Over 95% of our body is water. To stay healthy we have to drink good water. Our DNA is the same DNA as the tree. The tree breathes what we exhale. When the tree exhales we need what the tree exhales. We have a common destiny with the tree.
Man plants the seed - the alder tree grows - absorbing carbon from the atmosphere - storing nitrogen in its root sacs - exhaling oxygen - on which man's survival is predated - just by adding water - and so the cycle of LIFE continues.
