World population and water
With more and more people in the world, more and more water is used. In fact, water use is growing more than twice as fast as the world’s population! As a result, getting good, clean water is becoming a problem in many places.
A lot of water is polluted and in many areas people have to walk a long way to get clean water for daily use. More than 3.4 million people die each year from drinking and washing with polluted water. So let’s do everything we can to stop the pollution and save water.
Choose a country or town which interests you. It could be your home town.
Decide the points of time you want to look at – for example, now, ten years ago and ten years from now.
Research the population of your place in those years. Write your notes carefully.
Work in groups. Prepare to make your graph.
Decide how you want to make your graph.
Draw it and color it. You can also make it on the computer.
Label it clearly.
Make your graph and present your graph to the class.
In the graph, we can see how the population in the town changed between 1900 and 2000. we can see the population going up the vertical line and the years going across the horizontal line. The graph shows the population increased by more than one hundred percent from two and a half million to
five million in one hundred years. At first it increased very slowly, but after 1945 it increased much more quickly. From 1990 to 2000, the population even increased by one million. The town itself also grew in size during this time.
