My reasoning: Note that while many substances exist in nature, not very many exist in nature in pure, bulk form. Note also that "natural products chemistry" is a specialty within organic chemistry dealing with substances that are produced within living organisms. There are a lot of natural products out there that have not yet been discovered--but this is still a small subset of possible substances. | |
