WATER  STRESS Every item  that we use needs  water for production Domestic   bathing, flushing, washing,  cooking, drinking… Agriculture  People require  food to eat Industry  Increase demand  for goods Increase in Population  Power  water evaporation from reservoirs of large hydro power projects
'It's not just excess consumption.  Man is creating further water stress by polluting fresh water sources.'

More food required to feed the growing millions'   Increase in Population  Converting forests into croplands  Fewer Forests Water Pollution Fertilizers and  pesticides
Fewer forests Topsoil washed out into freshwater sources and reduced recharge of water into the ground
Agriculture Fertilizers  and  pesticides  easily dissolve in water.  They enter surface water sources  through  rainwater and   irrigation   runoff  and also  percolate into the  ground  to contaminate groundwater sources.

A game to check how much you have learnt Play   LINK TO THE GAME
Divide the class into 5 teams. Team A   selects 2 people who will guess the answer.  These  2  people turn their face to the wall or go out of the room, so that they can’t see the clue.  Play
Team A have to act out the clue for the 2 guessers.  Either all members of Team A can act it out (very boisterous, but all children are involved) or a representative is selected to do the acting.  The other members of  Team A   (and the rest of the class) see the clue.
If the guessers got the right answer in 30 secs, they get 5 points If the guessers get the right answer in 30 secs, they get 3 points  Otherwise   The chance then goes to  Team B  and so on. Rules:  No mouthing of words
Round 1 Team A – Agriculture Team B – Domestic use Team C – Reservoir Team D – Population Team E – Industrial production
Round 2 Team A –  Energy Demand Team B – Over exploitation Team C – Urbanization Team D – Lifestyle Team E – Lake destruction
Round 3 ,[object Object],Team A  –  Fertilizer runoff Team B  –  Sewage disposal Team C  –  Industrial waste water Team D  –  Pesticides
Round 4 Team A – Idol immersion Team B – Tourism Team C – mining Team D – Conflicts Team E – Animal products
