The last paragraph

The last paragraph that was recently added does not seem to fit the tone for Wikipedia articles. Because it's well-written I'll leave it to someone else to decide whether to edit or delete it altogether but it is opinionated and contains no citations. It might be more appropriate if it was a quote from some authority on the subject. I'm referring to this paragraph:

World awareness of the negative environmental impacts of enormous projects such as the Itaipú dam make it difficult to imagine the possibility today of a government succeeding in carrying out such a project in the future. It should be remembered, however, that throughout the planning and construction of the Itaipú dam, Brazil was ruled by a military regime that after taking power in a coup in 1964, abolished democratic government and encouraged in all ways possible – in the censored press, in the media, and in the arts, e.g., an ode to the Itaipú damn composed by American composer Philip Glass – public praise of the feat as an historic milestone, a great engineering accomplishment, and (principally) as proof of Brazil's development. But those who admire Itaipú perhaps don't realize that in order to build the world's largest dam, Brazil destroyed the world's largest waterfall.

The paragraph in question (the content of which I happen to concur with, for the most part) is contrary to policy and precedent, and the article has other major issues. A copyedit and general cleanup has been on my to-do list for a couple of weeks. I hope to get to it soon, but don't be shy about editing it in the meantime.

(Following up) I've reworked most of the article, copyediting and expanding the lead section and rewriting most of the rest. The paragraph quoted by SteinwayPianoman is gone per WP:NOR (at the very least). The long poem is gone per multiple reasons, among them copyright concerns (I left an excerpt). I did have some questions, here and there, and tried to be conservative in my wording when I couldn't verify a fact one way or the other. A photo would be very nice.

Map request:

The map in the article should be indicating the position of Guaíra Falls in South Ameriaca, but there is no mark on it. I am not sure how to add a mark to SVG map. Could you, please, add a mark on 24°04′23″S 54°17′02″W ?

I rarely work with vector images and am really overextended this month anyway. You might ask at the Graphics Lab, where you'll find editors for whom your request should pose no challenge. Rivertorch (talk) 16:50, 14 November 2013 (UTC)[reply]

Dynamiting Falls

Does anybody have a news story or report in engineering literature for the demolition of the falls? I'm having trouble visualizing how that was done, or the reasons for it. Eliminating a sharp change in elevation in a river is an engineering project of at least the same order of magnitude as the dam itself, and it's not immediately obvious to me how it would improve navigation. It's tricky to conduct explosive demolition underwater like the current wording implies, and I'd like to find out more about how it was done and why. Also, AFAIK, dynamite isn't a good explosive for wet holes, so I'm guessing that something got garbled in translation.

Right now, there seems to be a circle of references with the International Rivers site, which only mentions it in passing. CatCube 140.194.140.21 (talk) 20:14, 31 May 2016 (UTC)[reply]

There seems to be a dearth of reliable sources out there pertaining to these falls, but I haven't given up (and keep meaning to get back to working on the article). If you find anything on the dynamiting, please add it or at least provide a link here. Rivertorch's Evil Twin (talk) 19:52, 1 June 2016 (UTC)[reply]
