點先可以reduce the emission of Green House gases20分!!!!!!!

Some ideas for reducing the emission of greenhouse gases:

1. Use renewable energy and reduce use of fossil fuel
eg: Use more solar energy, hydroelectric power, hyberid automobiles

2. Reduce the amount of smog forming particles and reduce the strain on the ozone
eg: use lesser CFC

3. Improve building design to use more natural lights instead of articificial lights

4. Use energy efficient products

5. Plant more trees

6. Promote the correct environmental eduction to the public (eg: in the school)
eg: Change the consumers ideology towards the environment

Ways of reducing the emission of greenhouse gases:

1. Waste recycling
The emission of greenhouse gases can be reduced by producing less waste.

2. Use public transport
Less carbon dioxide (one of the greenhouse gases) is emmitted by using less fossil fuels.

3. Avoid using sprays
Stop the use of products that release of CFCs (Chlorofluorocarbons, one of the greenhouse gases).

4. Plant more trees
Trees can absorb carbon dioxide and release oxygen. They can help to create a cleaner environment.


Besides, international cooperation, such as the Kyoto Protocol, is also needed.
