Lichen are a good pollution indicator because they get their water and minerals from rainwater and the atmosphere. This makest lichen extremely sensitive to the atmosphere. As a result very few lichen grow in or near large cities with heavy pollution.
pollution creates clouds so when it rains... we get good crops. without pollution we won't have clouds if it doesn't, go to www.google.com
An indicator is something, rather it be a person, animal, or plant, that determines how much pollution is in the area. Birds are a good indicator of air pollution.
* bryophytes are good indicators of environmental pollution, particularly eutrophication where u have more calcium and nutrient content in water. * they r good indicators of soil PH * Bryophytes help prevent soil erosion * they are excellent seedbed for most coniferous trees * they are good source of fuel
because they start to die when there is water pollution and that tells us that there is water pollution
No it is not. It harms the environment and kills marine life. If you think water pollution is good, it's not.

Water Pollution is NOT GOOD! It could be, ina way, that we clean our cities and stay alert at the fact that the water is polluted. But overall, it's definately(sp?) NOT GOOD!

Indicators of good water quality include clarity, odorlessness, absence of floating debris or pollutants, and a balanced pH level. Additionally, the presence of diverse aquatic life and the ability to support recreational activities suggest good water quality.
Pollution is all around people , and effects the air , and water.
Plants purify air composition by absorbing CO2 and releasing Oxygen. By way of transpiration plants add humidity in the air and broad leafed trees also help in reducing suspended particulate matter from the air. A good number of aquatic plants absorb heavy metals from water. Thus plants help us fighting pollution in many ways.
