Gjerde says, "we used to think the solution to pollution was dilution." what do you think she means by this and what example does she provide?

Explanation:

I can give you the meaning. Likely in your notes somewhere is her example. I found out that she is a real person.

If you were using the first insecticides, they were made so that they were water soluble. When you were finished spraying, you put water into a large container before dumping it onto the ground. That way the concentration was reduced. The problem was, the insects mutated and the insecticide became ineffective, so you had to make stronger ones until today (herbicides that is plant killers) there really is no good way to keep these things out of the water table. The manufacturers assure us that we will not be harmed by Roundup. The courts in California are not so sure. If you want more, you should search out the history of roundup.

The example I think is the best example is disposable diapers. They are the most environmentally unfriendly thing I can think of.
