Humans are made of the Earth

90% of the total number of cells in a human body are bacterial.

25%-50% of the human genome is viral DNA.

One of the single most important atoms in the human body is Iron. Iron is the single most common element of which the planet Earth is composed. Iron is integral to the most basic biological process that humans require, we need to breath oxygen. Iron carries Oxygen to every cell in our body. Iron catalyzes the reaction of Oxygen and Hydrogen to produce water, without this reaction our bodies become acidic, and we die within moments.

Humans are made of the biosphere we exist in. Humans are made of the Earth.

God fashioned humanity from the clay of the Earth.

What happens to us if we destroy the Earth, destroy the biosphere we are made from?

Canis lupus

Fierce, lean, loyal, social predators, cyclists run in packs. 

When I encounter another cyclist, I know without doubt that they are family.
