Synthesis & Plan

My general topic that I have been researching is why do diamonds cost more than water. I have broadened my topic into different ideas. Some of my ideas are should people want diamonds, are diamonds really worth their cost, and why people need to conserve water now. These are some of the ideas that I have discovered this far. All of these topics that I have researched are connected to my original topic, why do diamonds cost more than water? I am interested in learning more about why diamonds cost so much compared to water. I have found some answers to my questions but not all. Some questions that I plan on answering is why water costs more in some places in the world than in the U.S. I would also like to research if their are alternate uses to diamonds instead of just jewelry. I would also like to research what we can do to better distribute scarce resources. These three topics that I plan on researching are going to help me figure out why diamonds cost more than water. I have found out so much information about diamonds and water. I have an idea of why diamonds cost so much and why water is so cheap, but i want to find out more.
