The concept of wildlife conservation has been around since ancient times. Restrictions on taking game are mentioned in the Bible, and the first official hunting season may have been established in the 13th century by Kublai Khan.
Today, wildlife conservation has evolved into a science, but its goal remains essentially the same: to ensure the wise use and management of renewable resources. Given the right circumstances, the living organisms that we call renewable resources can replenish themselves indefinitely.
Preservation is another means of protecting or saving a resource, such as by outlawing hunting of endangered species. Both preservation and conservation are necessary to sustain resources for future generations.
