 One fundamental thing is, the soil nutrients are so low. I was talking to the WFP director who is from United States. He said, this year our budget has to go up at least by four to six billion dollars, otherwise we cannot fulfill this because the number of famines we're expecting in many parts of Africa is so high. And he said, by 1935, I mean 2035, there could be severe famines in Chicago and Illinois region because the soil conditions have depleted so badly, it can easily happen. They're saying, in 1930s, what one orange would give you, today you need to eat eight oranges. Have… has anybody eaten eight oranges in a day, anytime? Eating eight oranges a day is not a possibility for most human beings. One orange, what it would give you, today it takes eight.
