The Great Lakes are the single largest system of fresh water on the Earth’s surface, containing nearly 21 percent of the world’s fresh water supply and over 84 percent of North America’s. Millions of people rely on these lakes to supply them with drinking water, food and fuel. Even though Michigan and other states in the Great Lakes basin have more than enough water at the moment, this may not always remain true considering the effects that the Earth’s changing climate is having on them.
According to an article published in the Midland Daily News this past March, the overall effects of climate change in the Great lakes basin could cause some serious problems such as lower water levels, more severe storms and hotter temperatures. These factors have already been destroying many of the Great Lakes wetlands and other natural habitats. The gradual change in climate is also causing “decreased ice cover” which means heavier and harsher rainfall for the Great Lakes Basin. While looking for more information I was expecting to find shocking results that showed just how much the Great Lakes water levels were lowering, however as of right now some results are showing otherwise. Another article I read covered by an ABC affiliate news channel in Cleveland, OH talked about how the water levels of Lake Erie are currently above normal records, instead of below like many had anticipated. In fact the average level of water for Lake Erie for the month of April is 174.22 and as of April 1st, 2012 it was 174.36. Even thought that doesn’t seem like a huge increase, it was certainly surprising to me.
Another One of the main problems discussed throughout the Midland Daily article revolves around the Earths’ ever increasing global population and how more food will need to be produced to keep up. In fact by the year 2050 the amount of grain produced worldwide will need to double in order to sustain the growing number of mouths that need to be fed. If ours agricultural ways don’t become more “efficient” by this time the water used for agricultural needs will have to double too, which is where the problem lies. How can we use twice as much water as we do now for food, if our water supply continues to dwindle down little by little every day?
