Should Synthetic Organisms be released to clean plastic pollution from the ocean?
The Problem: Microplastic pollution in the ocean.
Proposed Solution: Engineered Organisms that can collect the pollution into recyclable pieces. (the science behind this: http://www.ucl.ac.uk/igem2012 )
A video explanation: http://youtu.be/rEDLg03teOk
Should Synthetic Organisms be released to clean plastic pollution from the ocean? Is synthetic biology the only solution to plastic pollution? Can we anticipate and prevent any negative repercussions? Do the potential risks outweigh the benefits? Who could profit from this? Who calls the shots?

How did such large quantities of plastic become deposited in the seas in the first place? By our certain knowledge that no great harm would come of it!
I would rather trust nature to take care of the problem in its own manner in its own time, even if it takes 10,000 years - that is a mere blip. The most important role we can play is to stop adding to the problems nature must contend with. The clear lesson is not to be so disregarding of things we don't understand.

I like Debra Smith's solution; go out there and pick it up; we need the jobs. Then when we calculate the cost of cleaning up all that plastic we can add it to the price of future plastic products. Plastic sales will plummet.

Get out there and understand every molecule of the world's oceans before you loose a single microbe from your lab!
Ecosystems are inordinately complex and I bet you don't even know all the details of the microbes you're playing with. Let's be honest here, you've tweaked a gene here and a gene there in some 'coli's and Roseobacters, right?
Build an E. coli from scratch first, model every last amino acid, be able to count every phospholipid, ion, even the water molecules! Then be able to list every epigenetic change possible in Escherichia Coli that can be triggered environmentally, or by the little bugger's own whim, etc. Not necessary to memorize, but at least have the entirety of organic chemistry modeled in some ridiculously powerful supercomputer. Be able to map the location of every single entity over half a kilodalton in the all the oceans, whether it can wiggle or not. (Should keep ya busy a while eh?)
Then you can play god with the Pacific.

Energy is what keeps living things going or being alive regardless it's source. On this globe called earth we have energy captured from the sun either concurrent with it use or as fossil sources and from spiting or combining elements, fusion and fission. Wind, water, bio fuels and direct capture of the suns rays are all solar based, but are energy. Only one of them can be transformed in to something resembling plastic. Even the plastic you suggest as a substitute was made only through the application of energy. The value of any object is nothing more than the energy the purchaser is willing to offer. Money is a storage device for the ability to command energy. When we spend money we are offering energy or buying the energy it took to bring the item being purchased to where we purchase the item.

I am reminded on the solution the operators of one solid wast incinerator adopted to solve the problem they were having with plastic containers. The plastic containers fouled and clogged the feed mechanism.They pulled them out of the trash feed to the incinerator for several months and then fed them all at once to the grates. Well plastics are high energy elements and the grates were melted putting the incinerator out of service for several months. Be careful how you recover a waste where it may be.

Separately, we have an exonuclease system that will degenerate any extracellular DNA, preventing genes from being released into the environment after cell death.
What other kinds of safeguards do you think are necessary if such a system is actually put into place?

I think the best solution is to educate people about the use of plastic and promote recycling. And as Charles suggested, the best solution is to stop the production and use of plastic.
V Alexander
You sum it up perfectly, Oyeronke. The foreseeable is quite finite and obviously non-inclusive of the unforeseeable.

The author seems pretty biased in favor of Venter, but I still found it an interesting (and frightening) read. It doesn't really sound like there's any "if" about it... these guys are just going to do it and see what happens.

(It would be impossible to test the effect of nanobots on all of the species in the oceans; we haven't discovered all of them yet.)

Perhaps in a few decades we will have whole cities and buildings that will grow instead of being constructed. These buildings will be synthetic life forms, they might sustain from human waste and provide for most of our needs, combined with robotic and AI, synthetic biology will make the world much more natural and harmonious than without.

The main difference in synthetic biology is that it focuses on establishing tools to do so in a standardised way, allowing different labs to design gene constructs that are compatible with each other.
Within the scope of the iGEM competition we are a part of, this includes finding 'useful' genes, isolating them for transformation into microbial cells such as E.Coli, and submitting these new gene constructs to a centralised registry so that future teams can utilise the genetic constructs we have made.

And for the risk of this magnitude I would not choose this technology for the described problem.

The problem with this is: Small organisms don't live long so removing their reproductive capability may result in faliure to remove plastic. Keeping a reproductive capability may remove more plastic but as small organisms have short generation times there is increased probability of evolutionary adaptation to a new food source. Perfecting a balanced organism that exists somewhere in the midst of this dichotomy will be very difficult indeed.

Somehow your project reminds me of Wall-E :D

So, no, I believe that introducing synthetic organisms to clean-up our garbage in the oceans is a wrong approach. In the end, human muscle power and machinery is always the better solutioin.

Oh, that was not what you meant by synthetic life?
***********Addition;
In fact, I was wrong - the man I rerferred to above is from Germany. Here is alink which discusses his use of plastic bottles to create a home island and his philosphy.
