How many elements of the periodic table could we safely get rid of?
Experts discuss which elements of the periodic table could be safely removed, with some suggesting that over half could be eliminated in a hunter-gatherer society. The essential elements for life and modern technology include carbon, hydrogen, oxygen, and nitrogen, as well as others like silicon, copper, and lithium.
Life depends on a core group of about a dozen elements, including carbon, hydrogen, oxygen, and nitrogen. Industrialized civilization relies on additional elements like silicon, copper, and lithium for technology and infrastructure. Some experts suggest that over half the periodic table could be eliminated in a hunter-gatherer society. Essential elements for life and technology cannot be removed without significant consequences. The natural abundance of elements generally decreases with increasing atomic number, and evolution has employed the most abundant elements in biochemical systems. Removing certain elements, like those above uranium, might have little effect.
