Why do you have that preference? It's my understanding that the alternatives are worse.

Organic food is worse than food wich was treated with various chemicals to kill living things? Thats news to me. But you probably mean "alternatives" for producing dirt cheap. Then yes, there are much worse substances around. Doesn't make it good, though.

No, I mean that the chemicals used in organic farming to kill living things are more harmful to humans than glyphosate is.

Or the staggering number of anti-GMO laws and business ad campaigns.

GMO are a very powerful technology. Like anything powerful, an intelligent person calls for caution. A lot of people are worrying about GMO in food because we don't have enough data about them. We are changing things that could have important biological, health and ecological impacts, but the companies producing them are not willing to test them extensively for safety during 20 years before selling them. We don't kno…

This is exactly the kind of misinformation being described above.

Why would "traditional" crops going through random mutations be any safer than GMO crops going through highly controlled, highly tested mutations?

It isn't a mysterious process - it's science. It allows us to create products like Golden Rice to alleviate malnutrition and increase crop yields. It's probably the only thing which has helped curtail world hunger in any meaningful capacity.

"The new synthetic diamonds will come in pink, blue and white, and the stones will contain a tiny Lightbox logo. De Beers said the logo won't be visible to the naked eye, but it will make the stones easily identifiable as lab-grown."

So de beers will intentionally damage their synthetic diamonds. Sure I wanna buy synthetic diamonds from you guys.

There was a an engineer several years ago developing a process to create large sheets of diamond. He claims to have received numerous death threats.

Was he related to this? http://www.innovations-report.com/html/reports/life-sciences... https://en.wikipedia.org/wiki/File:Single-crystal_CVD_diamon...

Don’t think so. It was a guy in the USA, about 10 years ago. Though looks like many are doing it now with CVD. Diamond semiconductors are the holy grail, though there is current work growing diamond heat spreaders directly under GaN active regions.

THIS IS NOT ABOUT MAN-MADE DIAMONDS! Read this article: https://www.thestar.com/business/2018/05/29/de-beers-to-sell... Read the last paragraph: The move also comes at a sensitive time for De Beers and its relationship with Botswana, the source of three-quarters of its diamonds. The two have a sales agreement that gives De Beers the right to market and sell the diamonds from Botswana. The deal, which gives De Beers i…

Good? If the acceptable price paid for diamonds in both the wholesale and retail markets is lowered, then the pressure to mine diamonds (and the attendant violence & natural damage) should be lowered as well. That seems like a good outcome? Additionally, DeBeers is unlikely to be able to dominate the lab-grown market so this step should legitimize lab-grown stones with little risk of creating another monopoly.

Educated people who hate GMO are instant signal that they don’t understand science. A good filter

I don't necessarily hate all GMO but I'm very dubious about GMO crops that are engineered to withstand Glyphosate better and I prefer not to eat such crops because they are more likely to have been treated with this herbicide.

Actually, they use just as much glyphosate when growing wheat (not GMO) as when growing corn (maybe 80% is GMO) in the US.

    USA
    corn
      production     333 000 000 tons
      glyphosate use  69 000 000 lb
    wheat
      production      58 000 000 tons
      glyphosate use  17 000 000 lb

"Lightbox will transform the lab-grown diamond sector by offering consumers a lab-grown product they have told us they want but aren't getting: affordable fashion jewelry that may not be forever, but is perfect for right now" This is clearly a play to devalue the image of man made diamonds. "May not be forever" my ass, it's the exact same thing. Their goal is probably to try to quickly drive the price of man made dia…

I'd love for synthetic diamond to bring the price down on gemstones. A lot of people are engaged in arduous and risky work to produce natural stones. The environmental costs, too, are real. Modern high-quality synthetic materials, whether in gemstones or other uses, have so much to offer in fashion innovation. Indeed, diamond jewelers claim that silicon carbide (SiC) has "excess fire" as it has greater dispersion tha…

> Indeed, diamond jewelers claim that silicon carbide (SiC) has "excess fire" as it has greater dispersion than diamond. SiC has a greater index of refraction, which improves the properties of total-internal-reflection as well!

As an investor you probably know this, but for the benefit of everyone else, Moissanite is a marketing term for (crystalline) silicon carbide.

Similarly to how sapphire is a special term for crystalline aluminum oxide, but the word "sapphire" has a bit more tradition behind it.

Farmer here: We apply glyphosate to both GMO (roundup ready) and non-GMO crops. The big difference is when: The roundup ready crops can have it applied early in the growing season. The non-GMO crops have to wait until just before harvest, when you don't care, or even prefer, that the crop dies.

Organic food IS food which is treated with various chemicals to kill living things. But the list of various chemicals are arbitrarily defined as "natural", putting them in the same list as other safe, natural chemicals like ricin, botulinum, strychnine, arsenic...

"Organic" is a marketing term, not a descriptor of the production process.
