Breathe in, breathe out We're still alive because o2's throughout Air due to plants and algae Water, light, and a breath Is all it takes for plants to make Their food and the air that we breathe From lowly grass to lofty trees All plants on earth hold the key To all we eat, and all we breathe The source of all our energy Not all that we have On this earth is what meets the eye Because all that's green keeps us alive
