Today in marine biology we had 4 separate article discussions. The first was on positive and negative impacts on ecotourism. We talked about how ecotourism is a positive because it brings awareness to marine conservation but how it was negative in its effects on the local regions of marine life. The second article we talked about was how bringing alien species into a marine ecosystem brings upon negative effects. We talked about how by a new species be transported or brought into a new ecosystem how it messes up the whole food web and cause fatal consequences. The third article we talked about had to do with the effect of chronic oil spills on marine life. We learned that every year approximately 315,000 thick billed birds died because of these oil spills. Finally, the fourth article we talked about had to do with the impact of artificial reefs. We learned how artificial reefs actually attract more fish then real coral reefs. Thus providing a good replacement for dead coral.
