Safe water and air are essential for all life forms on earth and there are “safety limits” where water and air can turn unsafe, dangerous or even toxic. Healthy water is carrier of nutrients and healthy air is carrier of oxygen and carbon dioxide (with specific composition), both of which are required for healthy life. Healthy water and healthy air are, also, fresh and free from toxic matter “clean”, under such conditions all forms of life are healthy.
Fresh water, fresh air and healthy eco-systems are related in complex web of functioning, interactions and metabolism. Nature managed to great extent to “clean” itself, to optimize and fix all life parameters in an extremely accurate and delicate balance. Evolution of life on earth struggled for millions of years to bring about perfect living environments and climate conditions. As a reslut of such long struggle earth provided humans with healthy food. What didn’t happen over-night we succeeded to change over-night. We are competing more and more to degrade the life quality on the earth and we are succeeding.
The water and air we are polluting are the raw material and the natural resources for our life. If we ignore them and don’t take care of them, i.e. make them fresh, they wouldn’t care about us and they will ignore us. If we turn them to victims, they will also turn us to victims!
