Introduction




Other planets have sunlight, but the Earth is the only planet we know that has air and water. A diverse community of plant and animal life has thrived on this planet for millions of years, sustained by the sun and supported by the soil, water and air. Air is a precious resource that most of us take for granted. Air supplies us with oxygen and supports our respiratory system which is essential for our bodies to live. Without air, we would be unable to sustain life and absolutely die within minutes.
