I need help with an idea

I'm taking a class where I have to give a presentation about some sort of shady business practice. Here is the actual assignment info from the syllabus
We all have issues with some business practices. Some stores won’t take back merchandise, others only give you in-store credit. Some businesses make products in America which are illegal to use in America, then sell these products to foreign countries. (DDT insecticide). Some businesses add ingredients’ to their food, ingredients that are known to cause cancer, but it makes the food taste better. Some businesses move manufacturing operations out of America to low wage countries, but then want to sell these products back to America. Some companies move just across the boarder to Mexico simply to avoid having to implement American pollution standards, then winds blow the pollution back over to American air-space. Some companies are in the business of war, they manufacture weapons and lobby hard to urge politicians to maintain or expand wars. Some companies are in the natural resources industry and lobby politicians to dilute environmental laws in order to access more natural resources – natural resources know to cause global warming and eventually lead to significant problems for the world.

And sometimes people trash perfectly good business practices….practices that you see a lot of good in, and others dislike. For example, you may have grown up in Pendleton and know that the Hydro Electrical dams on the Columbia River create water reserves which allow farmers to grow thousands of acres of wheat, feeding thousands of people. Other’s see the Electrical companies dams on the Columbia as blocking salmon runs and destroying native fish runs. Which practice is right? Pick a side and argue for it, and try to develop a solution.

So if any of you have any ideas please let me know. I have two weeks until I have to present.
