Sloths actually are like furry living ecosystems all by themselves! Algae grows on their fur and they are also home to "sloth moths" who call them home and drink their tears.
There is no waste in functioning natural ecosystems. All organisms, dead or alive, are potential sources of food for other organisms. A caterpillar eats a leaf; a robin eats the caterpillar; a hawk eats the robin. When the plant, caterpillar, robin, and hawk die, they are in turn consumed by decomposers.
Anyplace of work where you have a cross section of work, you have mini-ecosystem. A little representation of what the planet is. You have the Alpha Dog. You have the young ones, the old ones. The pissed off one. The quiet one.
Families are ecosystems. Each life grows in response to the lives around it
Ecology is often confused with environmentalism, while in fact, environmentalism often leaves out the fact that people, too, can be a legitimate part of an ecosystem.
We don't think a sustainable society need be stagnant, boring, uniform, or rigid. It need not be, and probably could not be, centrally controlled or authoritarian. It could be a world that has the time, the resources, and the will to correct its mistakes, to innovate, to preserve the fertility of its planetary ecosystems. It could focus on mindfully increasing quality of life rather than on mindlessly expanding material consumption and the physical capital stock.
Turn off your televisions. Ignore the Newt-Mitt-Rick- Barack reality show. It is as relevant to your life as the gossip on “Jersey Shore.” The real debate, the debate raised by the Occupy movement about inequality, corporate malfeasance, the destruction of the ecosystem, and the security and surveillance state, is the only debate that matters.
Now is not the time to repudiate environmental balance, but rather it is the time for all of us to work together - politician, advocate, rancher, scientist, and citizen. Only by doing this will the United States move forward and be a leader in environmental issues and ensure sustainability to our delicate ecosystem.
People need to know that they have all the tools within themselves. Self-awareness, which means awareness of the body, awareness of their mental space, awareness of their relationships - not only with each other, but with life and the ecosystem.
If we do nothing, we still get to a post-carbon future, but it will be bleak. However, if we plan the transition, we can have a world that supports robust communities of healthy, creative people and ecosystems with millions of other species.
I pledge allegiance to the soil of Turtle Island, and to the beings who thereon dwell one ecosystem in diversity under the sun With joyful interpenetratio n for all.
If enough species are extinguished, will the ecosystems collapse, and will the extinction of most other species follow soon afterward? The only answer anyone can give is: possibly. By the time we find out, however, it might be too late. One planet, one experiment.
Young entrepreneurs will make a difference in the Indian ecosystem.
It's a flaw in our argument, for sure. By any reading of evolutionary theory, creationists ought to have died out ages ago. They serve no function in the planet's ecosystem, and no other species has survived so long while in such fundamental disagreement with observable reality. If I wasn't such an ardent believer in secular materialism, I'd wager this is really troubling Darwin in the afterlife.
People like the robber barons assumed that the doctrine of the survival of the fittest authenticated them as deserving power. You know, "I'm the richest. Therefore, I'm the best. God's in his heaven, etc." And that reaction of the robber barons was so irritating to people that it made it unfashionable to think of an economy as an ecosystem. But the truth is that it is a lot like an ecosystem. And you get many of the same results.
While ants exist in just the right numbers for the rest of the living world, humans have become too numerous. If we were to vanish today, the land environment would return to the fertile balance that existed before the human population explosion. Only a dozen or so species, among which are the crab louse and a mite that lives in the oil glands of our foreheads, depend on us entirely. But if ants were to disappear, tens of thousands of other plants and animal species would perish also, simplifying and weakening land ecosystems almost everywhere.
I believe citizens are beginning to realize that their birthright, a healthy ecosystem, has been stolen, and they want it back.
An ecosystem that has the maximum amount of diversity is the richest.
What's sad is that nobody knows the constitution of the ecosystem that has just been destroyed. Is it an important future food? Is it an important medicine? What can it do for future generations - or present generations?
We are clearcutting virgin forests around the world, and 95 percent of species in the clearcut zone have never been studied. So we clearcut a part of the virgin forest and now part of our ecosystem has been wiped out. Some of it may grow back, and some of it won't.
We should not be living in human communities that enclose tiny preserved ecosystems within them. Human communities should be maintained in small population enclaves within linked wilderness ecosystems. No human community should be larger than 20,000 people and separated from other communities by wilderness areas. Communication systems can link the communities.
The "developed" nations had given to the "free market" the status of a god, and were sacrificing to it their farmers, farmlands, and communities, their forests, wetlands, and prairies, their ecosystems and watersheds. They had accepted universal pollution and global warming as normal costs of doing business.
As species are exterminated by shifting climate zones, ecosystems can collapse, destroying more species.
The nuclear peril is usually seen in isolation from the threats to other forms of life and their ecosystems, but in fact it should be seen at the very center of the ecological crisis, as the cloud-covered Everest of which the more immediate, visible kinds of harm to the environment are the mere foothills.
I stand by my assertions that although you can know what happens to any individual species that you modify, you cannot be certain what will happen to the ecosystem. Also, we have a strange situation where we have malnourished fat people. It's not that we need more food. It's that we need to manage our food system better.
