Must of the Secondary Greenhouse Gases as of a result of human activities on earth ,such as gas flaring , àgricultural activities , deforestation , combustion from cars , industries etc. This brings about Climate change and global warming problems as a result of the greenhouse effects .                      

Most of the environmental activists would not even go in details telling people the causes of climate change during their advocacies . People need to be told what are the Major things in the atmosphere that are causing the climate change or global warming . Although must of the environmental activists are not even environmentalists by profession , they just dabble into the advocacy trying their own best .
