Why are there hunting seasons?

Hunters have gone afield since the late 19th century in search of wildlife. For many years, hunting was not regulated and many species were nearly forced into extinction. As a result, hunting seasons were created and built around wildlife management and protecting a natural resource.
History
Throughout history, hunting seasons have provided an opportunity at herd management. Specific areas have a carrying capacity, or the maximum number of animals that the area can handle, and hunting seasons help to manage the number of animals in that area.
Significance
Each state is responsible for choosing the number of tags and permits for each hunting season. This helps control the number of animals harvested every year.
Benefits
Most hunting seasons occur in the fall and early winter months. Thinning the herds before winter prevents unnecessary winter kill due to harsh weather and decreased food levels.
Effects
Without hunting seasons, game populations would skyrocket. As more and more animals fight for food sources, disease and starvation would force natural selection to thin the herds.
Potential
Fall hunting seasons allow females to complete gestation periods and successfully birth healthy offspring. This keeps the herd healthy and ensures hunting seasons for future generations.
