What function does the motif of the cannon serve throughout the story?

The cannon continually pushes Farquhar to continue his journey through his dream and back to reality.

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

i imagine life will be easier in the sense that we will have better technology and better health and medical advances as well as infustructure growth and economic resilliance we will have much stronger militaries and probably be constintly fighting with other countries for resources and lang that is actually cleanenough to live or farm on . as well i think the need for fresh water will only brainliest answer lol

always metal! releases anger and stress! bands i suggest are trivium, lamb of god, slayer, and amon amarth
