The nu-scheme should not be taken all too literal, it only concerns itself with recent changing voices when it comes to pristine ecosystems. Some of these voices are from and associated with ecomodernism, but not all new environmentalists are ecomodernists. E. O. Wilson is an opponent of the new environmentalists, he values original and pristine ecosystems, and was heavily critical of Emma Marris. But, he might well be an ecomodernist in disguise as he, like the ecomodernists, think we need more intensification of agriculture and more development so that we can set a-side half of the world as this allows uncoupling of natural areas.
I can agree with development being good, if it were done more responsibly and we werent'so immensily wasteful. Haven't read Rachel Carson, know who she is and what she wrote about, but her book hasn't stopped increasing intensification and with it loss of life in the rural countryside. There are alarming rapports about the decrease of invertebrates (insects and other bugs).
I come from the Netherlands, and that has given me different experiences and shaped my views differently. Figures like Leopold and Thoreau are hardly relevant here, because there's no wilderness left. To get back to agriculture, at least the EU has more stricter rules as the United States has.
Elizabeth Kolbert. Know the book haven't read it, am aware of the loss of biodiversity, and have sort of going to the stages of grief and towards acceptance. I don't feel I can stop it from happening, and I take comfort in the novel ecosystems.
In most ways I am your typical environmentalist; I'm anti-consumerist, skeptical of capitalism (but I see no realistic alternatives), eat mostly vegan, think the private car was a mistake, and so on.
Where I differ is that I disagree that pristine nature, wilderness, is more valuable as emerging ecosystems - with the exception of monocultures, which I think we can all agree are bad. In the Netherlands ecologists want to recreate the prehistoric nature by putting cattle and wisents behind fences. They have some theory behind it, but I have a feeling they cherry-pick to justify their rewilding visions. I consider them reactionary and see their love for the past as a kind of fetish - harsh but that's how I see it.
One of the most influential works were from an artist Christ Jordan. I suggest to check out his project "Running the numbers". There is not that much wrong with technological development, but the way we are wasting resources, cheap fossil fuels and destroying the soil we depend on, is highly repulsive.
Perhaps we have luck on our side, and the problems affecting us will be solved, but I think there is a high chance future generations will look at our generation with some disgust.
