Answer:
In the l learned three main three main things that influence the freshwater available on earth: PH, pollutants and factory usage.
Step-by-step explanation:
The first thing, PH, is really influenced by the way the pollutants are discarded, for example, if a factory decides to throw their pollutants inside a very good and not polluted river, this river will change how it chemically works, and through that, the PH will change, it can turn into a more acid or basic river, depending on the components that were thrown there.
I learned from conducting this lab that every act of the human race affects the environment as a whole, and the main thing to pay attention to in this experiment is that, everything is linked to one another in some way.
