MARINE DEBRIS: Why would you move through the oceans if the oceans can move through you? - YouTube

Boyan Slat, founder and president The Ocean Cleanup: "I have invented a method to clean up almost half of the great Pacific's garbage patch in just 10 years, using the currents to my advantage." 

 

But the oceans won't get clean by means of just a great idea. The Ocean Cleanup aims to not only study the solution, but actually develop the world's first feasible approach to gyre remediation, by using the ocean's currents to its advantage. So there is much more work to be done.

Daniel LaLiberte's insight:

After watching this video, and another video with Boyan reporting on the feasibility study: (http://www.theoceancleanup.com/blog/show/item/the-ocean-cleanup-release-event.html) I get the sense that we haven't really been trying hard enough yet to clean up our mess.  And that, ironically enough, gives me hope that there is so much more we can do.

Although Boyan only claims his "gadget" can clean up about half of the plastic in 10 years, the smaller bits, which are probably much more numerous, will also be important to clean up, and it will likely be much more difficult. Some complain that the whole idea seems naive (http://sco.lt/6HvjRB) but it looks like there is a reasonable value proposition here.

Daniel - if to think without limits or confines is to be naive, then perhaps the world needs a little bit more of youth innovation? Thanks so much for your thoughtful contributions and re-scoops!

It turns out that the amount of plastic in the oceans is quite a lot less than previously thought. Or we don't know where it is in any case, which is perhaps more disturbing: "Ninety-nine percent of the ocean's plastic is missing" http://sco.lt/6AJ3Uv

Phytoremediation: Healing Urban Landscapes through Plants

Phytoremediation: Healing Urban Landscapes through Plants | Zero Footprint | Scoop.it
Two graduate students present a concept for a former harbor site in north Amsterdam exploring the benefits of phytoremediation.


In the world of modern architecture everything has to be sustainable. If this means that we have to take care of nature and use our resources wisely then maybe phytoremediation can be considered a sustainable method of re-designing highly polluted areas.


Healing, remediating, cleaning, and purifying contaminated soil using plants to extract pollutants is the method of phytoremediation. It is getting attention lately, as it appears to be an effective low-cost and sustainable alternative when dealing with polluted soils. Interlaced into a good landscape design strategy it can save money, improve quality of urban spaces, and provides active and aesthetic uses of polluted areas until they are safe for other uses. 


Three categories of pollution were distinguished: heavily polluted soils, which will take up to 200 years to clean, medium polluted soils (about 60 years to clean), and clean soils. According to the level of pollution, the distribution of public spaces, land use, and accessibility of the areas are defined. Heavily polluted areas are completely closed to access during the purification process, but still visible, providing aesthetical sight of the landscape.

Maybe before 200 years we will figure out how to speed up the process.
