I can't recommend this highly enough if you're never planning on having a kid or if you're done having kids. I am a huge weenie when it comes to medical procedures and mine was super simple. I was sore for a few days, did my follow up, and that was it.

I still use condoms because of STDs but I never have to worry about accidentally having a kid if a condom breaks.

Just use the washable ones, made from organic cotton. Lower environmental impact, shorter time until potty trained as well on average. Still not as good as not putting extra people on the planet though 😁

Styrene is in the vynal family, Styrene-Isoprene-Styrene is used to make extremely expensive surgical gloves so I'm going to say yes.

"So after a million years of putting off adjustment maintenance, the size of the sun has grown to critical levels and it is now too late. We will be evacuating at the next solar system in 120 [MINUS FIVE] years and diverting all available resources to emergency maintenance in the mean time. This announcement is a recording." Frickin' humans, eons of progress and can't even do eons of progress right.

We didn't find anything about Nirtrile and protection. Could you clarify?

I don't think so. But I think that that's going to vary a lot based on how you want to measure "badness for the climate".

My instinct is to look at Feed to Gain Ratio, which is the measure of food eaten to weight gained. This will vary animal to animal based on the animal's purpose (meat cows vs dairy cows, meat lambs vs wool sheep, etc) and the type of food they're fed.

Still, there are reliable bands for estimating for each animal. According to This Article, it looks like sheep can fall into a 4:1 to 6:1 ratio while cows are closer to 12:1 (this is a bit higher than I was taught in high school biology, but not by much). Of course, the higher these numbers, the "worse" the animal is for the environment.

About as bad as any of the animals that can eat grass, wild or farmed
