He deeply loves the landscape that has been intensively managed by people since time out of mind and that he has watched over the course of his life being destroyed by mechanised agriculture. Now, what's left is being obliterated by hundreds of thousands of acres of crops to produce biofuels, and the views are being ruined by gigantic windmills.
Lovelock blames this destruction on "urban imperialist infiltrators" who know nothing of the beauties of plants and animals or the pleasures of country life and who have been duped by the Greens into thinking that the worst things imaginable are trace pesticides in their food, or electricity provided by politically incorrect sources. As a countryman who is passionate about the country and who sees citification as the greatest threat to what is best in being human, Lovelock draws on a much deeper stream of Western culture than is present in his Gaia theory. He partakes of the tradition represented by Henry Williamson and J. R. R. Tolkien in England in the 20th century and by Coleridge and Wordsworth in the 19th.
I should note that I've always liked the Gaia theory. In fact, one of my favorite notions is that a divine being might very well appear to us, from our point of view, as an immensely distant and huge sphere of continuously exploding gases.
