Things most important to you!

• Air to breathe picture that!
  You would last minutes without it.
  
• Water to drink especially in San Diego See 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.
