earth’s natural cycles
If a city’s water and air were cut off, disease would soon follow, and yet our world gets no fresh water shipped in, nor our waste out. It stays clean through natural recycling systems. Water, carbon, oxygen, and nitrogen work together to keep the environment healthy and habitable for everyone.
The Water Cycle
Water continuously moves through our environment. Sun warmth turns liquid into vapour, which floats into the air and forms clouds. It then falls back to the ground as rain or snow, feeding rivers and oceans so people have fresh supplies.
The Carbon and Oxygen Systems
Living things need these essential gases to survive. Plants absorb carbon dioxide and release fresh oxygen, whilst people and animals breathe in that oxygen and exhale carbon dioxide. It’s a balanced, ongoing loop that doesn’t waste resources.
The Nitrogen Process
Nitrogen makes up nearly 78% of the atmosphere, but living creatures can’t use it straight from the air. Tiny soil organisms transform this element into a form that plants absorb through their roots. Animals then gain these nutrients by eating the plants, and when they die, microbes return the element back to the soil and air.
Through these ‘unseen‘ cycles throughout the world, nature continuously cleanses and restores itself so life can thrive!
