Personal Reflective Learning Journal Wesley Barbosa CSU Global 9/10/2011 After reading the first chapter of the text book and taking the Ecological Footprint Quiz I really had a refresher about how I impact the environment. I have often thought about the environment and my impact on the environment and have felt that I have done a pretty good job of doing my part to help the environment. In the Ecological Footprint Quiz I learned that I use almost 5 earths! After I earned this and thought about the ways I could reduce my footprint I retook the

quiz and it was only reduced by less than one earth. I feel like I need to do more but I certainly face a tradeoff that I am not sure I am willing to meet. For now I will start to be more economically friendly by preparing my own meals, not only is this good for the environment but it will make me healthier at the same time. I am also planning on starting a compost pile this week and will keep you updated in this journal as I progress on this journey. I would like to ride my bicycle more often and save of fuel as well has reduce my impact but at this point in my life I am unsure of the possibility as this would require a substantial amount of time which I am not sure I can incorporate into my life. Even though doing all of these activities will only reduce my earth usage a small amount I feel it much better than doing nothing. If everyone could reduce their earth usage by one whole earth together we would make a huge impact on the human impact on the globe. 9/17/2011 After reading chapters 2-4 in the textbook and participating in this week’s discussion I realized how important the sun, nutrient cycles and gravity are to support all of the life on earth. It is very interesting to me that what sustains life on earth depends on only three factors; flow of energy, cycling of nutrients (matter), and gravity. The first two really made sense to me but I had never considered the importance of gravity. The sun is the main form of energy for the planet although plants and animals also create energy. The sun lights and warms the planet, powers matter cycling, drives climate and weather patterns and supports photosynthesis. Nutrients must be recycled many times. Carbon cycling is particularly important to sustain life. Speaking of which I have started my compost pile and feel even better about it after this week’s reading. Carbon is used as the building block in every organic molecule and is considered the backbone of life. All of this would not be possible if it was not for gravity as gravity holds the planets atmosphere and

causes a downward movement of different chemicals in a cycle. Without gravity the biogeochemical cycles would not be possible. I also learned that humans have had a huge impact in disrupting biogeochemical cycles by extracting resources and using them. This greatly speed
