We should find cure for aging

ADAPTATION First it doesn't necessarily means that population will grow if we find aging cure. Yes, people will live longer, but it will affect their reproductive system. In nature there is a rule that the bigger child mortality - the more children family has. More quality life with less child mortality - the less children family has. So the people population is regulated by nature and there is nothing to worry about. Your whole "Harm to animals" argument is based on presumption that there will be a lot more people on the planet which is unlikely. The world is changing more rapidly than ever, in all areas. For pollution - people are aware of it and today all new cars have economic engines. http://en.wikipedia.org... Also electric cars are booming for last couple of years and very soon gasoline powered cars will be history. Thanks to Tesla motors :) http://www.teslamotors.com... Electric power, clean power, obtained from sun and wind are developing faster then ever http://www.solarcity.com... People are becoming more ethical, more civilized, more reasoned and there for even if population increases we will be able to sustain more people, development of clean, more efficient technology will contribute to that too. Not only that it"s not "fun" to be old and sick, old people don"t contribute, they spend a lot and are burden to humanity. Eliminating old age is not just a attractive desire, because of change of demand in work (changing careers and learning new skills) it"s crucial to find aging cure to save humanity. "The first obvious implication of a population that is getting a lot older without growing much is that, unless the retirement age changes, there will be fewer workers. That means less output, unless productivity rises to compensate." Only the rise of productivity can save us, which is finding aging cure. http://www.economist.com... Because of progress and change of work system, fight for job doesn"t make sense , we would have this problem only if there is constant amount of jobs, but more people = more jobs, because people create jobs. We are explorers by nature so we will never stop wanting, building, creating jobs. Jobs are changing in a way that people are working many jobs in their life, it's no longer one job for whole your life, so different times requires different people, jobs require people to be more adaptive, being able to constantly learning new skills, old people can't learn new skills. EXPANSION IN TIME AND SPACE If we want to expand in space we must expand in time too. Space exploration has made significant progress in last years too and space tourism is at the doorstep, the announcement for space tourism is coming from several companies like Space X http://www.spacex.com... http://mashable.com... If we want to reach distant planets we will need to live a lot longer. The new world has started already, this is just one part of the new world, it is the right thing, the natural part of evolution. We are not animals, our life has more value, we should fight for it, not let it be defeated by time, just like we"re not letting it be defeated by other causes such as injuries and diseases. This is no different than hygiene which prevents diseases, the only difference is that now, for the first time in history we have the technology and power to make it happen.
