As title suggests, I might be clearing pre based on few answer keys. So need some guidance for mains from veterans:

1. I've primarily prepared for UPSC. Don't know Bengal specific things(shameful as a Bengali, ik). What books should I purchase for WB specific knowledge?
2. What coachings/ materials, online/offline do you recommend?
3. What PYQ compilation book do you recommend?
4. Is CGL level math&reasoning enough for Mains?
5. Any resources on Pol Sci. optional, or should I rely on UPSC prep?
6. As I've lived outside WB, I don't know to read/write Bangla, what/how is checked during interview and how can I prepare for it.
7. When can I expect Prelims result and when is Mains exam likely going to be held?

Any and all help appreciated!

Title

I'm from India, and here we build very functional buildings- non-asthetic, soulless and only what's needed. Whenever I see poeple complaining about the beauty of a city, I see them comparing it to famous megacities- New York, Tokyo, Shanghai, Hong Kong etc.

But here, I see people appreciating a different asthetic- buildings with creepers, plants growing over them. This got me thinking- what could be a large scale city, made entirely keeping sustainability in mind look like?
Don't get me wrong, the pics of Chengdu seem nice, but it's just some plants masking what is essentially a concrete jungle. I'm asking about a city built by enviromnent conscious people, from the ground up. What will be the building materials? What will be the transportation? What will roads/public infra look like? What will be the energy sources? How will food production be accomodated? Will it be a self sufficient city or a globalised and specialised one?
Feel free to share your ideas about the cities of the future.
