Education reformers have long called for U.S. kids to log more time in the classroom so they can catch up with their peers elsewhere in the world, but resistance from leisure-loving teenagers isn't the only reason there is no mass movement to keep schoolchildren in their seats. Such a change could cost cash-strapped state governments and local school districts billions of dollars, strip teachers of a time-honored perk of their profession, and irk officials in states that already bridle at federal intrusion into their traditional control over education.

Texas already forbids school from starting before the fourth Monday of August, a provision designed to save money on utility bills and increase business for tourist destinations and other summer attractions. "Ultimately the states, not the federal government, should have the final word on this and other public school decisions," said Lucy Nashed, a spokeswoman for Gov. Rick Perry. In Kansas, sporadic efforts by local districts to extend the school year at even a few schools have been met by parental resistance, said state education commissioner Diane DeBacker.

With the global population bursting at the seams, the scarcity of rich land to grow food, and more demanding diets, food supplies are diminishing at an alarming rate.

The global population, which currently stands at 6.8 billion, is expected to reach 9 billion within the next 40 years. This is a lot of mouths to feed, especially in areas where population growth will be the highest; mainly Africa and India, which are already facing not only food shortages, but severe water shortages as well.
