Chlorophyll makes our Earth green, healthy, and livable. In fact, the light-dependent reactions of photosynthesis would never occur without it! Thanks to this small, under-appreciated, yet magnificent ring, we can breathe! The answers to climate change and pollution lie within it, and so do cures for diabetes, various types of cancer, internal wounds, and Immune system disorders! Chlorin allows plants to get energy from the sun, so we have food to eat. This neat ring with a magnesium center is vital to our every day. So, let's be thankful that this exists, because if not neither would we!
