Chemical contamination is when chemicals from industries or harmful sprays in farming get washed off into bodies of water.
I believe this would send two kinds of messages:
- lack of security: any time new war could be called and people killed, which means that long-term planning was difficult
-weakening of authority: any time other leader could take over and might want to "take revenge" on those supporting the current leader, which gives people incentive to be very careful in supporting their leaders
A village created by people from another area is called a "SETTLEMENT"
