Urea is industrial: mineral gas (methane) + water -> carbon dioxide, carbon monoxide & hydrogen.
Hydrogen + air (nitrogen) -> ammonia
Ammonia + carbon dioxide -> Urea

Yes, that's it. DEF will be industrial as I described.
The synthesis can be reversed in the exhaust-system to produce ammonia (and carbon dioxide). ammonia reduces nitrogen-oxides to dinitrogen and water (harmless).

That means "-can also be produced from other sources, but we haven't researched that much."

There was an interesting series of documentaries on the BBC, called Kill It, Cut it, Use It..

If you're in the UK, you can see clips here, otherwise, many clips are available on YouTube.

Babies of a bird species called the Eurasian Roller vomit a foul-smelling orange liquid on themselves as a defense mechanism. Talk about eau de farum ! LOL

A lot of seabirds vomit on you as a defence mechanism.

Yes, but it seemed extra gross to me to vomit on one's self for this purpose....albeit the alternative is much worse I suppose

I didn't know that birds had abs ;-D

I have to say I don't get all this no true scotsman stuff. Different people have different places of drawing the line as to how much due diligence they can/will do to ensure they are not using any animal products. Add in problems of definition and pretty soon you could get vegans who won't eat any food that has glucose on the grounds that it COULD be from an animal. Doesn't seem very reasonable to start berating people for not being good enough vegans because they use hydrocarbons and sometimes toss a football around.

Nope, not even a vegetarian.

Believe me, I have had enough run-ins with militant vegans to know how fanatical some can get.....when you get accused of being a murderer and life hater; well you get the picture.

I have even been told that some forms of torture are ok; such as feeding veggies only to a pet whose entire makeup, from their teeth to their intestinal constitution are geared for being carniverous. It boggles the mind....

Yes, but most cats, and probably all lizards / snakes, some fish, etc etc. would have difficulties with a fruit and veggie diet. Some of them will literally eat and eat and still not be able to digest the cellulose material in veggies. They starve to death on a strict diet without their meat.

I was once asked:   How can you POSSIBLY eat anything that has eyes?  Andf I asked right back;  "what ?  You don't like potatoes?  ;-)

 

That would be a wrong impression if you are referring to me. However, I do feel that it's rather a negative thing to bash people for not fitting your own personal definition of adherence to a certain philosophy/way of life, and then claim that it was all in good fun and anyone who doesn't think so, or who objects to what you are saying, is uptight, over-serious, consider the topic hallowed ground, etc.

I know your personal definition of adherence to the philosophy of Veganism because you keep talking about what choices people should and should not make.

In so doing, you are both defining your personal definition of adherence to veganism (do these things and not these other things) and attempting to impose your interpretation of veganism on others, by saying that if they don't do things they way you say, they aren't really vegans. So assumption on my part is utterly unnecessary.

An example is when you said :

"Tony Gonzalez of the Falcons is a self-professed Vegan, but really in name only as far as I can see. He's like the married guy (in name only) who won't wear a wedding ring for fear of missing an opportunity.

If Gonzalez doesn't adhere to Vegan principles, he should just call himself a I-Don't-Eat-Meat-But-I-Play-With-Skin guy.

If I was a devout Vegan, I'd pay some REALLY-GIGANTIC-nefarious-type-carnivorous-person(s) to tar and fake-feather Gonzalez.")

And you say *I* went on a rabid diatribe?

I did not go on a "rabid diatribe." I calmly stated my position, as I continue to do now. In addition to being exceedingly condescending, you are making things up which never happened. Please do not do that.

Insults and repeated cries of "You need to lighten up! Don't take things so SERIOUSLY" (all the while rather oddly attempting to deny it) only serve to more effectively make my point for me.

Why?

No, I have not been itching for a fight. I have expressed disagreement with you. These things are not the same.

You have certainly asked for (and indicated hopes for) people to lighten up (sometimes preemptively). To claim otherwise is beyond disingenuous:

>hmmm... I think the big guy could take a little light-hearted fun-poking... lol...IF he cared. ;-)

>I was really hoping a few Vegans would weigh in... unless they're too serious to appreciate the innocuous, light-hearted banter.

>I would definitely consider such individuals "too serious..." for this discourse.

I also get the impression that some members feel this discussion has somehow breached hallowed ground. ;-/

>Clearly, you have difficulty grasping the rhetorical concept of tongue-in-cheek humor.


Please stop calling me names and accusing me of rabid diatribes and tantrums when I've done no such thing. It is very immature.

So if they don't like what you say, they need to lighten up? :\

It is certainly implied.

Now it's *definitely* what you said.

See my reply dated Mar 21, 9:25 PM.

Also, please don't start yelling/cussing at me when I haven't done anything to warrant such a response.

One of us has gotten upset about this conversation and departed from points of logic in their posts. That person is not me. I have generated no drama.

Many vegans will tell you that the only difference between a vegan and a vegetarian is the "reason" for the abstinence: Vegans: so animals will not suffer; vegetarians: for health reasons. The fanatical ones go so far as to not want to destroy a disease harboring misquito....

.

Probably not, anecdotal evidence points to not enough fiber in her diet.

Yes, but a LOT of them prefer animals over humans (until they get eaten by one LOL). This is interesting....nothing but the ORIGINAL LOL

LOL that's only 67 % of them, do the rest abstain? LOL

Yeah, I try to avoid staining my abs too ;-)
