Rockets into space poke holes in it. Aircraft cause it to thin. Combustion exhaust and cooling towers cause it to thin. Older refrigerants cause it to thin. Cutting down forests causes it to thin.
The layers of the Earth, such as the crust and mantle, influence human activities by affecting natural resources like minerals and fossil fuels. The Earth's layers also impact human safety by regulating events like earthquakes and volcanic eruptions. Additionally, the Earth's magnetic field, generated in part by the outer core, plays a role in navigation systems used by humans.
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.

We thinned it.
Ozone affect human as it forms a layer of ozone molecules in atmosphere. The molecules absorb the UV rays protecting the humans.
Ozone layer does not cause any adverse affect. It only allows the population to protect from the UV radiations.
Humans produce CFC's. These CFC's react with ozone to deplete it.
there are no layers of ozone. It is a single layer.
Ozone depletion potential refers to the potential at which the ozone is depleting. Human activities are the main reason for its depletion.
The release of CFC's lead to ozone layer depletion. It reacts with ozone to deplete it.
Humans burning fossil fuels are causing global warming. This is continuing unchecked and is causing climate change. Human production of CFCs (now stopped) was responsible for ozone depletion. The ozone layer is very slowly recovering.
ozone layers are low when they feel like it
