It is not my nature to express opinions of a political nature, but on Earth Day, I believe there are things to say that go beyond politics. So much that we take for granted, is threatened. Climate change is real and has been accelerating. We have entered a time period where biodiversity is severely threatened and species are disappearing at an alarming rate. World wildlife populations have been reduced by about 50% in the last 40 years. We are on the brink of the sixth mass extinction in the history of the planet. Are we taking notice? Political pronouncements of the last week have been encouraging. However, recent history has seen that similar announcements made in the past have not resulted in any significant change in behaviour. Will it be different this time?
