There is a lot of discussion about the issue of the best material between glass, aluminum, and plastic. My decision is that glass is the best choice.

My decision is based on the following evidence. First, in the manufacturing process they use recycled water to cool the glass and other materials from the manufacturing process. Secondly, glass is a good choice because it can be used over and over again Also, it is takes less energy to melt already manufactured glass. Lastly, during the manufacturing process, waste (recycled) water is used to cool down the glass and the other leftover waste. This will prevent the usage of too much water.

People who disagree with my decision might say that $0.10 are too expensive for a glass bottle. I think that the money is well spent. This is because it is better for the environment and the future for our planet.
