Describe one possible economic impact of redox reactions. how might that impact be lessened?

One of the possible impacts of redox reactions can cause rust on economic objects. Due to this economic impact we could lessen these chemical reactions by controlling them. As the redox reactions also have an imporatn impact on the soil, then the agriculture, which is a basis for economics, can be affected then that is another reason for the redox to be lessend by replacing them with another type of chemical. 

I'm not sure but i will try to find out
