Ozone depletion Man-made compounds such as chlorofluorocarbons (CFCs), hydrofluorocarbons (HCFCs) and halons destroy ozone in the upper atmosphere (stratosphere). ... Stratospheric ozone loss can result in potential harm to human health and the environment, including: increased incidence of skin cancer and cataracts.

How does ozone affect animals?
Ozone appears to be a weak mutagen and to produce chromosomal abnormalities. Defects in defense against airborne infection are present in animals, which are more susceptible to airborne infection after ozone exposure.
How are CFCs harmful for the environment and living beings?
a) CFCs are harmful to environment and living beings because. .. it increases greenhouse gases in the environment which results in forming holes in the ozone layer.. And if this happens it will cause to an increase in the UV rays exposer, and which will make the earth's surface much more heater than before.
How are animals affected by ozone depletion?
Scientists have demonstrated a direct reduction in phytoplankton production due to ozone depletion-related increases in UVB. UVB radiation has been found to cause damage to early developmental stages of fish, shrimp, crab, amphibians, and other marine animals.
Is ozone layer harmful for humans and animals?
Correct statement: The ozone layer is not harmful to humans and animals.
Why is ozone bad for dogs?
Ozone air purifiers use a process called oxidation to remove mold, bacteria and other pollutants from the air. ... Ozone unfortunately is a toxic substance and should never be used around pets or humans.
How does the ozone layer protect animals?
The ozone layer acts as a shield for life on Earth. Ozone is good at trapping a type of radiation called ultraviolet radiation, or UV light, which can penetrate organisms' protective layers, like skin, damaging DNA molecules in plants and animals.
How are CFCs harmful to human beings?
CFCs contribute to the loss of the protective ozone layer, which blocks ultraviolet rays from the sun. This exposes more people to UV radiation, which can cause skin cancer. According to the University of Georgia, one in five Americans develops skin cancer in his or her lifetime.
How do CFCs destroy ozone?
Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules. ... When sunlight returns in the spring, the chlorine begins to destroy ozone.
Why CFCs are considered as pollutants?
The chlorofluorocarbons release chlorine atoms when they break down in the presence of UV radiations and thus deplete the ozone layer. The chlorine released reacts with ozone molecules and forms oxygen which reduces the ozone quantity causing its depletion. This is the reason why CFCs are considered as pollutants.
How does UV light affect animals?
more direct entry of ultraviolet (UV) radiation to the Earth's surface. ... Livestock species are particularly vulnerable since excess exposure to solar radiation can cause skin lesions, optic tumors, caloric stress or even death, with substantial consequent financial losses in the industry(3).
What are 2 effects of the ozone thinning on animals and plants?
There is concern that ozone depletion may lead to a loss of plant species and reduce the global food supply. Plants form the basis of the land food web, prevent soil erosion and water loss and are the producers of oxygen. Scientists have shown that over 100 species of plants may be sensitive to ozone depletion.
How is ozone layer important to plants and animals on Earth?
the ozone layer is too important for plants and animals because it's helps to stop the sun most harmful UV rays which fall on the earth. These UV rays can causes to many types of disease which fall is very dangerous for all living organisms like cancer etc.
What are the major effects of ozone layer on humans plants and animals?
Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
How does ozone depletion cause harm to organisms?
Stratospheric ozone depletion leads to an increase in UV -B that reach the earth's surface, where it can disrupt biological processes and damage a number of materials. ... Scientists also indicate that increased exposure to UV -B rays affects the human immune system and causes premature aging of the skin.
