We know, pollution is the introduction of contaminants intothe natural environment that causes adverse change.Thecombination of the environment due to the mixingof harmful and unwanted substances which makesthe environment impure is called environmentalpollution. The mixing of different unwanted bodiesin the different factor of environment pollutes itand degrades the quality of it. The differentactivities of human like deforestation, explosion ofbombs and so on or natural disasters like a...

Anyfive measures for the conservation and managementof water resources are:
-We should conserve watersheds and glaciers.
-Misuse and overuse of water should be controlled.
-The storage and distribution should be done properly.
-The existing sources of water should be conserved.
-Awareness about the importance of water resourcesand the way of conserving them.

We should conserve water resources because:
-Water is the elementthat every organism need for life.
-Water is used for electricity generation.
-Water is used for irrigation.

Any five measures for conservation and managementof forests are:
-Afforestation programsshould be encouraged.
-Forest fire should be minimized.
-Forest products should be used wisely.
-Deforestation should be avoided.
-Awareness about the forest and its importance.

We should conserve forests because :
-We get various important natural resources from forest.
-Forest helps us to purify the underground water.
-Forest is the sources of oxygen.

Any five measures to prevent soil pollution are:
-Chemical farming should be replaced by organic.
-Household wastesshould be managedproperly.
-Human & animals wastesshould be managed.
-Public awareness programsshould be conducted.
-Polluted water shouldn't be used to irrigate land.

Any three effects of soil pollution are:
-It has adverse effects on terrestrial organisms.
-Polluted water causesground water pollution.
-Land pollution decreases the fertility of soil.

The major causes of soil pollution are:
-Excessive use of chemical fertilizers.
-Dumping of household solid and liquid wastes on the land.
-Acid rainfall .
-Use of polluted water for irrigation.
-Throwing of non-degradablewaste.

The combination of land with the harmful substancesand chemicals or waste materials that changes thecompositionof soil is called land/soil pollution.

We can reduce water pollution by the following ways:
- Solid & liquid waster should be managed properly.
- We should keep our water resources clean.
- Afforestation around the water resources.
- Band on using chemical fertilizers.
- Awareness level should be raised at the public.

Any four effects of polluted water are:
-It cause water-borne diseases.
-Hard water cardiovascular diseases.
-Polluted water containing chemicals damages ourhealth.
-Polluted water spreads bad smell and cause airpollution.

The major causes of water pollution are:
-Mixing of drainage directly into water bodies.
- Excessive use of chemical fertilizers.
-Open deficationnear the water resources.
-Deforestation around the water resources
-Bathing of cattleand washing clothesin thewaterresources.
-Throwing the wastes into the water resources.

The combination of rivers and lakes or water resourceswith unwanted and harmful substancesthat degradesthe quality of water is called water pollution

Any three method of reducing air pollution are:
-Afforestationprogrammer should be encouraged.
-Population growth rate should be controlled.
-Solid and liquid wastesshould be managed.

The effects of air pollution are:
-It may cause headache, nausea, and allergic reaction.
-It damages buildings and historical monuments.
-It causes acid rain.
-It is the cause of global warming.
-It reduces the solar radiation on the earth.

The major causes of air pollution are:
-The dust particles released into the air.
-Production of greenhousegasses.
-Agricultural residues are burnt which causeair pollution.
-Smokes from vehicles and factoriesor industries.
-Deforestation & global warming.

The combination of air with unwantedand harmfulsubstance that degrades the quality of air is called airpollution.
The main sources of air pollution are:
-Natural sources.
-Artificialsources.

The contamination of the environment due to mixing ofharmful and unwanted substance which makes environment impure is called environment pollution.
