Water Pollution. The Contamination of water with undesirable substances which make it unfit for usage is termed water Pollution.. 

Scene 5

The Contamination of water with undesirable substances which make it unfit for usage is termed water Pollution.

SOURCES OF WATER POLLUTION. Most of Water Pollution is man made It may also occur naturally by addition of soil particles through erosion animal wastes and leaching of minerals from rocks.

INORGANIC POLLUTANTS.  They include fine particles of different metals, chlorides, sulphates, oxides of iron, cadmium, acids and alkalies.. 

Scene 10

   They  include fine  particles of  different   metals,  chlorides,  sulphates,  oxides  of  iron,  cadmium, acids   and   alkalies.

ORGANIC POLLUTANTS.  They Include oils, fats, phenols, organic acids grease and several other organic compounds. 

Scene 11

 	 They  Include oils, fats,  phenols,  organic  acids  grease   and several  other  organic   compounds

MARINE POLLUTION.  Ocean are the final sink of all natural and manmade pollutants. Rivers discharge their pollutants into the sea. The sewage and garbage of costal cities are also dumped into the sea. The other sources include, discharge of oils, grease, detergents, and radioactive wastes from ships .. 

Scene 13

   Ocean  are  the  final sink of all  natural  and  manmade    pollutants.  Rivers  discharge their pollutants  into  the  sea.   The  sewage  and garbage  of costal cities  are  also  dumped   into  the  sea.  The  other  sources include, discharge of  oils,  grease,  detergents, and  radioactive  wastes from   ships .

THERMAL POLLUTION.  Thermal Pollution of water is caused by the rise in temperature of water. The main source of thermal pollution are the thermal and nuclear power plants. The power generating plants use water as coolants and release hot water into the original source. Sudden rise in temperature kills fish and other aquatic animals..

Scene 15

CAUSES OF AIR POLLUTION. Carbon dioxide-this happens because of Deforestation and fossil fuel burning. Sulfur dioxide –Due to the	burning of sulfur containing compounds of fossil fuels. Sulfur oxides- very dangerous to humans at a high concentration. Sulfur in the atmosphere is responsible for acid rain..

Scene 17

INDUSTRIAL WASTE. Plastics factories, chemical plants, oil refineries, nuclear waste disposal activity, large animal farms, coal-fired power plants, metals production factories and other heavy industry all contribute to land pollution.. 

Scene 18

Plastics  factories,  chemical plants, oil  refineries, nuclear  waste  disposal  activity,  large   animal farms,  coal-fired  power  plants,  metals production factories and  other  heavy  industry all  contribute  to  land   pollution.

Scene 19

SOURCES OF NOISE POLLUTION. Transportation systems are the main source of noise pollution in urban areas. Construction of buildings, highways, and streets cause a lot of noise, due to the usage of air compressors, bulldozers, loaders, dump trucks, and pavement breakers. Industrial noise also adds to the already unfavorable state of noise pollution. Loud speakers, plumbing, boilers, generators, air conditioners, fans, and vacuum cleaners add to the existing noise pollution..

GLOBAL  WARMING  AND  THE  GREENHOUSE   EFFECT

DIFFERENCE BETWEEN GLOBAL WARMING AND THE GREENHOUSE EFFECT. 

Scene 22

DIFFERENCE BETWEEN  GLOBAL   WARMING  AND  THE GREENHOUSE   EFFECT

Global  warming  refers  to  a  rise in the   temperature  of	 the  surface  of the   earth. The  Greenhouse  Effect  is  a  process  by  which   thermal  radiation  from  a  planetary surface is  absorbed  by  atmospheric greenhouse gases,   and is   re-radiated  in	 all directions.
