What are the effects of industrialization?

What are the harmful effects of cloud seeding in the industrialization on the atmosphere and the measure being used to combat?

• Answer:

  Cloud seeding uses Silver Iodide to provide nuclei for water to form droplets on. Like most chemicals, Silver Iodide can be harmful if ingested in large quantities, but this requires massive and/or continued exposure. Studies in 1977 and 1981 showed minimal residual traces after cloud seeding. Approximately 50 tons are used each year for this purpose, which is a very small amount in comparison to the total volume of the atmosphere. The effectiveness of cloud seeding is debatable - several organizations have given up on trying to use it in a systematic manner - eg the US National Oceanic and Atmospheric Administration (NOAA) gave up trying to mitigate hurricanes with cloud seeding in 1968 Rumors linking cloud seeding to the chemtrail hoax exist, however barium is not used for cloud seeding.
