Ericka McGhee 4/9/26 - Blue Gold: War on Water (in class)

Today in class, we watched some of a documentary about the world's water supply. During the first half of this documentary, they explained that the world's water supply is diminishing. Even though people had thought they had found ways to help, it turned out they were only hurting the water supply. They also mentioned that only 3% of the world's water supply was freshwater. I found that very interesting because of how much of the earth is covered in water; only a small percentage is actually fresh. Another really interesting thing I found out was that water pollution has been linked to low fertility in men and women. The documentary explained how the groundwater is one main source we use to get our water. This has caused a lot of places to sink into the ground, such as Florida and Mexico City, for example. Mexico City has taken all of the groundwater in some areas of the city, causing them to have to move farther and farther away from pumping sites. It was stated that we are pumping 30 billion gallons of water each day from the earth. There are ways to stay within the sustainable limit, but we are not staying within that.

Kip Redick Student's Free Choice Example

  Here is an example which would be a free choice entry.    Since last semester, I have been on e-board for the Green Team at CNU. I am the sustainability and research chair and my role is to make campus more green and sustainability which is challenging because CNU tends to be stubborn and not want to change. Although I have been struggling to do my job and change things, I have gotten so much insight from the other Green Team members because we come from different customs and view points. We have bonded over our love for the environment and our need to change. We have our own rituals were we try to connect with nature through meditation, yoga, and reciting poems and sharing ideas. We have a big/little system called Oaks and Acorns in order for new members to know how the group works and become close to each other. Green Team is not dominated by one class, one religion, or one race. That is why I love this organization so much. We are all accepted and brought...

Kip Redick Example of a Student's Choosing

  This is an example of a topic of the student's choosing.   During the summer of 2022, I attended an environmental encounters trip to Iceland with Dr. Kip Redick, Dr. Joe Balay, and 14 other students. It was a two week trip, but those short two weeks completely changed my life. I learned about more things than I thought was possible in 14 days, and I've never been more interested in learning before. It completely opened my eyes to a whole new perspective, on how the world should live, and what the environment should look like. Everyone was so kind, and they are the most environmental conservative countries.  While there, we did many different activities, including hiking on a glacier. It was so fun, but exhausting and kind of sad at the same time. It was obvious to see how much the glacier have had melted in the past years due to global warming, as there was a large glacial lake at the bottom with melted ice, and the glacier was all rock and sediment before w...
