The LifeStraw filter meets EPA standards and has been shown to remove more than 99.9% of waterborne parasites and bacteria. Humanitarian relief workers in all corners of the globe use the LifeStraw to help bring safe water to threatened communities and refugee camps. The “straw” itself weighs a scant 0.1 pounds and measures 9” in length and 1” in diameter. Few things are worse than being lost and being besieged by waterborne illness. Bring this essential piece of survival gear with you whenever you venture into the wild and make sure water problems are not on the menu.
The reëlection of Barack Obama was a boon for the prepping industry. Conservative devotees, who accused Obama of stoking racial tensions, restricting gun rights, and expanding the national debt, loaded up on the types of freeze-dried cottage cheese and beef stroganoff promoted by commentators like Glenn Beck and Sean Hannity.

Experts worry most about the grid’s nervous system: 2,000 extra-high voltage transformers. They’re 200- and 300-ton behemoths, individually engineered to meet specific power demands, and on average, they’re 40 years old. Notwithstanding the fact that 85 percent of transformers are imported, the U.S. Department of Energy says it takes between 5 and 16 months to replace a single one. According to the U.S. Federal Energy Regulatory Committee, an attack that destroyed nine of the 2,000 transformers would “cause a protracted nationwide blackout.” There’s no national cache of spare transformers. 
When I got into bed that night, I noticed I was feeling a little off. Though I’d technically consumed enough calories, my stomach was still gnawing with hunger, and when I woke up the next morning, I felt energyless. I phoned Dr. Lisa Young, a New York–based nutritionist and adjunct professor at NYU, with a question: Is it really possible to live off freeze-dried food?
When bands of marauders start roaming the streets, how are you going to keep them out? Tear down a few walls, says Timothy Ferraro, a twenty-five-year construction veteran who's thought about this situation plenty while watching The Walking Dead. "Assuming the attackers don't have a battering ram, you should be able to keep them out using the lumber and drywall already in your home," he says.
