The number of chickens will blow your mind. There was a world clock I saw once counting like population and a bunch of random statistics including chickens in approximated real time.
People under estimate how much fish is sold and eaten. There are also other kinds of fish available in Bangalore they come like $1.5/kg. They are basically the 'Chinese Pomfret', they are mostly found in lakes formed around water bodies downstream to dam spillways. These are almost algae to protein conversion organism. Their only cost is cost of transportation. You need to see just how much people eat this. The fact they are also by many a definition way more cheaper than even vegetables.
