Here is what i know:
One of the most important measures of the health of the stream is the level of dissolved oxygen (DO) in the water.
Oxygen (O2) dissolves in water through the mixing of the water surface with the atmosphere.
The oxygen is used by fish and other animals in the water to "breath" through their gills or other respiratory systems and by plants. If the levels fall too low, many species of fish, macroinvertebrates, and plants cannot survive. At very low levels of oxygen, the stream becomes "septic" and smells rotten because low oxygen sulfur bacteria begin to dominate.
If the level of ozone is below certain concentration, then it is ozone depleted. It is called as ozone hole.
The ozone is depleted but not yet dead. It is depleted at some places.
Ozone layer is being depleted by CFC's. They react with ozone and decompose it.
The ozone layer is being depleted due to the continues usage to ozone depleting substances that is ODS. These ODS contain CFC which react with ozone present in the ozone layer and deplete it.
The ozone layer is getting depleted because of the continues usage of CFCs. These are the chemicals which destroy ozone by reacting with and decomposing it into molecular oxygen and nascent oxygen.
Ozone is being depleted by CFC's. They react with ozone and deplete it.
If the level of ozone is below certain concentration, then it is ozone depleted. It is called as ozone hole.
The ozone is depleted but not yet dead. It is depleted at some places.
The ozone depletion requires low temperatures. It is because ozone is depleted in Antarctica.
Ozone layer is being depleted by CFC's. They react with ozone and decompose it.
Ozone layer is a layer of earth. It is being depleted. The reason is CFC.
Dangers of depleted ozone are many. Cataract, immune system breakdown etc.
The ozone layer is being depleted due to the continues usage to ozone depleting substances that is ODS. These ODS contain CFC which react with ozone present in the ozone layer and deplete it.
The ozone layer gets depleted where temperature is cool. It is because of the property of ozone.
If the ozone in the ozone layer is depleted then, more UV will enter the earth. This will cause damage to life on earth.
If the ozone in the ozone layer is depleted then, more UV will enter the earth. This will cause damage to life on earth.
Some consequences of ozone being depleted are. Floods, global warming etc.
