The world didn't faced this much price rise forever from 1845. From 2005 even though the price of food grains increased 75% basic grains like rice raised up to 150%. During 2008, this rise pushed into starvation. The starvation level increased from 84.8 crore t0 92.3 crore during the year 2007 to 2008 and also 100 crore people were undernourished.
What is the reason for food shortage and price rise? This is not because of the difference between necessity and distribution. The irony between hike of petrol rate from 40 dollar to 150 dollar and price fall from 150dollars to 40 dollars. Doesn't caused by the variation in the necessity and distribution.
