There are many reasons why geology is essential in life and to civilization. Think about earthquakes, landslides, floods, droughts, volcanic activity, ocean water currents (el Ni??o), kinds of soil, fuel oils, minerals (gold, silver, uranium), and the like. Geologists study all of these concepts. Thus, the research into geology plays a crucial role in todays modern life and civilization. If you're at a part of your lifetime that you realize you are heading within the wrong direction which means you're producing the wrong results then simply generally do the opposite of the you're doing at this time. Trust me as a result a whole lot of difference and you'll almost see small and/or big result quickly. I know this is easier said then done but when you add courage and persistent practice to your constant thought pattern that's saying "it's time for you to increase the risk for necessary changes" then I'm sure you will make great progress in living an even more happy and fulfilled life. Long before there have been machines to work out on and competitive sports to stay moving and before wars were being fought, man didn't think about conditioning as a way of keeping healthy. He simply knew if he didn't hunt, he wouldn't eat if he didn't run, something would hunt him. They were a down economy that focused simply on survival.
