Mr. Frainer wanted to look at new found high rates of extinction, particularly in insects. He wanted to look at an ecosystem and see the affect extinction would have on it. He noticed that in order to maintain clean water and the inhabitants, insects were vital; if the bottom rung goes they all go. Frainer concluded that this rapid extinction is mainly from farm runoff and other toxins leaking into the water. This just goes to show how important it is to contain chemicals and not underestimate the importance of insects.
