This is dark. I will never understand how so many educated people have such an anti-humanist view of the world. Humans are awesome, intelligence is awesome. More humans means more amazing things. We are capable as a species of incredible things, and we have the ability to save our planet as well as continuing to grow. We cannot outgrow this planet and colonize other worlds, we cannot solve climate change, nuclear fus…

Some People just dont like other people because they think other people dont like them because they dont like themselfs. Yes you read that right.

Psychologiy is a fidgedty beast and in a socicety that is fed by automated media bots and optimized for the "most bang for the buck".

While we long for educated and helpfull people, we have only recently actually began to accept nerds.

So this trend has been going on for a while now, I looked a bit into it about 5 years ago here's what I found: - Tons of popular and legal products/chemicals are "endocrine disruptors"[1] (fancy term for mess with hormones). - The FDA/EPA doesn't deny that, they don't themselves even really require tests for long-term health effects in humans (too difficult). Instead they give animals a 1000x+ dose and look for immed…

Did you make any lifestyle changes after your research?

I've heard on a few podcasts that this is how European countries do this. We need to stop letting for-profit companies gamble with the health and longevity of the species in the interest of profits.

The species that mutilates and heats the planet, and which created those companies? This may be a long-overdue self-correction. Global infertility may just be what solves global warming.

You're welcome to properly end your own fertility at any time. I quite like humans.

There's so much to unpack here, I'd love to have a longer form discussion in a place where we won't run out of thread depth, but I can't dig into all of the points in this format. This all gets very philosophical, but seriously, optimism is much better than pessimism here. > There are awesome things on earth besides humans Like what? Nature is cool, we shouldn't destroy it, but nothing else is truly sentient on this…

> nothing else is truly sentient on this planet besides us

This is definitionally wrong. Sentient merely means "having sensations" or even the weaker having "senses". Perhaps you mean "sapient", with reasoning, self-knowledge, and an "internal life".

This too would be wrong, but not as obviously so. When we actually try to look and measure other animals fairly, we generally find that in measures of cognitive capability, there are animals that are not that different from humans. Many animals pass the mirror test. There are birds with complex vocal languages. Both apes and birds have been recorded spreading adaptions in food preparation within a cohort and down generations (the two astounding cases are dealing with the toxic backs of cane-toads in Australia -- learning to flip them over and only eat through the stomach (corvids) and picking them up and washing them (ibises)).

You also have the opposite problem, where things we think we're good at, even ones some would say define us as a species, are actually pretty poorly done by many of us. GPT-2, which is clearly not sapient, and only capable of writing a terrible, meandering essay, still does better than many high-school students, or even college students. And we now have much better examples, that still clearly aren't sapient.

Yeah, I feel like the soy myth has been disproven time and time again but won’t die already. This and seed oils get hit with the exact same playbook, then disregard significant chunks of the world that have zero issues with them.

I haven’t found anything compelling about seed oils being awful, but I haven’t found anything indicating that we should actually eat them, though. Have you? I’m asking sincerely. It seems to me like they’re better than some alternatives if only to reduce saturated fat intake, but generally speaking, if any refined fat is avoided it’s probably to your benefit. I often wonder if people think seed oils are bad because t…

Canola oil in particular seems most interesting. Its nutrient composition is more impressive than olive oil.

As for your theory, seed oils only make up 7% of US diet calories. Saturated fat makes up more than twice that. Replacing saturated fat with canola seems like an uncontroversial outcome improvement.

“men who are overweight tend to have reduced sperm concentration, lower total sperm count, and fewer motile sperm. … The fact that the sperm count decline is also occurring in countries in South and Central America, Africa, and Asia, according to the new meta-analysis, suggests that the lifestyle factors and environmental exposures that are likely to blame are present globally“

While the article does not rule out chemical contributions, this strongly suggests a lifestyle effect since these regions have been moving out of the poverty trap for over 30 years. Perhaps that is also what makes the sperm decline seem to accelerate. So behind yet another environmental scare might actually be good news: Wealth also comes with a higher rate of obesity and the tendency to do office work where a male would be sitting on a chair all day (increasing the temperature the scrotum is exposed to).

One thing that I'm genuinely curious about that I've never heard addressed is whether the large increase of people identifying as trans(trans women in particular) could be related to the same factors that are causing lowered sperm counts and testosterone in men. There are massive amounts of compounds in our environment that are endocrine disrupters or mimic sex hormones like estrogen. Like maybe many persons assumed…

This is joe rogan level speculative nonsense.

To be fair, so is your dismissive statement in calling it nonsense. Maybe expand on that? I for one have thought the same thing many times and am finding the conversation here quite interesting.

there are growing studies about 1) the connection between gut biome damage and obesity and 2) that chemicals in food and products are destroying our gut biome. Putting those two things together, these signals in the article would make sense.

The thesis of the book 'Countdown' is that this is largely due to widespread plastic and other endocrine disrupting chemicals. I believe this is one of the most important risks to humanity, after climate change, and global war. So far, I've taken some lifestyle changes to combat this: 1) Threw out all of my teflon cooking pans 2) Refuse to consume food in heated plastics 3) Throw out teabags (they have plastics). Use…

I'm fascinated by this. I think the desire to make the necessary lifestyle changes is there, but I question the practicality. I want to have my foods and beverages untouched by plastics, but how realistic is this currently? I want to buy bread that's not wrapped in plastic. Is the alternative really to make your own? Even then, can you ensure the ingredients you're sourcing for your own bread starter for example, als…

Get a bread machine and then its pretty straight forward to make your own.

As someone who is too lazy to do their own research on this topic....did you happen to find which products generally contain the most endocrine disruptors?

My partner and I recently embarked on a journey to replace as many products in our lives that contain endocrine disrupting chemicals (EDC's) as we could. It's _really_ hard. You have to carefully read product labels, 99.9% of products don't contain any info about EDC's, you have to specially seek out ones that are labeled as phthalate-free, BPA-free, etc. Biggest offenders are in the kitchen and bathroom. Shampoo, co…

I’m horribly allergic to most perfumes. Nothing scented: no soap, shampoo, nothing.

So do I get super sperm or something?
