What is the role of the antagonist in a story

The antagonist is the character in the story who opposes the protagonist which is the main character of a literary work. The antagonist does not change throughout the story which means the character is static. Most of the time, the antagonist is known as the "bad guy."

life will not be easy it will be filled with war, lack of resources, damaged planet, and lack of land to live on.
