Question

write any two consequences if the ozone layer gets depleted completely

Answer 1

1.Ultraviolet rays will reach the earth and affect human beings.......

Answer 2

Dear user...



✔✔Impact on Humans

Skin cancer: Exposure to ultraviolet rays poses an increased risk of developing several types of skin cancers, including malignant melanoma, and basal and squamous cell carcinoma.
Eye damage: Direct exposure to UV radiations can result in photokeratitis (snow blindness), and cataracts.

Immune system damage:Effects of UV rays include impairment of the immune system. Increased exposure to UV rays weakens the response of the immune system.
Accelerated aging of skin:Constant exposure to UV radiation can cause photo allergy, which results in the outbreak of rashes in fair-skinned people.
Other effects: Ozone chemicals can cause difficulty in breathing, chest pain, throat irritation, and hamper lung functioning.

✔✔Effects on Amphibians

Ozone depletion is listed as one of the causes for the declining numbers of amphibian species. Ozone depletion affects many species at every stage of their life cycle. Some of the effects are mentioned below.Hampers growth and development in larvaeChanges behavior and habitsCauses deformities in some speciesDecreases immunity. Some species have become more vulnerable to diseases and deathRetinal damage and blindness in some species

✔✔Effects on Marine Ecosystems

Plankton (phytoplankton and bacterioplankton) are threatened by increased UV radiation. Marine phytoplankton play a fundamental role in both the food chain as well as the oceanic carbon cycle. It plays an important role in converting atmospheric carbon dioxide into oxygen. Ultraviolet rays can influence the survival rates of these microscopic organisms, by affecting their orientation and mobility. This eventually disturbs and affects the entire ecosystem.

✔✔Impact on Plants

In some species of plants, UV radiation can alter the time of flowering, as well as the number of flowers produced by a plant.Plant growth can be directly affected by UV-B radiation. Despite mechanisms to reduce or repair these effects, physiological and developmental processes of plants are affected.



hope this helps
