We can leave behind much more than just DNA. Through speech, music, literature, and movies... what we've seen, heard, felt... anger, joy, and sorrow... these are the things I will pass on. That's what I live for. We need to pass the torch, and let our children read our messy and sad history by its light. We have all the magic of the digital age to do that with. The human race will probably come to an end some time, and new species may rule over this planet. Earth may not be forever, but we still have the responsibility to leave what traces of life we can. Building the future and keeping the past alive are one and the same thing.
