- The incredulous: Those who either know so little or haven’t had the opportunity to think about what they know, that they find the idea of collapse preposterous, unimaginable, and/or unthinkable.
- The hopeful: Those who believe that collapse is not inevitable or can be significantly mitigated, or believe that even if it is inevitable and can’t be significantly mitigated, we should try anyway.
- The deniers: Those who are intimidated or offended by, or overwhelmed with anger and/or guilt at, the very idea of collapse.
There are three (very large) groups to whom one cannot usefully or comfortably (or sometimes even safely) tell these truths:
I have always found that, when in a crowd that I know contains members of one or more of these groups, or whose members I don’t know well, it’s usually unwise to talk about what’s really going on in our world. For the first group it’s a conversation-stopper, for the second it’s either disappointing or annoying, and for the third it’s an invitation to a hostile debate or a fight, neither of which serves any purpose.

As I write this there are a dozen violet-green swallows flitting outside my window, soaring over my hilltop home and down into the valleys all around. Swallows are very adept at turning in mid-air, in a way that looks a bit clumsy but is actually ideally suited to catching insects in mid-air. They will also fly near larger birds in the hope of catching their moulting feathers in mid-air. The two pictures above depict this.
But I also know that swallows will perform these acrobatic feats, including catching and releasing feathers blowing in the wind over and over again, for no apparent reason. Just for fun. The fact that doing this is good practice for more serious pursuits is not the point — most wild creatures play as their principal means of learning new skills, but clearly take great pleasure in doing so for its own sake, just because it’s fun. [If you're a skeptic, look at this bird behaviour, or this one, and tell me this isn't pure, calculated, play].
Maybe the birds are telling us something. Their story, their way of coping with reality, is to play, to take joy in every moment. Maybe that is the story of all wild creatures: That life is play, delight, pleasure, laughter, living in Now Time. Maybe that should be our story, too, those of us who can no longer believe the invented stories of our culture, and who can no longer bear the story of grief and shame and anger and sadness and fear for our future that we have told ourselves about this terrible, real world.

"In the face of these realities, 21st century conservation is changing. Conservationists have taken steps to become more "people friendly" and to attend more seriously to working landscapes. Conservation will likely continue to create parks and wilderness areas, but that will be just one part of the field's larger goals. The bigger questions for 21st century conservation regard what we will do with the rest of it -- the working landscapes, the urban ecosystems, the fisheries and tree plantations, the vast swaths of agricultural monocultures, and the growing expanses of marginal agricultural lands and second growth forests that, as agriculture and forestry become more productive and intensive, are already returning to something that may not be wilderness, but is of conservation value, nonetheless.
In answering these questions, conservation cannot promise a return to pristine, prehuman landscapes. Humankind has already profoundly transformed the planet and will continue to do so.6 What conservation could promise instead is a new vision of a planet in which nature -- forests, wetlands, diverse species, and other ancient ecosystems -- exists amid a wide variety of modern, human landscapes. For this to happen, conservationists will have to jettison their idealized notions of nature, parks, and wilderness -- ideas that have never been supported by good conservation science -- and forge a more optimistic, human-friendly vision."

But ecologists and conservationists have grossly overstated the fragility of nature, frequently arguing that once an ecosystem is altered, it is gone forever. Some ecologists suggest that if a single species is lost, a whole ecosystem will be in danger of collapse, and that if too much biodiversity is lost, spaceship Earth will start to come apart. Everything, from the expansion of agriculture to rainforest destruction to changing waterways, has been painted as a threat to the delicate inner-workings of our planetary ecosystem.
The fragility trope dates back, at least, to Rachel Carson, who wrote plaintively in Silent Spring of the delicate web of life and warned that perturbing the intricate balance of nature could have disastrous consequences.22 Al Gore made a similar argument in his 1992 book, Earth in the Balance.23 And the 2005 Millennium Ecosystem Assessment warned darkly that, while the expansion of agriculture and other forms of development have been overwhelmingly positive for the world's poor, ecosystem degradation was simultaneously putting systems in jeopardy of collapse.24
The trouble for conservation is that the data simply do not support the idea of a fragile nature at risk of collapse. Ecologists now know that the disappearance of one species does not necessarily lead to the extinction of any others, much less all others in the same ecosystem. In many circumstances, the demise of formerly abundant species can be inconsequential to ecosystem function. The American chestnut, once a dominant tree in eastern North America, has been extinguished by a foreign disease, yet the forest ecosystem is surprisingly unaffected. The passenger pigeon, once so abundant that its flocks darkened the sky, went extinct, along with countless other species from the Steller's sea cow to the dodo, with no catastrophic or even measurable effects.

