I've always felt that if you want to galvanize change in the world, if you really want to understand how it can be done, you start by demonstrating how something already works.  You have to figure out some sort of inflection point and be able to articulate the energy and outcomes in a system.  

How great it is that you are interested in art, or tools, fishing, or rockets; this is how the world goes around, each of us deliberately and passionately involved with something of our own.

Much of the present environmental and political news has a common theme where it's difficult for anyone to even agree on the facts.  True, the mysteries in the world are so complex that as laypeople, we can't be expected to know everything, we must accept some form of consensus among stakeholders – bearing in mind that stakeholders will instinctively try to emphasize data that supports the value of their beliefs, and avoid simple data and key outcomes that could suggest there are things that need to be addressed or retooled.  Pay attention to what outcomes we are instrumenting for, and be introspective and intent about what we know we can do to improve.  When we approach problems with an open mind, a solution can sometimes appear effortlessly.
