It’s a very big question. I think it is one of those things like many changes that happen on a societal scale or a community scale or a local scale or an international scale, change happens in such small ways and sometimes we don’t notice the individual change happening until someone stops and says well look at the cumulative effect of everything we have done over the last few years. Of course with climate change there is a huge amount of acceleration in the post-industrial era so there is an awful lot of people in the past doing what they thought was the right thing for the economy, doing what they thought was the right thing for people in their countries without actually understanding the science of what they were doing at the time. Thankfully as our understanding grows and as the science moves on we all can start making different decisions.
