Surviving in the Amazon is a strenuous task. Since the Amazon is so humid it is impossible to make a fire in the forest so as an explorer you are surviving off of raw fish, nuts, or any perishable items you brought with you. Since the food options are very slim you have to learn to adapt and become great at things you probably never experienced. Paul said that he became a great fisherman due to the fact that fish was their main source of food. Outside of food, diseases are hard to avoid in the forest as well. it is impossible to stay dry in the forest so you become more susceptible to diseases such as staff infections, bug bites, etc.
