| If you're ever at risk of thinking that plants are like people,
| you can cure it by reading about alternation of generation in
| bryophytes. If bryophytes were like humans it would be like if
| our (haploid) sperm/eggs went out and got a job and an apartment
| and a social life and only bothered spin up a (diploid) human for
| sexy times. Plants are bizarre.

| Like grasspea ( "Lathyrus sativus",
| https://en.wikipedia.org/wiki/Lathyrus_sativus ), sort of a
| bean which strangely, can be eaten a few times to fend off
| starvation but "The crop is harmless to humans in small
| quantities, but eating it as a major part of the diet over a
| three-month period can cause permanent paralysis below the
| knees in adults and brain damage in children, a disorder known
| as lathyrism."
|
| Imagine having nothing to eat but grasspea, each day telling
| yourself: "Last time, tomorrow I'll have a nice loaf of bread
| with steak". Only to resort to grasspeas again, each day closer
| to the point of no return.
