Ozone layer protects the humans. It declines the entrance of UV rays.
We have to protect the ozone layer to allow human existence. This existence of ozone is the reason behind human survival.
the use of CFC's hurt ozone. It depletes the layer.
Ozone layer is consisted in the stratosphere layer. This layer is very protective for human population.
Some gaseous products of human activity can reduce the about of ozone in the upper atmosphere, thus decreasing the effectiveness of the ozone layer in shielding the surface of the planet from ultraviolet radiation.
Ozone layer must be protected to allow human survival. Motivation regarding human survival is enough for this.
The formation of depletion layer of ozone is due to human made ODS. They react with the ozone layer and then deplete it.
The release of CFC's lead to ozone layer depletion. It reacts with ozone to deplete it.
The ozone layer is of value to human as it guards mankind against exposure to the harmful ultraviolet radiation coming from sun.
Humans create CFCs which are ozone depleting substances. They react with ozone present in ozone layer and deplete it.
The ozone layer is something very precious for the human race. But this human layer is being destroyed by the reckless use of the harmful CFC's by man thus making a kind of ozone hole in the ozone layer. This ozone layer cannot be replenished by man made sources. This is because the amount of ozone which is prepared by man is very negligible as compared to the amount which is depleted.So the ozone can only be replenished if the amount of CFC's which are consumed by the human race is decreased.
All of the problems in ozone are due to human activity. This has even caused a hole in ozone.
Humans are affected by the ozone layer. If there was no ozone, there would be no human life.
