Problems facing world's oceans through the harvesting of its resources
How has human practices at harvesting ocean resources affected the ecological state of the ocean? What are sustainable ways we can harvest these much needed resources?
Work Log:
Narrowed the topic down from human intervention into a report about how the harvesting of ocean resources affect the natural order
Structure:
Introduction- Talk about the Background statistics, introduce what this report will be on, and present a few maps. Present the areas this report covers to answer the question
We must look at previous/current examples of human impact to work out solutions for the future
Deepwater Horizon oil spill- mostly done as of 23/10
Overfishing in Australia- still needs more info as of 23/10
Background Statistics:
According to a 2008 report the National Centre for Ecological Analysis and Synthesis, over 40% of the world's ocean at that time was being 'heavily' affected by human activity, and there are very few untouched places.
According to the newly created Ocean Health Index, a way to measure the status of the world's oceans by country, the oceans averaged 60 out of 100, which is far from good. The scores ranged from 36 (at Sierra Leone's coast) to 86 (in Jarvis island). In the analysis conducted in March, 2013, it was found that developed countries had much better scores, and only 5% of countries scored over 70, and 32% scored under 50%. http://www.nceas.ucsb.edu/news/how-healthy-are-our-oceans UPDATE- range is now 54 (east timor) to 94 (Heard and McDonald Islands)
The website states that the greatest cause of lowering scores is finding sustainable ways to harvest resources from the ocean ('food provisions' and 'natural products' are in the 30-40 range). The key to scoring better is to find sustainable ways to harvest resources
The map created by the ESRI, we can see:
The developed countries have a much higher score, while poorer countries (African nations and some Central American ones) tend to drop out. Countries with limited resources
