Greenhouse Gas Emissions

I searched on the Google and knew that The Kyoto Protocol, is an international treaty among industrialized nations that sets mandatory limits on greenhouse gas emissions. Greenhouse gas emissions, such as carbon dioxide (CO2), which can trap additional heat from the sun in the earth’s atmosphere, causing the ‘greenhouse effect’ and climate change. CO2 is the main greenhouse gas produced by motor vehicles. 

In my opinion, climate change is real, accelerating and caused by human activities. Example, Our personal vehicles are a major cause of global warming. People can help by driving less. If have to get out ,you can try to choose walk, bike, carpool or use public transportation instead of driving or taking taxi.
