Not to disagree about the beauty in Portugal, but I visited Singapore as a young child, and it's so much nicer now because of the greenery they're adding within the city.
Also, at Singapore population density (I have different numbers from the other commenter), even if the entire EU moved there it would still be 42% untouched (and the rest of the EU would be empty).
