How would you revise the simulation so users can evaluate the role of human activity in the pH of the ocean? what variables would you add or change in the simulation to accomplish this?
(PLZ HELP WITH 2ND QUESTION)

I would increase the temperature of the ocean and lower the percentage of pH so that users see how the ocean is affected by human activity, human activity causes the pollution of the air that causes CO2, which leads to all that CO2 is absorbed by the seas thus increasing the amount of acidity which brings as a consequence the increase in temprature and the dissolution of coral reefs.

5 Steps to Simulation

Step 1: Decide on the purpose of the simulation and what performance metrics you want to monitor. Very rarely will you need to simulate your entire business. ...

Step 2: Build a first Pass Simulation. ...

Step 3: Calibrate Your Simulation. ...

Step 4: Analyze the Results and Select the Best Alternative. ...

Step 5: Share Your Simulations.

I would add divers or boats. Boats that catch fish lower their population and can increase pollution. Snorklers and divers tend to lose things in the water again increasing water pollution.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.
