Are there signs that serve the public good about real dangers that are not apparent? These are signs that warn of less visible present and future threats. Most think of the rainforest as the lungs of the planet. However, it is Algae that gives us the most oxygen. The use of chemical fertilizers for lawns flows from lakes to rivers and pollutes these precious Algae, the actual lungs of our planet. Breath deep and enjoy your symbiotic relationships, as each word you speak has the breath of Algae, so they give us a voice.
