And yet another assumption: "That would put Iowa as one of the worst or the worst in nitrogen pollution".
Since the percent from other states is not noted in this report of yours; how can you make that judgment? At best, you can only say that we might be tied with Illinois, since, allegedly, we share 28%. But the report does not say it is the worst; or that any other state is worse or better. You know what they say about assuming, mall-boy?
BS, you have never been good at math. You've yet to do the math to prove that reducing sales tax or income tax increases tax revenue. The above is another example of poor math skills.
If it is true that Iowa and Illinois alone produce 28%, it's not a big jump to conclude that no other state produces more.
When the drainage area covers 9 whole states, 18 partial states, (3 of which are included to 90% or greater) and parts of two Canadian Provinces, I think it's safe to say there are no states which exceed Iowa's production.
Besides all this gobbledy-gook you offer; there are many streams in Iowa that flow into other southern states, then on south to the gulf. Same with Illinois. Again; how would anyone know who's nitrogen was who's?
You're not good at geography either. No streams from Illinois flow into other southern states except via the Mississippi.
Again people measure he nitrogen and track where it comes from and goes.
Likewise, who needs the few being laid off in water quality at the state, when people like mallcontent use private research/nonprofit/authorities as their source for information on pollution? If you want to be a liberal and grow govt (like they always do); then stop using outside sources that have the same state information DNR should have! This alone negates your argument that we should not downsize the state DNR. If nonprofits are the experts you choose and rely on; then why do we need the experts at the DNR? Another double-standard exposed!
Having information and acting on it are two different things. The DNR has the ability to act, to correct the situation. Unless, of course, they lay off too many employees.
