And yet, few if any government agencies are taking soil, tree ring, or water samples to find out what is negatively impacting our trees and plants and if aluminum is one of the causes of their decline.
    Charles Little notes in his book: “As it happens, aluminum is a common constituent of forest soils almost everywhere, but it is ‘locked up’ in aluminum silicates, and in this compound form is not available to tree and other plants, and therefore is no danger to them. But after the acid rains came…the silicates were broken down, and the aluminum was freed to be taken up by trees and plants. The metal kills the roots first. This means that trees can no longer absorb and transport needed nutrients, such as phosphate, calcium, and magnesium-essential fertilizers that are themselves leached away from the soil should by acid deposition…. The trees are weakened and can be invaded by insects or pathogens or succumb to extremes of weather-or all of the above, in which case they die…” https://www.agriculturedefensecoalition.org/?q=node/5940
