The Great Lakes are five interconnected bodies of freshwater on the United States-Canada border. Some scientists estimate that if wind turbines (tall towers with rotating blades propelled by the wind) were built in the Great Lakes, the turbines could provide electricity for up to 210 million homes. That and the additional economic and ecological benefits that have been identified have convinced many people to support plans to build turbines in the lakes, several kilometers off their shores.
First, bringing wind turbines to the Great Lakes would have great benefit for the local economy. Installing just a few hundred turbines in the lakes would create tens of thousands of jobs in the area. One Canadian province bordering a lake estimates that this would add several billion dollars to its economy over a ten-year period.
Second, the Great Lakes, precisely because they are freshwater lakes, have an advantage over other places where wind turbines are used. Many wind turbines have been built in the ocean near the coastline of some countries, and maintenance costs for these turbines have proved to be high; the salt in ocean water has a corrosive effect on the turbines. In freshwater lakes such as the Great Lakes, corrosion to the turbines is not an issue, so maintenance costs would be kept low.
Third, the wind turbines would help reduce water use. Currently, coal and natural gas power plants use billions of liters of water from the Great Lakes as part of the process by which they produce power. Much of this water cannot be returned to the lakes. In fact, it is
estimated that if wind turbines replaced some of those coal and natural gas power plants in producing electricity, up to 9 billion liters of water could be conserved.

Local governments have limited budgets to spend on enriching residents’ lives. Supporting arts programs like concerts and museums offers cultural engagement, while funding recreational activities like hiking trails and parks promotes healthy lifestyles. As students who appreciate culture and wellness, let’s discuss whether local funding should support arts programs or recreational activities more. Which do you think better serves the community and why?

I think local governments should prioritize spending on outdoor trails and parks rather than arts programs like museums and concerts. More people would use and benefit from improved recreation spaces than arts venues. If fewer residents are interested in the arts, they won’t attend museums or concerts even if government funds them.
Paul
I believe local governments should actually prioritize spending on arts programs like museums and concerts rather than recreation. Precisely because fewer residents are inherently interested in the arts, public funding is essential to sustain these cultural institutions for the minority who appreciate them. Without support, access to the arts will decline and society will lose these enriching, enduring outlets for creative expression.
