the wake of my recent considerations on the sixth great extinction is happening at the hands ours, it makes me reflect on the role of our species in the long history of life. Obviously, no organization was founded with an aim to make the universe, but it is inevitable that his life has an impact, in varying degrees, on other organisms. Various biological groups have indelibly marked the history of the earth: the cyanobacteria that altered the primordial atmosphere, making breathing for most of modern living groups, the first plants that made the land livable, arthropods that conquered and became part of each ecosystem, the dinosaurs, which were the dominant group of vertebrates for longer than any other. And then there is us, not as a group, but perhaps for the first time, as a single species, to cause an epochal event, the sixth great extinction. But our role should be only negative? Not necessarily. As I explained in the article, I think it unlikely that any major geological event or anthropogenic, however devastating, can erase all life, the only thing you can do is the total destruction of this planet, which will take place between 5 billion years when the Sun will end on fuel and we wrap you in an embrace of fire. Time there, but why not start now to provide for the highest goals, the escape from this world condemned flight that will make life that can expand from world to world and conquer the stars, effectively making them indestructible and filling the empty depths of the cosmos? Human science can certainly progress to be made possible the colonization of other planets, if not suffer a blow arrest because of the increasing stupidity of the population or of any mass mortality of which probably will be done if we continue to march on the route of 'extinction. 5 billion years is a long, our descendants may or totally different creatures, among the millions or billions of years, still widely in time to start thinking about the problem, but why not get busy in advance, why not be the first to take the biosphere into space and to make eternal life? The technology so far only a hypothesis of terraforming would be to make a livable planet unlivable, largely through the use of living things, made in the presence of the necessary resources to establish an ecosystem should be similar to Earth, making it habitable for humans. The road is certainly still very long, but definitely exciting, not only to expand the high ideal of life among the stars, but also in our own interest, such as growing population that needs space and resources.
