"The challenges facing our society at the moment effectively are the unintended consequence of a solution we found in the late 1700s when society was running out of energy, we had no more timber, and we realized we could dig underground for ancient fossilized woodland, which is basically what coal is from about 300 million years ago. The consequence of burning all that coal and then oil was a release of carbon dioxide, changing our atmosphere and warming the planet. So, it's a problem born out of our ingenuity and resourcefulness, but I'm confident that we will find the solution out of our ingenuity and resourcefulness."
