It’s interesting to imagine what the planet might be like after humanity. This picture assumes we have failed to control the climate, sea levels have risen and rainfall increased. Places that are now solid dry land will flood frequently and bridges will often be destroyed. The picture shows a fish eagle – currently an African bird, returning with its lunch past the remnants of a stone road bridge in England. In the background is a thriving forest. It all looks rather pretty. I guess humanity needs to decide whether it wants to be part of a great green future, or not.
