The earth,sun,and water

It all started from school I found out that all the schools in district 3 were dumping everything they did not use into the ivory ocean. The ivory ocean leads out to the main drinking water source that's we everyone got sick. Stomach curdling screams filled the streets of district 3 people thought it was the flu mutating but they were wrong. Later that year people found out that the manufacturing company had the same idea. That year my dad died he drank the same water when he worked out in the fields for his plantation. Then the days got hotter and the night got colder it wasn't until long before the comets coming dangerously close to our atmosphere the elders told us it was fine until the comets reached earth.
