I wrote 'Big Yellow Taxi' on my first trip to Hawaii. I took a taxi to the hotel and when I woke up the next morning, I threw back the curtains and saw these beautiful green mountains in the distance. Then, I looked down and there was a parking lot as far as the eye could see, and it broke my heart this blight on paradise. That's when I sat down and wrote the song.

It was cold and windy, scarcely the day to take a walk on that long beach Everything was withdrawn as far as possible, indrawn: the tide far out, the ocean shrunken, seabirds in ones or twos. The rackety, icy, offshore wind numbed our faces on one side; disrupted the formation of a lone flight of Canada geese; and blew back the low, inaudible rollers in upright, steely mist.

The climate is nearing tipping points. Changes are beginning to appear and there is a potential for explosive changes, effects that would be irreversible, if we do not rapidly slow fossil-fuel emissions over the next few decades.

It is the marriage of the soul with nature that makes the intellect fruitful, and gives birth to imagination

The tropical rain forests are a telling example. Once cut down, they rarely recover. Rainfall drops, deserts spread, the climate warms.

I drive a hybrid, and we've changed our light bulbs and windows and installed solar panels and geothermal ground source heat pumps and most everything else.
