Plants need CO2 AND “food” (fertilizer, manure, organics-rich mineralized soil, etc.) for their metabolism. Just like they need water. None of these inputs can take the place of the other, all are needed. Air - food - water.

Water? You mean like from the toilet?

Toilet water is ideal for plants minus the possible pathogenic bacteria and viri. human excretions contain high levels of uric acid which when exposed to air and co2 turns into urea the very same urea this article is about. In addition human solid wastes are very rich in phosphorus and potassium both needed for vigorous plant growth. In the not so far past human wastes were used for food crops in north America and are still used in Asia due to the aforementioned facts. I know of a couple of growers of cannabis that have composting toilets for the property and workers and that is used exclusively to grow high end organic cannabis it thrives on human excretions

For plants, that’d be ok. Also certain dogs cannot resist toilet water, I believe... ;-)
