Seems like a fairly inefficient system tbqh – is it because we’re eating the wrong stuff? or is it because living organisms create a fixed amount of waste no matter what? Poop is weird. I’d like to understand it better.

One important thing to remember is that the things we eat come in different proportions to a human. For example, think of a cow. It is composed of the same types of chemicals as us – carbohydrates, amino acids, fats etc., but in different proportions. If we ate only cow, we would have to consume so much of it to obtain our requirement of the rarest amino acid, which would mean consuming too much of the others types. These would then have to be excreted.
Multiply this logic by all the other foods we eat, and you can see we will always end up with some extra compounds that need to be excreted.
