I can understand space exploration without which, we would not have use of satellites which are so critical for modern communications. But I do not understand the need for colonization of another planet like Mars. Its atmosphere is mainly carbon dioxide, so can be broken down into oxygen and carbon, but is extremely energy intensive, but how is this practical if we are to build a colony there? Everyone wearing space suits?
