Michael Shermer, a renowned author and Presidential Fellow at Chapman University gave valuable comments to one of the most disturbing questions regarding the significance and meaning of our life: do we and our actions matter in the universe? The question seems valid. Compared to cosmic scales (to the Milky Way, let alone to the observable universe), not just we, humans, but Earth itself is insignificant, less than a grain of sand on the seashore. We are so proud of our achievements, but we can hardly leave our own planet. We say that we rule the Earth, but we are more like ants on its surface, more depending on nature than ruling it.
Michael Shermer, however, shows that our actions do matter, if we make the analysis at a proper level. We shall assess our actions at the human size and timescale, at where we actually are. Our actions do matter to our friends, enemies and also to our society. See the article below. We can add only one thought to this. If we are diligent, lucky and if we are very smart, making the right decisions, we may even reach a level of development and may live long enough to have some effect on systems beyond the Earth and the solar system. Our current actions do matter to our own future and potentials as well.
