I don't think they use these two particular things, but different countries have different Standards.
If you want to go that route, they also use tractors or other machinery using oil in some capacity.
There are fertilizers without oil production, it's just not scaleable in comparison and fell out of favor due to other stuff.
But organic products without these kinds of fertilizers exist.
I remember a 'not just bikes' video on which he showed a video from the 80-90s that was literally this setup: a teenager suddenly has to live without oil products, and they pick specific large impact things to get the pre determined result: the teenager is happy for all the oil products.
Yes, we are using it for a lot of different things. A lot of industries just don't want to find some large scale replacement, because why would they without incentives.
We do have alternatives for a lot of things, just not mass produced or optimized.
The goal should not be to get rid of it completely (because that is incredibly hard, and might be overly complex), the goal is to get rid of things as much as possible and some products primarily, because burning petroleum is probably the most stupid way of usage.
At least the kids growing up on the internet right now will have some kind of perspective and understanding how the shit works.
I don't think this is necessarily the case. If stuff is too abstracted away for people to grasp, they can use it, but don't really understand it. Like reports of people saying that college kids cannot interact with things like folders. Some of them are so digitally native, that they really lost the understanding of it.
Some of them feel better than others. Very boiling is kinda weird.
Very powerful works imo.
