Another human impact on ecosystems stems from the production of nitrous oxides (NO2).
Mostly, by us humans, its created by the use of fertilizers and vehicular emissions.

NO2 changes the pH levels of water and soil. One common term you may have heard of is Acid Rain. Humans have a skin pH level of basically 5.5 which will kill certain bacterias in order for us to survive. Likewise of water and soil so that certain ecosystems can survive in them.

For example, fish eggs need balanced pH levels. If this is thrown out of balance fish eggs won’t hatch…

Other fishes that are able to survive in more acidic waters will take over ie: those jelly fishes that are now closing beaches and seen in bodies of waters never seen before. It’s another reason for the bleaching of our coral reefs in which all living species that used to adorn our eyes are now nothing but dead sheaths of calcium.

It affects everyone worldwide. That’s why a Clean Air Act was created and enforced. If you’d like to do some in depth reading about the human impact on ecosystems and Acid Rain here’s a great curriculum completed at Yale

Peace.
