Aral Sea Basin

"Dust blows from what was once the Aral Sea floor. Tragic mismanagement of a natural resource."

Joseph Thacker 's curator insight, February 20, 2014 9:49 PM

This is a sad reality humans must live with forever and something we as people must learn from. A man made disaster that occurred many years ago has a negative impact on areas surrounding the shrinking Aral Sea to this day. People cannot exploit an area of water this large, as this is not only harming the environment, but many human beings, as well

This startling picture from space of the Aral Sea is heartbreaking.  The destruction of this inland sea is a terrible thing to behold.

Jess Deady's curator insight, April 30, 2014 8:36 PM

The Aral Sea Basin has been a topic of conversation throughout geography for many reasons. What used to be filled with water is now blowing dust because its that dry? This basin is no longer a natural resource.

For Mexico City, a Repurposed Landfill

For Mexico City, a Repurposed Landfill | Geography in the classroom | Scoop.it
Methane from a landfill will flow to a power plant, helping to keep the lights on in the city.

 

When Mexico City’s government shut down the giant Bordo Poniente landfill last December, officials announced that they had a full-blown plan for the site...the city aims to capture the methane gas produced by the landfill to fuel a power plant that could supply electricity to as many as 35,000 homes.

(Central America topic 8)

This article bears striking resemblance to the situation unfolding just a few blocks from my home: Johnston's Central Landfill.

The main similarity is with the use of methane gas for electricity production. Not only is this  a 'green' form of energy (natural decomposition), but it helps to prevent the foul odor of methane gas from spreading to nearby cities and towns. Before upgrading methane pumps at the Central Landfill, my neighborhood smelled like a dumpster most days. Now the air is cleaner and clean electricity is being produced... "two birds, one stone." Hopefully other landfills will take these examples to meaning in some way.

Usually when a landfill becomes overloaded, it just gets shut down and left to rot. Mexico City is trying to do something new and ingenious with its massive landfill. Instead of closing off the land and letting it stay as reusable space, Mexico is hoping to develop a way to harness landfill gases in order to make electricity. If it is successful, it could prove to be a world-changing solution for other large, developing cities. It has the potential of lowering energy costs, creating jobs, and finding a purpose for land that would otherwise remain unusable for probably centuries.

In class we discussed the numerous environmental issues that exist in Mexico City. This is a great way of turning a negative into a positive. On a larger scale, I think this is going to be the kind of solutions that every country will have to eventually find. Creative ways of using technology to turn harmful waste into energy is a great idea. Methane is a cleaner than coal and recycling lessens the burden on natural resources.
