10 Geographic ideas that changed the world

Via Seth Dixon

An interesting looking book which identifies ten ideas that 'changed the world'. If you are interested, the ten ideas are summarised here...

They are:

1. The map

2. The weather map

3. GIS 

4. Human adjustment of physical systems e.g. flood management

5. Water balance 

6. Human transformation of the earth

7. Interdependence

8. Central Place Theory

9. Megalopolis

10. A sense of place

Do you agree with these ?

What else has geography given the world ?
