Álvaro Correa Posted almost 2 years ago The colonization of Mars vs. solving the problems at home The more we know the easier we will find solving problems. It is well-known we have serious issues to investigate and to improve here at the Earth, but we researching into new things give us new knowledge to take advantage of. We might find that a living thing use a system whose cells are made in a way that they cannot suffer cancer... This is just an example. When spanish discovered America they started using some techniques that they did not know previously. They started cultivating cacao which everyone hankers after it now... We must keep spending money at this issue!
