LETTERS The Hadza Not long after reading the article on the Hadza of Tanzania, I heard John Lennon's "Imagine" on the radio, and several similarities struck me. Lennon sings of a new world where there is no religion, no countries, no possessions, greed, or hunger, everyone sharing the world and living life in peace. The Hadza people have little religion and are unaware of the rest of the world, let alone separate countries. They have few possessions and don't worry about famine. Everyone shares the land, living in peace with other tribes. It makes one wonder if Lennon channeled his possible African ancestors while writing the song. ANDREW SHARO Wayne, Pennsylvania My heart goes out to the Hadza. It is sad that people who are hurting no one have little choice of how to live because some more powerful people now want their land. How many humans alive today still know how to knap a stone tool or start a fire with a stick in 30 seconds? Western culture and resource use, which many now believe to be unsustainable, has been adopted by most of the world. Maybe it would be wise, just as a sort of insurance policy, to leave the Hadza alone. We may never need the kinds of skills the Hadza still possess in order to survive another 10,000 years. But what if we did? GAIL STUMPF NSENTIP Fort Bragg, California The Hadza are our past, and we are, on a technological time line, the latest advanced human society. During our travel in time from there to here, I wonder when, if ever, our ancestors had the optimal balance of health, security, comfort, and the "Hadza effect." No doubt this effect is imprinted in all humans; it has just gotten buried in all of our schedules, time crunches, emails, etc. While modern societies have minimized what seemingly plagues the Hadza, your excellent article (and those A note about risk: The Fund is subject to the risk that stocks that com- prise the water-related sector may decline in value. The stock markets in which the Fund invests mayalso experience periods of volatility and instability. In addition, shares of the companies involved in the water sector have been more volatile than shares of companies operating in other, more established industries. Consequently, the Fund may tend to be more volatile than other mutual funds. Lastly, foreign investments involve greater risks than U.S. investments, including political and economic risks and the risk of currency fluctuations.
