Water

This week in geography class the main topic of discussion has been about water and agriculture. First we began to talk about where water bottles come from. Water comes from taps, bottles, lakes, and any type of way water is distributed to people. We talked about two types of watersheds: The Mississippi Watershed and the Great Lakes Watershed. Pleasant Prairie recieves its water from the Mississippi Watershed and Kenosha recieves its water from the Great Lakes Watershed which comes from Lake Michigan. Water may either come from the tap or be purchased in bottles. It is fact that about four billion people do not have access to clean drinkable water on a daily basis. There are three types of filters that clean water. The first filter is a sand filter, the second filter is a ozone filter, and the third filter is an aquafir, which is fully saturated rock. In many places water contributes to that areas temperature. In Kenosha the Great Lakes keep us at a moderate temperature.
This week we also got into groups to decide weather or not to build a recreational lake in Arizona. We disscussed many advantages and disadvantages to the City Council who the developers were trying to persuade. The other two groups came to the conclusion that building the lake would be a bad idea due to the cost, the taking away of drinking water, and the algae problem. The City Council voted the lake to not be built, but in reality we actually found out that the lake really does exist.
