** The pH in your H 2 O  ** Healthy* Getting Worse*Dead

Neutral water is only pure water. Most organisms in a river or stream can tolerate slight changes in pH, but the acidification of fresh water bodies can greatly reduce an ecosystem's population. Some streams are only acid for a short time. The pH in water change over time, it can even change in a course of a single day. The pH scale normally falls during the night and rises during the day time. pH also changes as new fish come and others go.



__** Effects of acidification in our wildlife: **__ -fish killing -decreases in insect populations -loss of bottom dwelling organisms

__** Interesting facts: **__ -When the ocean has a high or low level of pH it can affect our economy. There is $4 billion of harvested fish in our oceans each year. Many organisms can't build strong shells or skeletons. -When the pH level is low the ocean has lower frequencies, which makes everything noisier. There are several organisms that communicate over long distances, and with lower frequencies they will have distractions.
