In 1982, the World Heath Organization (WHO) brought together a panel of cancer pain experts to discuss this worldwide crisis. This group reached the consensus that relief from cancer pain is an appropriate goal for most patients. The WHO placed a high priority on the relief of cancer pain, and another meeting was held in 1984 that resulted in the first publication of Cancer Pain Relief in 1986. ... 

The World Heath Organization (WHO) reports that drinking unclean water causes diarrhea that kills 1.6 million children under the age of five each year. An estimated 1 billion people in the world do not have access to safe, pure drinking water. By the time deaths attributable to diarrhea, cholera, schistosomiasis, and other diseases spread by contaminated water or aggravated by the lack of pure water for personal hygiene are included, the worldwide death toll is estimated at 9,300 people per day or over 3.4 million per year These numbers are hard to fathom for most Westerners, but they are far too easy to grasp for those living in certain areas of Asia and Africa where such deaths are, unfortunately, almost routine.

From the foregoing, it can be seen that the amount of silica annually fixed by marine organisms (ca. 25 Pg y ) is approximately balanced by the amount annually dissolved from their siliceous tests (ca. 24 Pgy" ). Moreover, these quantities exceed by more than an order of magnitude the yearly amounts of silica contributed to the world ocean from external sources (rivers, interstitial waters, etc.) or removed from it by burial in marine sediments (Heath, 1974 Wollast, 1974). Thus, it is apparent not only that the marine silica cycle is biologically controlled, but also that the biological subcycle of the marine silica cycle acts as a quasi-closed system.
