Pacific nation Tuvalu has grown by 73 hectares over 40 years

Pacific nation Tuvalu has grown by 73 hectares over 40 years | Education in a Multicultural Society | Scoop.it

"The tiny Pacific nation of Tuvalu – once thought to be under threat from rising sea levels – has grown the size of California's Disneyland over the past 40 years. It's mostly thanks to waves dumping extra sediment, sand and gravel on shore lines, according to research by Auckland University scientists. The study, published in the Nature Communications journal on Friday, was the first in-depth look at how much each of Tuvalu's 101 islands have changed over the decades."

Is Zealandia the eighth continent?

"A group of geologists say they've enough evidence to confirm the existence of a new continent. Writing in the journal of the Geological Society of America, the group named the eighth continent 'Zealandia.' Scientists argue for an 8th continent, Zealandia, in the Geological Society of America."

With 94% of Zealandia lying under water, most average people around the world will not care if National Geographic prints maps with an eighth continent. As cynical as that may be, geography should not be settled by human emotions and cultural expectations. Geography is a discipline that aims for understanding and precision. If continents are to be decided by continental shelves, rather than human cultural and ethnic patterns, then Eurasia is a continent and so is Zealandia. This latter outlook of focusing on physical geography is far more neutral and scientific. I would argue that is also more 'progressive'. Humans originate from one place (Africa) and are all one species. We have far more similarities than differences. Orienting our worldview to see that cultural geography is not the final arbiter of truth would ultimately bring people together. The logic follows that by acknowledging Zealandia, there is precedent for greater accuracy based on science, allowing geographers to teach about Eurasia. This is significant because it would alter the perception that Asians and Europeans are extremely distinct and separate groups due to a distorted notion that they lived on separate continents. The truth is that both groups existed on the same continent and were often brought into contact with each other throughout history. This idea, however, would further shatter the notion of a "pure, homogeneous Europe." Europe is only a "continent" because white Europeans were the first to possess the right combination of "guns, germs, and steel" to conquer other societies and elevate their own group's cultural status. Despite nature's evidence, Europeans awarded themselves an entire continent. In reality, Europe is a large peninsula of Asia. Just as Zealandia is an eighth continent sleeping underneath the waves.

This is interesting to think about. What decides what separates continents, is it geological barriers, is it culture, is it ethnic origin, or maybe even plate tectonics? Either way you look at it New Zealand makes a great case for why they could become to be considered the eighth continent. I could argue either way, to keep it simple and go by culture and geological commonalities (Oceania Islands) I would prefer it does not form its own continent. These geologist would argue otherwise.

Why Is Greenland an Island but Australia a Continent?

Why Is Greenland an Island but Australia a Continent? | Education in a Multicultural Society | Scoop.it

"Why is Australia a continent and Greenland is not? Even though Australia is the smallest of the accepted continents, Australia is still more than 3.5 times larger than Greenland. There has to be a line in the sand between small continent and the world's largest island and traditionally that line exists between Australia and Greenland. Geologically, Australia lies on its own major tectonic plate while Greenland is part of the North American plate."

I'm sharing this link for two reasons. 

  1. To help resolve the confusion as to why Greenland the world's largest island but Australia gets to be the smallest continent. The main reason is all about the continental shelf and not the coastline--Greenland is connected to North America to the continental shelf while Australia has its own shelf. 
  2. I know many of you have been fans of Matt Rosenberg's online resources over the years.  If you have lost track of him, he is continuing to share geographic information on ThoughtCo

Australia is 3.5 times larger than Greenland and this article talks about how there is no internationally recognized definition of a continent. Though there is no internationally recognized definition the line between island and continent lies somewhere between Greenland and Australia. It is also worth noting that Australia sits on its own tectonic plate where Greenland is part of the North American plate.
