Transcript of Ozone Layer Biology Form 4

COSMOS 1014 OZONE LAYER What is Ozone ? Importance of Ozone Depletion of
ozone layer Effects of global warming Impact of thinning of the ozone layer and global warming on the ecosystem Steps to reduce global warming => Melting of polar ice and glaciers causing a rise in sea level
=> Change in wind direction and weather patterns
=> Increase of droughts
=> Intense rain in some regions
=> Flood in low-lying countries ~ Reduce the burning of fossil fuels
~ Reduce deforestation
~ Reduce or stop open burning
~ Practice replanting of tree
~ Develop sources of energy Molecule that contains three oxygen atoms

Blue in colour and has strong odour

10 millions air molecule , 2 millions oxygen ,
3 ozone Acts as a shield to absorb the UV rays Causes : Increasing level of chlorofluorocarbon Sources : - Coolants in air conditioners and refrigerators
- Propellants in aerosol cans
- Solvents in electronics industry
- Foaming agents in the making of polysterene boxes Solutions : * Reduce or stop the use of CFCs
* Using HCFCs to replace CFCs
* Signing of montreal protocol Effects : ~ Skin cancer and melanoma
~ Eye damage such as cataract
~ Decrease in nutrient content and crop yields
~ Killing of phytoplanktons
~ Change in wind directions
~ Climatic changes # Sea water becomes warm due to global warming

# Ecosystem are slowly loosing its flora and fauna

# Ecosystem become unstable

# UV radiations affect the photosynthesis By :
