Dear  Jessica, In answer to your question, what can a diver do, you 
might suggest that they do not urinate in the water, do not wear 
sunscreen, and do not exhale,(exhaled breath contains between 30,000 
and 40,000 ppm CO2). Actually there is little we can do regarding CO2 
that would significantly change its concentration in the air or water 
in the short term.  Ove Hoegh-Guldberg is correct when he said in 
Mother Jones Magazine, "It's unwise to assume we will be able to 
stabilize atmospheric CO2 at levels necessary to reduce or prevent 
ongoing damage to marine ecosystems." Most changes due to CO2  are in 
deep water or in shallow estuaries, not in coral reef areas. Deep 
water corals below the compensation zone have always dwelt with 
higher levels of CO2. Gene
