Answer 1

     Many invasive species have started to disrupt the ecosystem of the Great Lakes. They are also a threat to the economy due to the effect they have had on native life by taking up space and food. Although permits have started to be made, nothing has really had a great effect on decreasing the number of invasive species. This has been made especially more difficult, by the fact that some reproduce asexually. The species are carried by boats and even clothing from waders in the lakes, and are continuously being spread. No plan has successfully stopped the invaders from coming into our waters, and the subject is currently being researched.

Answer 2

Good summarization by teenEditor. I can't improve on that!

Answer 3

Here it is:

Today, a very lazy person decided not to do her homework about an invasive snail found in Lake Michigan.  Therefore, he went to Yahoo Answers instead of trying to figure out how to summarize the article himself, and promptly failed the class.
