Tom T. Hall's song "One Hundred Children" is about the importance of preserving the world for future generations. The song features one hundred brave boys and girls from different nations who come together to march and sing a song about their hopes for the future. The children's message is clear - they plead with the adults not to blow up the world, not to kill all the flowers, and to leave something behind for them. They ask for pure water, uncut forests, and a world that is free from destruction and chaos. The song also touches on the role of religion in society. The children acknowledge that there are many different beliefs in the world, but they believe that their God is still alive and that they cannot survive without Him. They urge people to punish the bad and praise the good, and to talk about brotherhood with their neighbours. At the end of the song, the singer reflects on his own thoughts about right and wrong, and how the marchers have now become one hundred and one. The message is that, no matter how small or insignificant their actions may seem, coming together and taking a stand can make a difference in the world. Overall, "One Hundred Children" is a powerful reminder that the responsibility of protecting the planet for future generations rests in our hands, and that we must all work together to ensure a better tomorrow for all.
