I am not sure what you consider "not very worrying", as I don't think that the 5 million Indians and Pakistanis living in the UAE are responsible for much of the carbon footprint of the country. So for the Emiratis and Western expats, we should consider their per capita footprint to be at least double the average.
2) Israel uses desalination and their carbon footprint is 3 times lower.
Yes, Israel uses desalination and has a low carbon footprint, but they also have leadership that has historically been more concerned with water conservation.
No need to assume that any mention of Israel is a hot headed take on the Israel-Palestine situation.
While I acknowledge your sentiment, making these kinds of arguments is not acceptable. Please base your conclusions on facts or at least coherent, easy to follow logic. This will be better for you as well as your point will come across more easily.
Right now it just sounds like a lot of prejudice from someone who watched a lot of (quite sad) documentaries but actually has never been there in person nor is very well-versed in its politics and/or statistics.
It is a fact that there are a lot of low-paid migrant workers from India and Pakistan in Dubai, and it's a fact that many live in dormitories, and it's a fact that Dubai and the Emirates have a very dubious record on migrant worker rights, and indeed on human rights in general.
