6 inches

A quote from a blog I just read. “The entire human enterprise depends on two things: Six inches of topsoil and the fact that it rains.” No matter how clever our inventions, no matter how beautiful our artwork, no matter how profound our works of literature or how powerful our weapons or how vast our (imaginary) wealth, we are in the end biological creatures who suffer and die quickly without air, food and water.
