 It's very important when you study things and you're interested in documenting perhaps changes to the earth because this will impact food, water and the lives of people in many ways, perhaps through more severe storms or higher frequency of severe storms or maybe in changing precipitation patterns where some areas become very wet, others very dry. So it's really important for the continuation of our species living on this planet in a responsible way to study things like this, to be looking ahead 10, 20, 30 years and seeing things we will need to change so we don't screw up the earth.
