I don’t really need a quick flick through the rolling news bulletins or my Twitter feed to remind me there are a lot of problems in the world. Conflict here, political repression there. Continuing poverty and economic hardship in poor countries, and the increasing gap between rich and poor. Environmental disasters around the globe, as ‘freak’ weather becomes the new norm in an age of climate change. Natural disasters, such as the recently reported loss of 400 million birds over the last 30 years.
