In chapter three “Current State Analysis” we talk about what defines the system and how you take steps to approach a problem. There is a TSR Frame work which basically breaks down where we are in the situation in time(Current State), where we want to head based on the situation that we are in(Vision), and then how we get to that place we want to be at. There are two types of drivers: direct and indirect. Direct drivers show a clear path of what the influence is without any doubt or hesitation and could be measured by different degrees of accuracy. On the other hand, indirect drivers have an influence behind them and a constant change. An example of indirect drivers could be population or technology due to constant changes. An example of direct drivers includes climate change or pollution. In this chapter Molly Cashion basically started this where people had different religious beliefs and how she made the connection saying “Religious ones are difficult to talk about, but they can’t be ignored because they influence behavior”. This ties back to the reading because when we talk about “Defining the system” this is reality and like Molly touched on you can not ignore the problems and that is where having a system in place and steps to take are a necessity in today’s time. Cultural Eutrophication is an issue that has been going on for years in geological times and it affects our lakes and rivers because we have animals that live in those areas and the human population pollutes that from having human water going into sewage and speeding up the aging process and hurting our ecosystems. Cause is complex, but making it known is just as important because it is key to help find solutions to world problems. This leads to having a causal chain analysis which starts off with an indirect driver then a direct driver and then the effect. This usually can be broken down step by step and then able to retrace your steps back to the root cause. In the chapter it gives an example of a cause-effect  relationship when you get a stomach ache after eating cereal and the milk smells sour. You have now established a cause effect relationship scenario.  Correlation =/ Causation and this basically means that you can have a problem arise in a situation but it doesn’t mean that’s the main cause of the situation, it could be multiple reasons or drivers.
