Biodiversity

I believe biological diversity should be defined in the same way for both scientific and practical purposes as these are, to me, the same thing, although there could be cases where certain information is more pertinent than others. I would define biological diversity as how many individual species live in a given area, while also considering how many individuals of each species live there. This would give a general idea of the biodiversity of an area, but would still leave out information like species evenness. In some cases omitting certain information would be suitable, and would help to simplify the point being made. This is good for both the person doing the study, and someone reading it.
