Manta Rays: How illegal Trade Eats Its Own Lunch - Ocean Poaching

Manta Rays: How illegal Trade Eats Its Own Lunch - Ocean Poaching | DSODE HSC Geography | Scoop.it

March 5, 2013 Damian Carrington: The Guardian Environment

 

The gills of this magnificent glider of the oceans are valuable, but the rays are worth far more alive than dead.

If you think that protecting wildlife, especially the big, sexy creatures, is a worthy thing to do but has little to with the lives of people, consider the case of the manta ray. A trade in their gills worth just $5-10m a year is devastating their populations which, in the places where it is developed, supports a tourist trade worth well over $100m a year... http://www.guardian.co.uk/environment/damian-carrington-blog/2013/mar/05/manta-rays-cites-illegal-wildlife-trade

100 African Cities Destroyed By Europeans

100 African Cities Destroyed By Europeans | DSODE HSC Geography | Scoop.it

"When tourists visit sub-Saharan Africa, they often wonder 'Why there are no historical buildings or monuments?'  The reason is simple. Europeans destroyed most of them. We only have a few drawings and descriptions by travelers who visited the places before their destruction. In some places, ruins are still visible. Many cities were abandoned when Europeans brought exotic diseases (smallpox and influenza) which started spreading and killing people. Most of those cities lie hidden. In fact the biggest part of Africa history is still under the ground."

Seth Dixon's curator insight, June 17, 11:29 AM

This article is a good introduction to historical African urbanism.  It is also a powerful reminder that the landscape does not only teach us based on what we see--the landscape can be a powerful witness by reminding us of the what is glaringly absent.

wereldvak's curator insight, July 3, 9:24 AM

Wat er nu door IS en andere extremisten (helaas) wordt gedaan is min of meer ook door Europa gedaan ten tijde van het kolonisatieproces. Vernietiging, maar ook uitroeien van de volken door ziekten heeft voor dit verdwijnen gezorgd. Er ligt nog wel heel veel onder de grond, overwoekerd door de natuur.

Living in the Age of Airplanes

Living in the Age of Airplanes | DSODE HSC Geography | Scoop.it

LIVING IN THE AGE OF AIRPLANES is a story about how the airplane has changed the world. Filmed in 18 countries across all 7 continents, it
renews our appreciation for one of the most extraordinary and awe-inspiring aspects of the modern world. The documentary is produced and directed by Brian J. Terwilliger (“One Six Right”), narrated by Harrison Ford, and features an original score by Academy Award-winning composer James Horner
("Avatar," "Titanic").

Sally Egan's insight:

This trailer for the film provides a wonderful overfiew of what aviation has done to chnage the world in which we live. Great stimulus for discussion relating to tourism as well as other aspects of globalisation. Encourage you to watch this trailer and then to see the entire film.

Mijnbouw en aardverschuivingen, een goede combinatie ...... 

PIRatE Lab's curator insight, April 7, 2014 11:48 AM

There are several reasons for mudslides--some are purely a result of physical geography and others are related to land use patterns.  This last week's mudslide in Washington state was a combination of the two and although this impacts one place (see on map), it is a good teaching moment to discuss the environmental impacts of land use patterns and resource extraction projects.  As seen in this interactive, the river was cutting at the base of the hill, while loggers were clear-cutting at the top of the mountain.  Trees help prevent erosion as the roots hold the soil in place--a critical piece to the puzzle in a very rainy climate.  With $1 million worth of timber on the slope, logging companies persisted despite objections from the Department of Natural Resources and some restrictions (but in hindsight, those restrictions clearly were not enough). 

 

View the impact in ArcGIS online: Before and After Swipe, LiDAR I and II, and Imagery.

 

Questions to Consider: Other than economic worth, what other ways are there to value and evaluate the environment?  How could this landscape have been protected and managed better or was this mudslide inevitable?

"It took the folks at Google to upgrade these choppy visual sequences from crude flip-book quality to true video footage. With the help of massive amounts of computer muscle, they have scrubbed away cloud cover, filled in missing pixels, digitally stitched puzzle-piece pictures together, until the growing, thriving, sometimes dying planet is revealed in all its dynamic churn. The images are striking not just because of their vast sweep of geography and time but also because of their staggering detail."
