It seems that this organic material brought in from the sea may be causing symptons of asthma in coastal areas of New Zealand, I would be very interested in any thoughts you might have on the subject especially as I would think this might also apply to the coastal belt of California, Yours sincerely, s AT ame oes Encl, ‘L'of TMosy'™
