Copenhegan and Climate Change- neccessity or a mere hype

Its important for every citizen of this earth to understand what are the causes of Climate change, what are its repercussions, what are the simple way in day to day life...and our little effort, which can make the change for better or worsen the situation....as it can effect...we people, who live here including everything on the...earth. If citizens will be aware and industries will follow the norms...less fuel will be used,without harming devolopment....earth and we can be green and safe and sound....!!!!...I believe even poor but aware person can contribute for betterment...if they demand for kuddedaan...and if it is installed, they do not sell it off....then thing can be better....we all are hopeful!!!
