Global warming is caused by greenhouse gases such as carbon dioxide, CFCs, methane and HCFCs released from activities like deforestation, agriculture, and industrialization. This leads to extreme weather, rising sea levels as ice caps melt, ecosystem damage like coral bleaching and extinction, and problems like desertification and infectious diseases. Individual actions like using less energy, traveling efficiently, afforestation, and conserving resources can help address the climate crisis.

1. Global warming

2. Cause Greenhouse gases. For example, CO 2 , CFCs, H 2 O, Methane, HCFCs, etc.. Deforestation Slash-and-burn agriculture, Excessive pasturage, Acid rain, Commercial felling etc…

3. Effect Extreme weather Tropical Cyclone, Drought, El-Niño, La-Niña, Sea level rises Melting ice caps, Shore Erosion,

4. Effect Ecosystem Whitening of Coral, Extinction, Red Tide Destruction of ecosystem, Influence on fishery

5. Effect Desertification Aral Sea, Australia, Gobi, Sahara, Infectious disease Dengue-fever, Hantavirus Pulmonary Syndrome

6. Things we can Save electric energy Use public facilities for travel Take a bag when we go shopping Afforestation volunteer Set the air conditioner at 28℃ Save water Cool biz
