“It is ordinary human habitation and use (farming, forestry, hunting) of land which does most ecological damage.”
That includes energy farming as well, wether biofuels, biomass, or wind and solar. The latter aren't quite as bad as feeding crops and pelletized forests to the flames, but wind and solar are still extremely diffuse, and the collection hardware has a large ecological footprint. Not only the vast swaths of land permanently occupied, but the access roads and transmission lines. Moreover, wind and solar are both highly resource and energy intensive to manufacture, and that energy comes from coal. It is an extremely inefficient use of our resources for very small, if any benefit.
Energy density matters, as do modern farming techniques which allow more food to be produced on less land. We should be focusing on concentrating our activities in the smallest possible area, not "harmonizing" with nature by using expensive and ineffective technologies which were abandoned centuries ago. Ecomodernism shows us the way, while conventional "environmental" organizations demonstrate no regard for preserving ecosystems, and only a single-minded focus on anti-nuclear activism, which inevitably translates to burning more fossil fuels.
