The stalk of the hemp plant has two parts, called the bast and the hurd. The fiber (bast) of the hemp plant can be woven into almost any kind of cloth. It is very durable. In fact, the first Levi's blue jeans were made out of hemp for just this reason. Compared to all the other natural fibers available, hemp is more suitable for a large number of applications.

Here is how hemp is harvested for fiber:

A field of closely spaced hemp is allowed to grow until the leaves fall off. The hemp is then cut down and it lies in the field for some time washed by the rain. It is turned over once to expose both sides of the stalk evenly. During this time, the hurd softens up and many minerals are returned to the soil. This is called "retting", and after this step is complete, the stalks are brought to a machine which separates the bast and the hurd. We are lucky to have machines today - men used to do this last part by hand with hours of back-breaking labor.

Hemp does not produce quite as much protein as soy, but hemp seed protein is of a higher quality than soy. Agricultural considerations may make hemp the food crop of the future. In addition to the fact that hemp is an easy crop to grow, it also resists UV-B light, which is a kind of sunlight blocked by the ozone layer. Soy beans do not take UV-B light very well. If the ozone layer were to deplete by 16%, which by some estimates is very possible, soy production would fall by 25-30%.

We may have to grow hemp or starve - and it won't be the first time that this has happened. Hemp has been used to "bail out" many populations in time of famine. Unfortunately, because of various political factors, starving people in today's underdeveloped countries are not taking advantage of this crop. In some places, this is because government officials would call it "marijuana" and pull up the crop. In other countries, it is because the farmers are busy growing coca and poppies to produce cocaine and heroin for the local Drug Lord. This is truly a sad state of affairs. Hopefully someday the Peace Corps will be able to teach modern hemp seed farming techniques and end the world's protein shortage.

Hemp requires little fertilizer, and grows well almost everywhere. It also resists pests, so it uses little pesticides. Hemp puts down deep roots, which is good for the soil, and when the leaves drop off the hemp plant, minerals and nitrogen are returned to the soil. Hemp has been grown on the same soil for twenty years in a row without any noticeable depletion of the soil.

Using less fertilizer and agricultural chemicals is good for two reasons. First, it costs less and requires less effort. Second, many agricultural chemicals are dangerous and contaminate the environment - the less we have to use, the better.
