Worry warriors out of their tree over the reef

The worry warriors are fearful of reef damage from polluted runoff from land 
Lesson 1  Don't  listen to people quoting scientists ( people will quote those who agree with them) ; listen to scientists themselves .If you are not a scientist you will often need to LISTEN long to a range of them because on these complex questions , they don't always agree and it takes years to gain competency over the ecosystems ( cf plant or animal ) involved .
What many citizens do not know too is that much so called independent science research on environment has been captured by the politically correct . eg the cuddly stuff . You will read here about soil -- where are the soil scientists in YOUR state Utopia group ? 
 Should you trust someone whose just outta school ?(
Should you trust those who claim to know all the important things cause their facts are at their fingertips on a computer playing  with atmospheric physics modelling and because they are paid specifically to come up with more worries re climate ? 

Lesson 2  The solution to pollution is often dilution . Make up you own minds and study the flocculation after events . 
Lesson  3   Watch Utopia . People trying to do/help  the experts  do his/her job is driving the experts and honest brokers mad 
 
Whose a good scientists  to trust? One who admits he often knows more and more about less and less  

THE REEF  ( Great barrier reef Australia in particular)  Note nearshore ( discussed here ) can be different from wavecut platforms  etc 
The reef like any ecosystem is a complex but resilient beast , Like all ecosystems it requires a number of scientists to understand  the actual boundaries of each animal or plants, resilience and how it works both individually and together; the stresses in lifecycle year, season and circumstance are full of variables. 

WHAT WE DO KNOW   about near shore effects from streams .

1. Water bodies are usually  precariously infertile, That is , they struggle to maintain  nutrient recycling near the surface because gravity operates on both solids and solutes (the critical unseen particles )  
2. Life in water is dependant then on phases A- phases of growth and decline ; B phases of depletion and infertility ; C phases of dependency ( algae feeding fish bacteria protozoa zooplankton etc )  D phases of regeneration ( seeding spores and high substrate  availability - from another phase ; phases or death or threat ( wind and calm ) 
3.  Fresh water entering salt water can release large amounts of much needed food  but the various phases of growth and decline vary greatly with space and time , A turbid flood does not reduce light penetration in seawater for long as high salts flocculate the clays .( generally) 
4. In general and in the big picture,   the reefs can benefit greatly  from highly nutrient rich  from land  runoff. They after all often running near empty on some equations of productivity and growth . 
5. While soil could impact negatively on the growth of algae and various other species,  the soil particles do not remain suspended for long and their attendant cation site attachments are welcome with little likelihood of deep deposits on reefs 
6. Do not panic . even the most turbid water coming from land is soon  flocculated in sea water .
   
   Take the fake news off the news please   we don't watch the ABC much now anyways as they employ few practical scientists and follow the weight of the political moment in the direction of  ignorant fear mongers and cynics.
