Every time there is a spike in oil prices, or when food costs more, or there is a renewed worry about carbon and climate change, academics, pundits, and the press immediately point to the high consumption future of India and China.
They are wrong to do so when we consider the causes of energy and food challenges, and, more importantly, when we think of the actions and policies needed to manage changes in coming decades. If it is questionable that India and China are to blame for the global energy crunch, it is even less acceptable to expect them to adhere to pleas to moderate their energy consumption.
Historically, energy consumption has correlated with economic growth. The present debate over energy often focuses on two dimensions: climate change (from greenhouse gases), and the scarcity of fossil fuels.
India and China consume only 3 percent and 9 percent，respectively, of the world's petroleum today.

In California, the Pacific Plate and the North American Plate meet. The Pacific Plate covers most of the Pacific Ocean floor and the California coastline. The North American Plate stretches across the North American continent and parts of the Atlantic Ocean. The primary boundary between them is the San Andreas Fault. It is more than 650 miles long and extends 10 miles deep. Many smaller faults, such as the Hayward Fault, branch from the San Andreas Fault.
The Pacific Plate grinds northwestward past the North American Plate at a rate of about two inches per year. Parts of the San Andreas Fault system adapt to this movement by a constant "creep" resulting in frequent, moderate, earth tremors. In other areas, movement is not constant and strain can build up for hundreds of years resulting in strong earthquakes when it is released.
Unlike other natural disasters, there is no warning for earthquakes.
