What is a weed?

Well written, but nothing new from the extended prose on appreciating weeds.

Here's my latest definition:

A weed is first of all a plant of any species.

Secondly, it is a plant that at any given time and place happens to present problems or economic issues to farmers, land managers or gardeners involved in cultivating prefered plants or clearing vegatation from various spaces for purposes of human interest.

Thirdly, such purposes and behaviors offer little or no benefit to the natural ecology.

Forthly, agriculture is the most devasting event that ever threatened the diversity of species on this planet.

So far.

Anything that grows where you don't want it to.
