Chapter 1

http://www.physorg.com/news170519675.html

Summary:
The article talks about our most valuable resource, water. The article states that water first began to diminish in Australia, between 1993 and 1996. They have had low rainfall the past several years, and the drought is caused by both historical trend and climate change predictions. Dr van Dijk, senior CSIRO researcher, has been researching Australia's water resource with the first ever national and comprehensive analysis of 30 years of on-ground and satellite observations. He says that what makes the situation worse than it is, is that the sixties and the seventies were way wetter than it is now. They are afraid Australia might run out of water resource.
Connection:
The connection between the article and chapter 1 in our textbook is scarcity. Chapter 1 talks about scarcity and what scarcity really is. Because everything is scarce, we have to make a decision on how the commodity will be used. Water is most important thing in our life, and now water is becoming scarce. The demands for water are way too high with the supply being limited. On average, each Canadian uses 7100 litres of water a day. The demands for water will continue to rise as the supply for water continues to fall, we have to find a way to get our supply of water back up or else we'll run out of water.
Reflection:
Canada has 14% of the world's lakes and 9% of the world's river flow, yet water is becoming scarce in Canada. I think that water is the most important thing in our life. Without water, we cannot live. With the supply of water continuing to diminish, we have to cherish our water supply. We can do that by not wasting water, and also not polluting the water that once used to be clean. With the demand for water continues to rise, we must seek a way to save our water, that is, perhaps finding a way to make the undrinkable water drinkable. The question now is, how long do we have before the drinkable water is depleted.
