What things are most important to you?????????????

• Air to breathe picture that! You would last
  minutes without it.
• Water to drink especially in San Diego, imagine
  the Salton Sea-wer! California Development
  Company, land and water speculators, created it
  in 1905. It is now 25 saltier than the ocean!
  Serves as nesting, feeding, breeding site on
  Pacific Flyway after Colorado River delta was
  destroyed by water diversions. Now a sump full of
  fertilizer, pesticides, selenium and other salts.
  You might last a few days without water.
  
• Talk about a cash crop! Farmers buy water from
  Colorado River for 17.50/acre foot and sell it
  to San Diego for 275/acre foot!
• Food to eat good and cheap You might last weeks
  without it.
• But that has changed, now obesity is even
  a CA problem.
• Sex, well get to that next!
