I believe that we should not become so greedy that we would harm others, or our surrounding environment. My gemology teacher said that in a business transaction every party should walk away happy, and that this is how you would know that it was a successful business transaction. Ethics.
I urge you to be responsible when working with the land. Please, be respectful and rational when extracting resources from the Earth. Everything we do effects the surrounding environment in some way. Think before you act. Thank you.
