Question: Counting all trees as well, does the number of living beings on Earth always remain constant?
Answer: In a way yes, since there is only a single living being in the Universe, which we are all individuals cells of.
Humanity is a single organ in the fully integrated, interdependent “body” of the Natural Universe.
How many inanimate, vegetative, animate and Human parts are in this integral system is irrelevant, as we all need to aspire to come to share its higher, systemic consciousness and perception instead of our limited and distorted “single-cell” view are stuck in today.
When we achieve that higher consciousness we slowly stop sending ourselves and individuals, and the fate of our physical bodies becomes irrelevant we are all fully integrated into Nature’s perfect, eternal, unlimited “circle of life”!
