I need to know the five most productive agricultural/industrial/energy producing regions of the US.
The agricultural regions can be found in this site.
(Broken Link Removed)
The major industrial regions include the Great Lakes and the Northeast.
Are there any other sites like the one posted for Industrial and energy producing regions?
how did the first americans live during the ice age?
I didn't find any -- but I didn't spend a lot of time looking. You might try Googling U.S. industrial region and U.S. energy-producing region.
