That is quite a statement from a man who has spent his life traveling the world and studying the commodities markets. The fact that China and the emerging markets are consuming more natural resources and food supplies than the world can effectively produce could cause all of our natural resources to remain at historical lows for some time to come.

One example of this is another report that came out earlier this month from the U.S. Department of Agriculture. It said that the "U.S. wheat stockpiles may shrink to the lowest level in 59 years due to robust demand for the grain following two years of weak harvests worldwide.

The USDA projects wheat supplies for the 2007-2008 crop year will fall to 307 million bushels, down 55 million bushels from its estimate last month, due to the fast pace of export shipments. Foreign appetite for the country's wheat has surged after poor weather damaged harvests around the world this year. Record high prices have done little to dampen demand.

With the prospects of this bull market continuing well into the future, I wanted to take a look at a few ways that investors might be able to take advantage of the situation.

The first way is to obviously be directly involved in the futures market of these commodities. However, that can very risky if you are not an expert or dealing with an expert in the field. The other ways would be to buy specific companies that are involved in the agriculture business, like Monsanto (MON - commentary - Cramer's Take), Bunge (BG - commentary - Cramer's Take) and Agrium (AGU - commentary - Cramer's Take).

The other way would be to use an exchange-traded fund that trades the commodities for you. The one I'm aware of that has been around for a while is the PowerShares DB Agricultural Fund (DBU - commentary - Cramer's Take). It has been trading since January of 2007.

The fund is based on the Deutsche Bank Liquid Commodity Index -- Optimum Yield Agriculture Excess Return™ (Index), which is composed of the futures contracts of a wide variety of agricultural commodities, such as corn, wheat and sugar. Let's take a look at its chart and see what the ETF is doing right now.

You can see that the shares were consolidating for several months before breaking out on heavy volume in late September. The price has since pulled back to the 50-day moving average, and now looks like it is ready to attempt another move higher.

Buying exchange-traded funds in lieu of participating in the futures or options markets does not completely limit your risk. Just like anything else, you need to protect yourself with protective sell stops underneath logical support areas. In this case, I would probably use the October low of $27.61.
