I have been doing some research on Tesla lately, and have found that the amount of Lithium Ion Tesla uses in their batteries is astounding. The resources used to make these batteries will eventually become depleted, becoming more and more expensive, driving the price of all battery operated goods upward.
However, Elon Musk is the biggest name behind the driving force to colonize Mars. I have been curious as to why he would want to colonize Mars, and I believe I have found a reason. Elon wants to be the first to colonize Mars, and monopolize the mining industry there, and finding a what to efficiently transport the resources.
Elon Musk is simply another greedy billionaire. A bully of humility.
