Article's purpose: Water's importance for life and humanity.
rewrite with purpose in mind (what is wrong with it now? has this been discussed?)
?? Small portions of water occur as groundwater (1.7%), ..glaciers ..ice caps ..Greenland (1.7%) ??
Discuss the dangers of water, including brief discussion of reactive properties and include its NFPA diamond (http://en.wikipedia.org/wiki/NFPA_704).
Expand appropriate short statements into full paragraph.
re-organization toward this purpose
missing topics within scope
Under missing topics; a substance we clearly know so much about, it seems to me it perhaps should have the chemical box/medical/physical data as this would be quite baseline?
Add a section on water-based power (hydroelectric, wave, tidal etc).
Water on other planets
consider deletions with this purpose in mind
spin-off topics tangential to scope
change types of water to forms of water.
please include the role of comets and meteors in bringing water to earth
