The world needs a new source of energy, an unspillable source.

Does/Should Christains concern themselves with worldly conflicts? (ozone, tree cutting, 9/11 conspiracy, etc)?

So many things going on in our world that can make a persons head spin. Should we spend time or focus our energy with items such as the 9/11 conspiracy, saving the trees/whales/etc, boycotting companies for supporting non-christian groups, or any other type of issue that has nothing to do with our own personal salvation?
