Today in Science 10 we studied the fifth and final threat to biodiversity----Overharvesting! The students completed The Tragedy of the Goldfish activity. This activity had students go fishing using only a straw to catch the fish. Students only needed to catch two fish each round to feed their family, but most students found themselves catching as many as they could each round. It was so extreme that one group caught all of the fish out of their pond. Certainly a good example of what happens in the real world and why overharvesting is a threat to biodiversity. Here are some pictures of students fishing.
