Relation To Humans
Local economies near major coral reefs benefit from an abundance of fish and other marine creatures as a food source. Reefs also provide recreational scuba diving and snorkeling tourism. These activities can damage coral.
In medicine, chemical compounds from corals are used for cancer, AIDS, pain, and other uses. Coral skeletons, e.g., Isididae are also used for bone grafting in humans.
Live coral is highly sought after for aquaria. Soft corals are easier to maintain in captivity than hard corals.

“We must get back into relation, vivid and nourishing relation to the cosmos and the universe.

—D.H. (David Herbert)
“The instincts of the ant are very unimportant, considered as the ant’s; but the moment a ray of relation is seen to extend from it to man, and the little drudge is seen to be a monitor, a little body with a mighty heart, then all its habits, even that said to be recently observed, that it never sleeps, become sublime.”
—Ralph Waldo Emerson (1803–1882)
“The land is the host and humans merely guests.”
