Hey there! I love to visit India often. Have you ever been there?
I've never been to India but I've always studied about it.  It is the seventh-largest country by land mass, but the second most populated country behind only China.
Yes, there is so many people there! A lot of pollution too in some areas.
Yeah, that's usually what happens when it's so populated and it's not that technologically advanced.  India is also surrounded by the Indian Ocean and the Arabian Sea.  Fishing is one of its main food sources.
Funny story... I was visiting an area on the coast of the Indian ocean. I got up to watch the sunrise, and ended up stepping in human feces... people defecate along the beach in the morning. Yummy right?
Yummy indeed - being the third largest of the world's oceanic divisions, it comes with its fair amount of pollution and human feces.  I hope you washed your feet after that.
haha, yes very excessively. Other than that, it's a beautiful place. They just don't have the same infrastructure and plumbing as other countries. 
India is so big that it shares the same borders as Thailand and Indonesia.  I always wondered how such a big city didn't become more technologically advanced.
