Other Activities of Bacteria
There are very definitely other important features in bacteria,
which make such a major contribution to life on Earth by making

photosynthesis, protect our bodies, give rise to the most important
life cycle on Earth, but which are so small as to be invisible to the
naked eye, addition to displaying the superior intellect and artistry
in their Creation. Bacteria also represent the source of the world's
iron reserves, and even of the iron in our bodies.

Some bacteria possess the ability to separate out the iron dis-
solved in sea water, consuming the iron molecules and concentrat-
ing them in their own bodies. The iron thus concentrated then
forms layers on the sea bed. Over the course of millions of years,
these layers are raised up into mountains and form enormous veins
of iron oxide. When these layers are dug up, a large quantity of iron

molecules become released into the air. Then, all unknowingly, we
breathe in this iron dust—absorbing molecules of the greatest im-
