Haven't seen too many Swamps that are not Acidic! Why? Because of decaying matter that releases CO2 back to the atmosphere! Cause and effect, not effect and cause! Own a pool? As a guard you should know what causes a pool to become Acidic, organic martial, and not CO2! Why won't you address the .0046 or 46 thousands of a percent of the atmosphere from the top to the bottom of Death Valley! I don't think we have to worry about the oceans becoming Swamps anytime soon! It is a natural swing that we now can measure and 300 years ago we couldn't and didn't care! We are too young at observing, but smart enough to know where funding comes from! Don't kid yourself! Your teachers are slaves to the funding they all claimer for! Your problem is your young and easily persuaded, got to keep those grades up! So a 4 one thousands of a percent is going to kill us we are already done!
