A potentially lifesaving guide on how to find and prepare safe drinking water in extreme situations, ranging from backpacking treks to natural disasters Humans can only survive three days without water, and most of the world's water is not safe for drinking. What happens when a person's water supply is unsafe? This frightening question is a real concern for backpackers who venture into territories with unstable water access. And for the many people who enjoy learning outdoor survival skills - whether seriously or for fun - understanding methods to filter or distill water, with minimal use of equipment, is of plenty interest, too. Biologist, survival expert, and author Joe Vogel's scientifically backed, practical, and easy-to-understand handbook offers lifesaving advice on how to find, assess, treat, and store safe drinking water in the most extreme places, ranging from hurricane-ravaged cities to remote deserts. Small enough for hikers to take with them on treks but broad enough to cover all relevant options for finding and purifying water, Vogel's book is a vital manual for anyone hitting the trail, or otherwise unable to take clean water for granted.

Master outdoorsman Tristan Gooley was just about to make camp when he sensed danger--but couldn't say why. After sheltering elsewhere, Gooley returned to investigate: What had set off his subconscious alarm?

Suddenly, he understood: All of the tree trunks were slightly bent. The ground had already shifted once and could easily become treacherous in a storm.

The Nature Instinct shows how we, too, can unlock this intuitive understanding of our surroundings. Learn to sense the forest's edge from deep in the woods, or whether a wild animal might pose danger--before you even know how you know.
