erosion:The gradual
destruction or diminution
of something
Because of the BMI's that are
intolerant to pollution livinging
in the stream,the water is proved
pollution free!
We wouldn't have found those
bugs if there were pollution.

7. Caddis Fly Larvae
The Caddis fly larvae is very intolerant of pollution. Meaning they cannot live in water that contains pollution
Aquatic, premature Caddisfly Adult, mature caddis fly

8. Conclusion
Since there were many Caddisfly larvae found in the brook, and caddisfly larvae are very intolerant to pollution, the water had little pollution in it. =
