There are different motifs for studying and learning bushcraft. Some do it purely for the thrill of abandoning the security of civilization and venturing into an unknown area with a burgeoning vulnerability as his sole companion. Others do it for practicality's sake – so they could be prepared for disasters and emergencies. There are also those who do it to gain a pseudo connection and a better understanding of their ancestors who lived with primal means. And, of course, there are also those who want to escape the four walls of the technology age and reconnect with nature.
Whichever the reason, all of them are bound by a common goal: to learn how to adapt to and survive in the wilds.
