摘要：I have been intrigued by the Gaia hypothesis since reading Lovelock’s original
papers in the early 1970s. I read Lovelock’s first Gaia book in 1980, and over the years
my interest in Gaia has grown and deepened. I honor James Lovelock and Lynn
Margulis for fertilizing a vast field of productive speculation, observation, and
experiment – the Gaian research program. And I have always believed that the best way
to show respect to the founders of a field is to take their proposals seriously while
subjecting them to sustained critique. Here I will mainly focus on the ethical and
environmental prescriptions that are coming from those influenced by the Gaian
discourse and vision. But first I will give my brief take on the fundamental issue of
whether there is a Gaia theory which addresses the current status of scientific Gaia.
