This biodiversity is being lost destroying natural mechanisms that,could repair the damage caused by man.,Findings show that losing plants and animals is not only reducing our quality of life but actually,endangering our very existence. We cut down rich forests and replace them with one species plantations,,such as pine and eucalyptus. We plough up meadows rich in different grasses and herbs and replace them,with one grass, for instance rye or wheat.,When a natural ecosystem is simplified the basic processes in the eco-system are altered and even,damaged. Without their biodiversity they are not able to serve as the natural cleaners of our planet. No,longer are they able to absorb the carbon dioxide that is being produced in excess.
