Long after the weight of ages has ground our works and bones to scattered dust, the changes we’ve made to the nitrogen cycle will stick out in the geologic record.
The jump from base levels of nitrogen to the obviously unnaturally higher amounts that would remain in layers from our time just wouldn’t have any explanation other than something did it on purpose. There’s basically no way for that level of increase to occur in what is geologically the blink of an eye without industrial capacity. Or that’s what I’ve heard.
Fertilizer is what I’ve heard.
