Wikipedia:WikiProject Ecoregions/Ecoregions : another way to see the World
The ecoregions, as defined in Wikipedia, are initially based in those defined by WWF, and may be found on the NWWF site. However, the main goal for WWF was to work on conservation.
We, I and many others, believe thinking ecoregion instead of political geography (ie, borders between "regions" being defined by soil/climate/life associations rather than by nation politics) is a better way to solve some global issues.
So, thinking ecoregion is not only meant to think "conservation", it is another way to analyse and to represent areas in the world. At a scale fitting with human understanding, and fitting with human actions.
