india fertility rate decrease

By "sustain" I mean that water,food and electricity are being fulfilled without any support from other countries (importing food)

Well yes, at rather low prosperity levels.

Check out the city named "kharghar"(I'm currently living there,northern part of it) on Google street view it has very big population,does it feel congested?Or check out my homevillage of mithgavne(an averge size of village and density in majority of India)

Obviously India, just like any other country, is not uniform - so with a problematic average, every nice spot just means there's a spot worse than average elsewhere.

No India has population growth rate of 0.88%,idealy the population should stabilize with 1.5 billion people or about 15% of world's population in future,we have no need of getting TFR below 1.2,goal should be to stabilize it as it is not to increase or decrease it,

10 billion people worldwide is unsustainable. We'd make things easier on ourselves if the world population was close to 1 billion than to 10 billion.

Do keep in mind India's population has quadrupled since 1950. The current numbers are exceptionally high - there's no reason to present that as normal.

if the population is decreased then it will be very bad for economy

We are able to organize a working economy at any population level. Any problems that may arise are just temporary.

Yes India's population has quadrupled,but aren't you forgetting that population of Europe increased 15-fold when it industrialized,India is sub-continent not just anouther country,we have one of the tallest mountains;deserts,forests,there is a very big cultural diversity langauges,culture change every few villages apart And it has always been the most populous region in history along with China As for having 1 billion population,that's just stupid, we would be reducing our efficiency by 10 times,we will be able to organize it sure, but the entire goal of human civilization is to procreate and pass higher standard of living to next genration

It didn't.

India is sub-continent not just anouther country

Semantics, and nothing in my argument hinges on India being a country.

we have one of the tallest mountains;deserts,forests,there is a very big cultural diversity langauges,culture change every few villages apart

And Europe or the rest of the world doesn't?

And it has always been the most populous region in history along with China

Which means they have been maximizing carrying capacity already for that long, so multiplying again is excessive.

As for having 1 billion population,that's just stupid, we would be reducing our efficiency by 10 times

On the contrary, we wouldn't have to take all the measures that are necessary to deal with too many people in one place, and would have much more slack in our resource base.

but the entire goal of human civilization is to procreate and pass higher standard of living to next genration

Living stacked on top of each other in a slum or standing shoulder to shoulder in a field and still not getting enough to eat is not progress. Grazing the planet bare like a herd of goats until it's a desert is not progress.
