I'm not buying it just yet, sorry mate.
let me explain why:
The Image
As far as the composition goes it would be great if you were taking a photo of the lake with a mountainous background. However, the focal point of the image is supposed to be the pylons and they are getting lost. It really doesn't suggest to me that this is a beautiful landscape being forged into a industrial denizen of human existence. It looks like what it is, a pretty landscape with some pylons in the middle distance.
As for the technical side of things, I think you could do with some more contrast and clone out the sensor dust around the clouds in the middle of the sky.
The Text
The opening sentence suggests that slowly over time humanity is taking over nature, but this image really doesn't suggest any theme of time at all. There is nothing to show the advancement of the ages or their effect on the landscape. If it were a series of the same location being built up over say a decade or two then this might work, but it's not being suggested by a single image, especially when there is really very little human intervention going on. Again the point you are trying to make is being lost by the fact that the pylons really aren't a focal point.
In the second paragraph you need more than one image to constitute a 'body of work', so I would be interested in seeing some other examples. I would also argue that the photo doesn't support your final supposition which is that there are chilling consequences to human expansion. The pylons might be an eye-sore but that's all they are. There is no detrimental effect on the native wildlife nor is there any evidence of say global warming affecting the snow on top of the mountain. There's no dead fish in the lake and there is no evidence of the leaves falling from the trees.
The Language
(sorry about this but I feel that correct grammar and a few alterations would make your theme and aims a bit clearer).
I've made some changes within the quote below to show how I would re-write your introduction to the theme:

I don't want to sound too critical but I tend to analyse every angle of a brief and it's solutions. I'm also a bit of a nit picker when it comes to language.
I hope my suggestions are useful.
*quick edit* seems Messiah and myself are on the same wavelength.
Baxi I think you need to make what you said in your reply to Messiah a bit clearer in the OP
