Q: Which of these deltas is most populated?

Below are GIS ( Global Information Systems ) maps of the human populations found in the five deltas. Unfortunately, animal and plant populations are a little harder to track as these populations don't respond too well to censuses!
Joel, who created these maps for us, wanted to note that in comparing these maps, be aware of the difference in scale. For example, the Mississippi river delta is relatively small compared to the Ganges and Amazon deltas. Since the Ganges is so big, the total poulation of this delta will be greater.
