As far as we know the greenhouse phenomenon is getting worse day by day. And many greenhouse gases occur naturally, such as water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Meanwhile manmade greenhouse gases happen such as hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and sulfur hexafluoride (SF6) result exclusively from human industrial processes.
The main contributions of greenhouse phenomenon are human activities which are:
1. Burning natural gas, oil and coal.
2. Farming activities and land clearing.
3. Industrial gases discharge from factories.
4. Deforestation.
5. Increased in population growth.
With all the human activities mention above, it will only bring more and more damages to the earth. In the end, our next generation won’t be able to enjoy the clean air mother nature can offer, and also clean and healthy environment.
