy here said tailored ethical funds exist: https://lemmy.world/comment/15070231

    ... donate the money to charities instead.

    Good, but unsustainable. You can grow charity power by growing money in benefit corporations, such as Mozilla.

  • The activity can be limited, and so can the risk:Once in about 5 years, buy a diversified portfolio of 30 companies in at least 10 countries on at least 2 continents in at least 3 unrelated industries, and forget for 5 years.Maybe prefer to buy in a depression and sell on a bubble if you're feeling extra active. Just be sure to diversify in time by buying at different times to avoid accidentally investing everything on top of a global bubble.

    Between stock sprees, save into a regular savings account.

    Buying shares is easy nowadays through many banks' websites. I use Nordnet.

  • I think the most ethical thing to do is to help the most ethical companies trying to stay clean in a dirty economy.

    Surely there are good-enough ones in all countries and sectors. Makers of wind turbines, solar panels, batteries, cable, bicycles, electric vehicles (trains and trams!), etc. ASML, TSMC, Tuxedo Computers, Fairphone, etc.

  • Maybe all Americans are guilty, but we should blame those who made them that way with lifelong propaganda. Even if you wise up and do your best, tough luck being given FPTP voting and two evils to choose from. How guilty are unwilling participants?

  • The evil of the rich use your money to kill the innocent.

  • Indeed, Wikipedia: Proof of stake # Energy consumption

    In 2021, a study by the University of London found that in general the energy consumption of the proof-of-work based Bitcoin was about a thousand times higher than that of the highest consuming proof-of-stake system that was studied even under the most favorable conditions and that most proof of stake systems cause less energy consumption in most configurations.

    In January 2022, Erik Thedéen, the vice-chair of the European Securities and Markets Authority, called on the EU to ban the PoW model in favor of PoS because of the latter's lower energy consumption.

    Ethereum's switch to proof-of-stake was estimated to have cut its energy use by 99%.

  • Crypto money is a waste of computation that could be used for something productive, like protein folding.

    When investing in (most) companies, the money buys means of production for making a product someone can use. I like that.

  • One day I had my phone charging on the same table I was measuring a liquid from two glass dropper bottles. The phone heard me shaking the bottles, clinking the glass pipettes, and dropping the liquid into water. I’ve never ever talked about dropper bottles as I didn’t know what they are called before this incident. I had bought the liquids with their bottles about a month before, and I’ve only ever referred to them by the brand name of the liquid.

    My Quora feed 20 minutes later:“What are the advantages of using dropper bottles in chemical processes?”
