people and governments are stupid, you can't just protest about something as ambiguous as "climate change" how would that be addressed if they even wanted to take a tiny bit of notice?
thousands of people protested about going to war in Iraq and they didn't listen one bit, do you think this has a better chance?
At least try to identify the key contributors to this "climate change" and address them, ie: protest about vehicular emissions in cities, or consumer packaging, or procreating humans, etc...the list goes on.
