The oldest living organisms in the world are the Bristlecomb pines of the mountain regions of California and Nevada. They can live for greater than 5,000 years and in the course of their lifetime they will see 1,000,000 sunrises!
Why build reservoirs when you can use nature's own?
Why build reservoirs when you can use nature's own? Natural water reservoirs, "aquifers", may contain
bacteria which destroys dangerous viruses. If this is the case,
these natural reservoirs could be used to store sewage, storm water
run-off and other contaminated waters which cannot be allowed to
drain into rivers. Eventually, these natural aquifers could help
convert impure waters into drinking water. 29 JANUARY 2000, P. 14
