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

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

Population Growth and the Rise of Mega-Cities: Can Technology Help?

Population Growth and the Rise of Mega-Cities: Can Technology Help? | HSC Geography | Scoop.it

Are you ready to share the planet with 7 billion people? Current projections estimate that this population milestone is only months away. Along with a rapidly growing world population, the wave of urban growth continues, causing cities to swell and new metropolitan centers to emerge. As of 2008, more than 50 percent of the world’s population lived in cities for the first time in history. In addition, a recent UN-Habitat report indicated that urbanization has become unstoppable and that by 2050, over 70 percent of the world will be in cities! It seems the world took Petula Clark’s song Downtown seriously.

World's largest cities are morphing into overcrowded 'mega regions' defined by poverty and pollution, UN report warns | HSC Geography | Scoop.it

Are mega regions sustainable? Is the Western city model the best one to implement even if it is “greened”? Are we going to continue pushing the envelope with a complete disregard for any constraints or consideration of the consequences? Will this help force a collapse as outlined in Limits To Growth: The 30-Year Update: http://www.amazon.com/Limits-Growth-Donella-H-Meadows/dp/193149858X ? Or is there a new paradigm just around the corner? We may be standing at the precipice. Let's figure out the best way to survive the projected nine billion population by the year 2050.

* Why Biodiversity Matters

How the rise of the megacity is changing the way we live

The rapid increase in the number of cities home to more than 10 million people will bring huge challenges … and opportunities... 

 

It's not just that more people now live in cities than in the rural countryside (for the first time in human history).  It's not just that major cities are growing increasingly more important to the global economy.  The rise of the megacities (cities over 10 million inhabitants) is a startling new phenomenon that really is something we've only seen in the last 50 years or so with the expectation that the number of megacities will double in the next 10 to 20 years (currently there are 23).  This reorganization of population entails wholesale restructuring of the economic, environmental, cultural and political networks.  The urban challenges that we face today are only going to become increasingly important in the future.

More and more people are moving to the cities than ever before.  As a result I believe there are more megacities on the way.  However I think there is a limit to these cities.  How are they going to be powered?  How are the people going to be fed? Where will they work?  how will these cities impact the environment?  Where is all the fresh water going to come from?

Seth Dixon's curator insight, September 30, 2013 4:40 AM

Kenny Dominguez's curator insight, December 11, 2013 9:26 PM

It is a good thing that there is more megacities being created because you can see more people move in which will help the city function better economics wise. When it comes down to the population that is a different story because there is more people to worry and deal with. The increase of people could go both ways because it can be good but at the same time it can go bad because people will start arguing in which it can get physical which means city ratings going down.
