In the best-selling "The Hunger Games" book series, main character Katniss is able to survive in the wilderness by foraging the aquatic plant she was named after. She also manages to kill off a foe by feeding her a poisonous berry.
Most folks won't find themselves in a situation of life and death the way Katniss did, but foraging for food can be a fun pastime if you know which plants are edible and which ones pose a danger.
