Why is the US worried about a bean grown in India

Usually, the US should be worried about making their economy bounce back, as double dip recession still haunts them and unemployment rate is at an all time high. But then I read about something which is amazingly surprising.

The US is actually worried about the escalating cost of Guar Bean grown in India's State of Rajasthan and the reason why they are worried is because this little crop has the ability to escalate the cost of oil extraction in US.

Oil Fields in Texas use a gum like substance made from Guar bean to use a technique called as Fracking, which enables them to pump oil more than 10000 feet below the ground. With a failed monsoon in India and the fear of an impending crop shortage, the price of this bean has escalated from USD 2 per KG to USD 30 per kg in recent months, and this is making the Americans shit in their pants.

Guess you can't shun us Americans, Can you?
