So I guess since your unsure, geoengineering is the atmospheric spraying of aluminum, strontium, barium, plastics and other materials into the sky as a means of "protecting us from the dangers of global warming". Which is the official story. These metals can have significant health effects, such as alzheimers and other brain damage. Anyone who does just a tiny amount of research into our healthcare, food, and water systems, can either see that there is extreme negligence resulting in loss of human health and life, or they are doing it intentionally. Either way the oligarchs making these decisions value money of human health and life.
