It is interesting to read how farm income was down last year despite corn yields being up by more 30 percent ("State's farm incomes take a hit," April 1). The ag community (chemical suppliers and farmers) are continuing to drive for more yield at the expense of polluting all the waterways — streams, lakes, rivers and wetlands in our state and those downstream from us. The phosphates and nitrates in our water are at extraordinary and increasing levels. It is imperative that litigation be initiated for the ag community to pay for its pollution. A per-acre tax on every nonorganic acre of farmland to be paid by the ag producer and the chemical suppliers — perhaps that will help pay for the remediation of our water, our waterways and rural water wells.

Can someone tell me why the researchers at the University of Minnesota waste their time genetically modifying corn to increase yield when its only apparent net effect is to lower the price of corn, instead of doing something productive like modifying a row crop to grow vanilla beans or cocoa beans or coffee beans?

JAMAR CLARK CASE
Don't draw certain conclusions based on this DNA evidence
Both the Star Tribune's March 31 news coverage about Hennepin County Attorney Mike Freeman's decision in the Jamar Clark case ("Freeman cites wealth of evidence) and its editorial ("Justice done, peace needed in Clark case") drew conclusions that aren't warranted from the state Bureau of Criminal Apprehension's DNA analysis on the grip of Minneapolis police officer Mark Ringgenberg's gun.
The BCA's report states that Ringgenberg and Clark "cannot be excluded from being possible contributors." "Cannot be excluded" means the BCA can't say that Clark's DNA wasn't on the grip of Ringgenberg's gun. It also doesn't mean the BCA can say that it was. It means the BCA can't say for sure one way or the other.
However, both the news story and editorial state that Clark's DNA was found on the grip of Ringgenberg's gun. That's just plain wrong.
It turns out that Clark's DNA was found on Ringgenberg's holster and mace holder. This could have happened during the scuffle without Clark's trying to grab Ringgenberg's gun.
The DNA evidence does support the officers' version of events more than it does the witnesses' stories that have Clark being shot in cold blood while he was handcuffed. However, you need to be careful about reading things into a report that just aren't there.
