2.  Greenhouse gas is a gas in an earth’s atmosphere that consumes and give offs the radiation.  The green house gases cause the greenhouse effect that make earth’s surface hot.

3.  Carbon dioxide (CO2): carbon dioxide take over 50% of greenhouse gases. And past 50 years, CO2 has been increasing at 0.25%.  Methane (CH4) : methane is common gas that humans or animals produce.  CFC: CFC which is chlorofluorocarbon is one of the organic greenhouse gases.

4.  As I said before CO2 take over 50% of greenhouse gases.  This gas is usually formed when you burn the fossil fuels or breathing or when volcanoes erupt.

5.  Brings the greenhouse effect  Makes acid rains: carbon dioxides can melt to the water, so when the water evaporates and changes to the cloud that contains rain, the acid rain happen.  Result of acid rain:

6.  Greenhouse gases can bring greenhouse effects. If greenhouse effect happens moderately, it would cause good effects, but if it happens overwhelmingly, it can cause the temperature increases.

7.  There are approximately 700,000,000 people in this world and 20% of people are farmers, but the greenhouse effects continues, many plants will die, so people will not choose to be a farmer. And that will bring inflation of food price.

8.  Scientists tried many things to solve the greenhouse gas problem. Some tries had been funny. In Russia, scientists used nuclear bomb to burn the trashes. But of course it failed, and got worse because not only CO2 was made the radiation was made too.

9.  There is a part called refrigerant in the air conditioner, and that parts emits carbon dioxide. So some company stopped to use refrigerant and use another material. So air conditioners that are used in present days emits only 4% of CO2 than before.

10.  Here are some ideas to make less greenhouse gases.  Walk if the place you are trying to go is near enough: if you walk, you are not only making less greenhouse gases, it makes you healthy  Use public transportations if it’s far from your house: public transportation does emits gas but it emits less gas than every single person use their own car

11.  Plant more trees: trees consumes CO2 and emits oxygen. And CO2 is over 50% of all greenhouse gases. (I think this is the best solution)  And finally, use less electronic devices.
