Well weathering of plastic will release some CO2.

What I mean really is that plastic is made from a waste product and very little CO2 is emitted in its production. It displaces more carbon intensive material use, and when its buried any carbon it contains is sequestered. It’s a great material that way if properly disposed of.

You seem to not have read my entire comment. CROWN Acts only exist in 14 states, meaning most of the country can still discriminate based on hair. Try again.

it's a chemical and materials company really and some of their products are very effective. Their earplugs the military (US) used for some years ended up not performing to spec and leaving many service members with permanent hearing damage.

the company is huge and holds a lot of patents. they are not a cheap knockoff producer if that's what you mean.

Yes, I know all this. I just don't think conforming is going to cure it ESPECIALLY in this day and age when things like the CROWN Act exists. I also think it needs to extend to everyone. So many jobs will discriminate against men with long hair for example. But you're right, even then people will still be bias and hair discrimination is hard to prove unless they specifically mention it. The only true way to solve this would be "blind" hiring, where employers don't see what the candidate looks like. I believe orchestras already do this because the bias against female performers is so heavy.

I also don't think the ONLY reason people use relaxers and whatnot is for jobs. The entire expectation to conform should be shunned imo

All races are equal in value, but hair types are observably not the same.

No, but hair discrimination STILL EXISTS today. Did you know that only 14 states in the US have laws (often known as the CROWN Act) that officially ban discrimination against natural hairstyles and 15 more are even considering passing CROWN Act legislation?

Even then, unconscious bias is still going to exist. There are still going to be hiring managers who don't perceive natural hair in Black women as being "professional" or even attractive. That is going to influence who they hire and they may pass a Black woman with natural hair for a Black woman with chemically straightened hair.

Our actions don't exist in a vacuum, and you cannot pretend that there will be no residual effects from centuries of discrimination just because legislation is passed.

Oh interesting, at least they wear masks. I always figured the fumes would be worse, but I didn't realize there was that much grinding.

wrong. Lamps that emit ultraviolet (UV) radiation are standard in some nail salons to speed-dry regular manicures and to set gel manicures. These lamps can be called UV lamps or LED lamps and both emit UV radiation, predominantly UVA rays which have been linked to increased risk of skin cancer

Sure, but it's not 1950 anymore. Show me a corporate work space that hires white people with dreadlocks and I'll show you 50 with black people sporting dreads.

Plastic is technically recyclable, but practically, it's not. Food and medical plastic can not use recycled plastic ( recycled plastic is not sterile). That's a huge part of the plastic market. There are a lot of different plastics in the market. Mixing the types of plastic makes it unrecyclable. Colored plastic of the same type can not be mixed. Most of this can be solved with manual sorting, but that is labor intensive (expensive), and the end goal is not to recycle the plastic waste stream, but to cherry pick the stream as it feeds into the incinerator.

I wouldn't say plastic is a CO2 sink. Being a sink makes it sound like CO2 was pulled from the air to make the plastic, and then it was buried. Burying plastic just keeps it from causing a lot of trouble that burning it or dumping in the ocean causes.

Like acetone? Production workers at small paint companies (where ventilation isn't nearly as good as compared to medium and large companies) are probably exposed to solvent concentrations - including formaldehyde - at least two orders of magnitude higher than salon workers.
