Temporary increases in acidity also affect insects and other invertebrates, such as snails and crayfish, on which the fish feed.
Laboratory and epidemiological studies demonstrate that UVB causes non-melanoma skin cancer and plays a major role in malignant melanoma development. EPA uses the Atmospheric and Health Effects Framework model to estimate the health benefits of stronger ozone layer protection under the Montreal Protocol.
Effects on Plants UVB radiation affects the physiological and developmental processes of plants. Despite mechanisms to reduce or repair these effects and an ability to adapt to increased levels of UVB, plant growth can be directly affected by UVB radiation.
Indirect changes caused by UVB such as changes in plant form, how nutrients are distributed within the plant, timing of developmental phases and secondary metabolism may be equally or sometimes more important than damaging effects of UVB.
These changes can have important implications for plant competitive balance, herbivory, plant diseases, and biogeochemical cycles. Effects on Marine Ecosystems Phytoplankton form the foundation of aquatic food webs.
Phytoplankton productivity is limited to the euphotic zone, the upper layer of the water column in which there is sufficient sunlight to support net productivity. Exposure to solar UVB radiation has been shown to affect both orientation and motility in phytoplankton, resulting in reduced survival rates for these organisms.
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. The most severe effects are decreased reproductive capacity and impaired larval development.
Small increases in UVB exposure could result in population reductions for small marine organisms with implications for the whole marine food chain. Effects on Biogeochemical Cycles Increases in UVB radiation could affect terrestrial and aquatic biogeochemical cycles, thus altering both sources and sinks of greenhouse and chemically important trace gases e.
These potential changes would contribute to biosphere-atmosphere feedbacks that mitigate or amplify the atmospheric concentrations of these gases. Effects on Materials Synthetic polymers, naturally occurring biopolymers, as well as some other materials of commercial interest are adversely affected by UVB radiation.
Yet, increases in UVB levels will accelerate their breakdown, limiting the length of time for which they are useful outdoors.

The effects of ozone layer depletion are as follows: What are the effects of acid rain and ozone layer depletion on the earth? What is the motion for the greenhouse effect and ozone layer depletion?

Ozone Depletion In the Troposphere, Ozone is dangerous. Ozone forms in the atmosphere by the action of sunlight on oxygen.
Ozone higher up in the atmosphere protects life on Earth.
Ozone lower in the atmosphere (troposphere) can be toxic and a pollutant. ozone layer. Acid rain greenhouse effect 12, views. Share; Like; Download Ashrith N Shetty. Follow Published on Sep 2 Acid rain, ozone depletion, Global warming Nirwair Bajwa.
