From the Dawn of time until now, a single thread unites all life that has ever existed or currently does exist on this earth.  We are all interconnected and the actions of each of us do affect the whole.  Although we may not see the immediate connection of our actions or inactions, the thoughts, feelings, and energies permeate and penetrate through the space time dimensions.  All of our hopes and aspirations are linked closely with each other - although we may not comprehend it immediately.
