I think the correct answer is B
Irreversible climate change and damage to marine and land life/humans.
Most fish need a minimum of 4 parts per million of dissolved oxygen in seawater to survive for long periods.
<h3>How can you mesure dissolved oxygen in water?</h3>
Dissolved oxygen (DO) is estimated utilizing a disintegrated oxygen meter or DO meter. The best strategy is to take the estimation in the field simultaneously every day, in light of the fact that DO fixations can shift all through a 24 hour time span.
Testing disintegrated oxygen (DO) in water is either estimated by means of substance examination, for example, a titrimetric technique, electroanalytical utilizing galvanic and polarographic tests, optical broke up oxygen, and colorimetric strategies.
In any case, present day procedures basically utilize electrochemical or optical sensor techniques.
The Winkler Method is a procedure used to quantify broke up oxygen in freshwater frameworks. Disintegrated oxygen is utilized as a mark of the wellbeing of a water body, where higher broke up oxygen fixations are corresponded with high efficiency and little contamination.
Disintegration of natural material,Bacterial oxidation of dead natural material consumes oxygen. This likewise makes sense of the relating expansion in supplement levels underneath the epipelagic zone.
