Less than 250,000 people currently depend on food foraging as their main source of income. The remaining foragers so frequently inhabit habitats (cold locations, woodlands, islands) where other methods of food production are not viable.
To forage is to look for wild food sources. It has an impact on an animal's fitness because it's crucial to its capacity for survival and reproduction. A subfield of behavioral ecology known as foraging theory examines how animals respond to their living environments by changing how they forage. There are two basic categories of foraging. The first is solitary foraging, which occurs when animals go hunting alone. The second is foraging in groups.
Today, fewer than 250,000 people rely on food foraging as their main source of income. Because other methods of food production are not sustainable in these environments (cold places, forests, islands), the remaining food foragers frequently live there.