Conservation's binaries -- growth or nature, prosperity or biodiversity -- have marginalized it in a world that will soon add at least two billion more people. In the developing world, efforts to constrain growth and protect forests from agriculture are unfair, if not unethical, when directed at the 2.5 billion people who live on less than two dollars a day and the one billion who are chronically hungry. By pitting people against nature, conservationists actually create an atmosphere in which people see nature as the enemy. If people don't believe conservation is in their own best interests, then it will never be a societal priority. Conservation must demonstrate how the fates of nature and of people are deeply intertwined -- and then offer new strategies for promoting the health and prosperity of both.
"Here’s another round in what has become a heated, but ultimately productive, conversation on strategies for sustaining the planet’s biological integrity as humanity’s influence builds. Critics of Peter Kareiva, the lead scientist for the Nature Conservancy, had the floor in the last post and now Kareiva reacts:"
"In June 2010, a team of scientists and intrepid explorers stepped onto the shore of the lava lake boiling in the depths of Nyiragongo Crater, in the heart of the Great Lakes region of Africa."
What rational justification is there for conceiving of all living things as possessing inherent worth? In Respect for Nature, Paul Taylor draws on biology, moral philosophy, and environmental science to defend a biocentric environmental ethic in which all life has value. Without making claims for the moral rights of plants and animals, he offers a reasoned alternative to the prevailing anthropocentric view--that the natural environment and its wildlife are valued only as objects for human use or enjoyment. Respect for Nature provides both a full account of the biological conditions for life--human or otherwise--and a comprehensive view of the complex relationship between human beings and the whole of nature.
This classic book remains a valuable resource for philosophers, biologists, and environmentalists alike--along with all those who care about the future of life on Earth. A new foreword by Dale Jamieson looks at how the original 1986 edition of Respect for Nature has shaped the study of environmental ethics, and shows why the work remains relevant to debates today

Traditionally, analytic philosophers writing on aesthetics have given short shrift to nature. The last thirty years, however, have seen a steady growth of interest in this area. The essays and books now available cover central philosophical issues concerning the nature of the aesthetic and the existence of norms for aesthetic judgement. They also intersect with important issues in environmental philosophy. More recent contributions have opened up new topics, such as the relationship between natural sound and music, the beauty of animals, and the aesthetics of gardens. Using these materials, it is now easy to include a module on the aesthetics of nature as one part of an introductory course on aesthetics, or even to design an entire upper-level undergraduate or graduate seminar around the topic.
The reason such seemingly trivial mental tasks leave us depleted is that they exploit one of the crucial weak spots of the brain. A city is so overstuffed with stimuli that we need to constantly redirect our attention so that we aren't distracted by irrelevant things, like a flashing neon sign or the cellphone conversation of a nearby passenger on the bus. This sort of controlled perception -- we are telling the mind what to pay attention to -- takes energy and effort. The mind is like a powerful supercomputer, but the act of paying attention consumes much of its processing power.
Walking in a park in any season or even viewing pictures of nature helps improve memory and attention by 20 percent. All it takes is 30 minutes. Even when it's cold. Even when we don't enjoy it. The study by U of Michigan researchers found that effects of interacting with nature are similar to meditating.
Aldo Leopold is considered by many to have been the most influential conservation thinker of the 20th Century. Leopold's legacy spans the disciplines of forestry, wildlife management, conservation biology, sustainable agriculture, restoration ecology, pri
