Set aside the question wether the moon is moving closer to Earth, of further away, all this raises an eyebrow....
The Mariana's Trench? What does a trench in the northern pacific has to do with a country with no coastline ? I know in climatology, events can have an effect on the other side of the world, but come on, if you make claims like these you should at least back them up with some scientific reports.
I'd say you are trolling.
Socialists like giving aid to third world countries because a) it justifies higher taxation at home and b) they don't need to trouble themselves about the root causes.
Although your comment contains an elemtent of truth, I don't see anyone care about conflics and political instability in Africa (from which the 'average African suffers mostly). I believe it's better giving aid to those in need than to totally ignore the misery of millions. About the higher taxation: I do believe the annual spending of the average Western country (socialist or not) is only marginal compared to e.g. military expenses. And I (living in a social, not socialist country) have never heard anyone mention third-world aid as an excuse of higher taxation.
They may be able to produce 600V, but that doesn't say anything about the power they deliver. I reckon electric eels can only give a short burst of current (1 Amp), enough to defend themselves. So you get very unpredictable supply of power, and you would need many eels, since I don't believe an eel could provide current for more than a fraction of a second. High power, short burst, and thus little energy...
From your post I get the impression it has been done, but I think it wouldn't be easy and you'd need to apply quite some circuitery to get some usable output.
One solution could be to use spread spectrum modulation technique. I don't know exactly how safe this is, but emit a jamming signal, you would need a very powerful transmitter. This is due to the face that spread spectrum uses a very wide bandwidth, but at low amplitude signal. This is accomplished by multipliying the signal to be transmitted by a so-called pseudo-noise code, which comes at a much higher bitrate than the communicated signal. The result is, to jam the gps signal you would need to transmit powerful enough over a large bandwith (and thus require much power).
Another effect of the technique is that it's more or less encrypted (covert is a better word). By that I mean you need to know the exact 'pseudo-noise' (binary) code that is being used for communication between the gps sattelite (each connection has its own code). If the code is unknown to you, the gps communication appears to you as low power noise.
So as long as the pseudo-noise code is long enough, gps communications are relatively safe.
So far so good on theory, but i don't really know how secure you can get in practice, AND if gps sattelites are equipped with proper transmitters.
All this being said, this whole story seems like a very expensive solution to a non-problem (any terrorist with some brains will choose another, easier way to attack his target then to hijack a plane imho)

lol...
I'd mod you up for the Spinal Tap reference, but hey, it is alreadt +5, Funny
I just love moderator humour... Modding this up as insightful as actually at least as amusing as the original post :-)

Slashdot is so biased
"No shit..."
...since they were uncomfortable using the 'obscene' term "black hole" :-)
...like many people pointed out, it has been known for almost a week (since january 2nd to be precise).
