The number one cause of climate change or global warming is us, humans. I believe that us HUMANS is the great cause of global warming because of becoming IRRESPONSIBLE. We become more greedy and forget about the negative effect that may cause by our wrong doings just like illegal logging, throwing our garbage anywhere, burning plastics and the waste that came from big companies. In our own simple way we can help saving our mother earth by not doing those things and spreading an awareness campaign on the negative effects of climate change through social media sites like facebook, twitter and etc.
