The truth is, no we cannot change the past, we can only learn from the past to make the future better. In the future we will learn to take care of those most vulnerable, we will find cures to the many diseases including cancer and we will learn to live more sustainably and begin to clean up after ourselves and all this campaign is about is making us realise that we can make a real start right now, not years in the future and it will cost us very little.
