Threats to Ecosystem: Cause and Solution There are various threats to the marine ecosystem. Three of the most common are: (a) Pollution from point and nonpoint sources; (b) Overexploitation of marine stocks that can deplete marine animals; and (c) Global climactic and oceanographic events that contribute to sea level rise, coastal erosion, storm, and intensified sea temperature Pollution Pollution, as threat to the marine system, stems from point and non-point sources. A major

Climate Change on Marine Mammals Sustained scientific observations reveal and alert everyone that climate change has asserted alarming effects on the oceans (Simmonds & Isaac 2007). Scientists agree that these effects are likely to be in the form of alterations in prey distribution and volume. They also agree that the more mobile species of marine mammals may possess enough resilience to adapt to the changes. But the extent of their

Positive Effects of Green Energy Green energy (such as wind, water, and solar power, as well as other sustainable options) has become a hot topic and a "buzz word" recently. Even though it may seem that everyone is talking about green energy, few people are actually doing anything about it. While it has been seen in the news, it has not been seen in the fields and oceans where it can

Website Three: http://www.sciencedaily.com. Authority: Respected science-based online magazine Accuracy: (a) since the ocean's food chain is based on "the growth of billions upon billions of microscopic plants" (including phytoplankton), and since new satellite data shows that ocean warming is "reducing these plants" this imperils marine life and ocean fisheries Currency: Data for this Science article take from the journal Nature. Purpose: Global warming is due to rising levels of carbon dioxide (burning of fossil

Coral Reefs Conclusion and Assessment to Experiment The experiment as described provides strong support for the idea that temperature directly affects coralline health and that even relatively small rises in temperature can have devastating effects on corals (and coral reefs) because such a shift in temperature has the effect of destroying the relationship between the corals and small symbionts that live in the corals. Rising temperatures drive the symbionts out of the

Rising Sea Levels: Boston Harbor Case The change in the climate of our planet is mainly a result of the increase in the global temperatures and the greenhouse gases. These gases and the rise in temperatures have affected our planet in many different ways. One of the most serious issues caused by these increased greenhouse gases and rise in temperatures is the increase in the water levels of sea. It has
