We are always hearing about how introduced species have hurt native species, through either predation or competition. On the other hand, what are some examples of introduced species becoming victims of native species? (Hint: there is one such example in the book!). What are some examples of introduced species overall helping the native community? What are some examples of introduced species overall hurting the native community? Looking at these examples, do you think that we should continue to take it upon ourselves to introduce species, or should we be working to make sure that it stops happening? Also, could introduced species eventually be strong evidence for evolution a couple of hundred of years from now, if we start recording if and how they change to their new environments now?
