Aerosolized Aluminum:

- Decimates forests and all plant life as it disrupts nutrient uptake and root system function

- Wipes out birds, insects, fish, and other sensitive wildlife

- Crosses blood-brain barrier in humans, causes birth defects, respiratory sickness, and significant mental dysfunction (including dementia), among countless other life-threatening health problems

NASA:
