I was really surprised to come across these words of Mrs Thatcher:
“We must remember our duty to Nature before it is too late. That duty is constant. It is never completed. It lives on as we breathe. It endures as we eat and sleep, work and rest, as we are born and as we pass away. The duty to Nature will remain long after our own endeavors…It will weigh on our shoulders for as long as we wish to dwell on a living and thriving planet, and hand it on to our children and theirs.”
These words were part of a speech made in 1990, less than a month before she ceased to be PM, at the 2nd World Climate Conference and the full text of the speech is worth looking at.
For a commentary on the current state of play on climate change have a look at this video on YouTube.
