I hate the punking out on exploring, but I argue with my brother on space colonization, because I don't want us to have an out until we learn how to clean up after our messes on this planet. I hope we don't get the skills to just go mess up someone else's planet before we figure out how to live more environmentally friendly on this one. I'm not suggesting an either/or between funding the space program and the environment because the space program helps us come up with technology that aids environmental science, but it's all moot since the funding all goes to the military instead.
