Now the vultures are disappearing. Estimates suggest that 97 to 99 percent of the birds have gone in the last few decades. So the Parsi community is left in a very difficult position of trying to figure out how to appropriately and respectfully take care of their own dead in a world without vultures. It's estimated that they clean up five to ten million camel, cow, and buffalo carcasses a year in India. And that is obviously a free service. They've also played an important role in containing disease of various kinds and controlling the number of predators that feed on those carcasses and spread other diseases, like rats or dogs.
The worry now is that the decline in vultures may lead to rises in the numbers of scavengers and in the incidence of diseases like rabies and anthrax in India. You wrap the idea of the importance of mourning the loss of a species into a chapter about the Hawaiian crow. Do crows really grieve? Yes, I think there's very good evidence to suggest that crows and a number of other mammals grieve for their dead, and we don't quite know how to make sense of that.
In part this is bound up in those issues of human exceptionalism—the notion that grieving is something that only humans do. But it's clear from observations of different species around the world that crows do mourn for other crows. They notice their deaths, and those deaths impact on them. So the chapter is a provocation to us to pay attention to all of the extinctions that are going on around us, to take up the challenge of learning from them in a way that, I hope, leads us to live differently in the world.
That's right, thanks to really dedicated work by the Hawaiian state government, the U. They've been looking after these birds and breeding them in captivity for decades, and they now have over a hundred birds. But what they need is somewhere for them to be released. They need good forest, and there's not a lot of good forest left in Hawaii. Introduced species, like pigs and goats, have largely destroyed the understory of a lot of Hawaiian forest.
There are plans to fence some of these areas and remove the ungulates, so that the forest might be restored. It's a work in progress. But something a lot of people are dedicating a lot of time and energy towards achieving. Your book is also a clarion call to action.
You write, "We are called to account for nothing less than the entirety of life on the planet. That's a tough question, which I struggle with all of the time. It's one of the reasons that I write and tell stories. I love to do it. It's also something that I find challenging, and I think might contribute in some way.
So all that I can suggest to others is that they find ways of contributing, which they feel similarly passionate about and which might contribute, even in some small way. I don't think change comes from singular, world-changing events. I think it's built slowly, piece by piece, by people who are passionate about the world. Simon Worrall curates Book Talk.

Butterflies can fly long distances and feed on many types of flowers, but caterpillars are locavores, eating plants they hatch on or near. As those plants are lost to development or farming, butterflies disappear. Yet the island nation has lost 80 percent of its trees to development, charcoal production, and slash-and-burn agriculture. Lemurs are squeezed into limited protected areas; 38 species are critically endangered. Fuel-efficient stoves are being introduced to encourage people to reduce wood use and protect forest habitat.
All rights reserved. Animals Vanishing. What we lose when animals go extinct Animals are disappearing at hundreds of times the normal rate, primarily because of shrinking habitats. No trace of the wild South China tiger, Panthera tigris amoyensis critically endangered, possibly extinct in the wild , has been seen for more than a decade.
Zoos hold fewer than in breeding programs. If a Chinese plan to return some to the wild fails, they could become the fourth subspecies of tiger to go extinct. This story appears in the October issue of National Geographic magazine. Red panda, Ailurus fulgens fulgens endangered. But on a expedition in Bolivia, scientists captured five more—including three potential mates. Sehuencas water frog, Telmatobius yuracare vulnerable For 10 years this frog, called Romeo, was thought to be the last of his kind.
The last live one was seen in the wild in Atossa fritillary, Speyeria adiaste atossa not evaluated This California butterfly lost habitat to grazing and drought and is considered to be extinct.

Culture Vanishing Inside the homes and minds of fossil collectors These long-extinct, fearsome creatures are turning up in living rooms and corporate offices as wealthy collectors indulge a controversial hobby. Relocating animals to create new populations could bolster some species but poses new risks.

According to a study for the U. Already, a number of industries have been economically impacted by species loss. Atlantic cod in the waters off of Newfoundland formed the basis of the local economy since the 15 th century — until overfishing the cod destroyed the livelihoods of local fishermen.
Extinction is hard to see. Past generations would regard what we see as natural today as terribly damaged, and what we see as damaged today, our children will view as natural. Wooddell believes the most important thing one can do is to put pressure on Congress and elected leaders to create land management, pollution and other sustainable policies that will protect biodiversity and the environment.
A tortoise shell mirror Photo: Housing Works. Correction: This post was updated on April 3, to remove a sentence about cownose rays devastating scallop populations off of North Carolina. It turns out that other studies have challenged those findings. The Trump administration has put forth new rules that will significantly weaken the Endangered Species Act. What happened when something like the Dodo went extinct? When I think about extinction, I always wonder what would have happened if the dinosaurs had not become extinct.
I am late to the discussion about keystone species but since I have learned about the roles of these key animals to specific environments around the world I have tried and failed to see homo sapiens as a keystone species but rather I see us more like the ungulates, which when left unchecked by a corresponding predator, such as the wolf in the Yellow Stone Park scenario, would decimate any environment we occupy.
We are overpopulating, over consuming, over producing items that are harmful to the entire world such as plastics and what will keep us in check? Who will be our wolves? If humans disappeared from the earth, just suddenly vanished, I think the earth and all her flora and fauna would recover quickly. Our intelligence should curb our avarice, but I fear we are too shortsighted and too quick to rationalize away the science which spells out the looming disaster brought on my our ignorance and greed.
Endangered species are important. In my opinion, their absence can cause a break in the food chain or break synergies with other species, and thus a negative impact on them. One species and can change so much. Like a domino effect. We should take care of every species. I have been searching for a reasonable explanation of preservation of endangered species, and the search continues still.
Tigers, Elephants, Rhinos, Deers etc. Whereas, deforestation, excessive usage of fossil fuels, phytoplankton extinctions leading to global warming effects are easily understood, no such wide range of explanations and outcomes do exist on the extinction of species and their wide range of influences.
