It’s a typical Snoopy card: cheerful message, bright colors, though a little yellow and faded now. Though I’ve received fancier, more expensive card over the years, this is the only one I’ve saved. One summer, it spoke volumes to me. I received it during the first June I faced as a widow to raise two teenage daughters alone. In all the emotional confusion of this sudden single parenthood. I was overwhelmed with, of all things, the simplest housework: leaky taps, oil changes, even barbeques (烧烤). Those had always been my husband’s jobs. I was embarrassed every time I hit my thumb with a hammer or couldn’t get the lawnmower (割草机) started. My uncertain attempts only fueled the fear inside me: How could I be both a father and mother to my girls Clearly, I lacked the tools and skills. On this particular morning, my girls pushed me into the living room to see something. (I prayed it wasn’t another repair job. ) The "something" turned out to be an envelope and several wrapped bundles on the carpet. My puzzlement must have been plain as I gazed from the colorful packages to my daughters’ bright faces. "Go ahead! Open them! "They urged. As I unwrapped the packages, I discovered a small barbecue grill(烧烤架) and all the necessary objects including a green kitchen glove with a frog pattern on it. "But why " I asked. "Happy Father’s Day! " they shouted together. "Moms don’t get presents on Father’s Day. " I protested. "You forgot to open the card. " Jane reminded. I pulled it from the envelope. There sat Snoopy, on top of his dog house, merrily wishing me a Happy Father’s Day. "Because," the girls said, "you’ve been a father and mother to us. Why shouldn’t you be remembered on Father’ s Day" As I fought back tears, I realized they were right, I wanted to be a "professional" dad, who had the latest tools and knew all the tricks of the trade. The girls only wanted a parent they could count on to be there, day after day, performing repeatedly the maintenance tasks of basic care and love. The girls are grown now, and they still send me Father’s Day cards, but none of those cards means as: much to me as that first one. Its simple message told me being a great parent didn’t require any special tools at all -just a willing worker.

Madagascar There are at least 8 million unique species of life on the planet, if net far more, and you could be forgiven for believing that all of them can be found in Andasibe. Walking through this rain forest in Madagascar is like stepping into the library of life. Sunlight seeps through the silky fringes of the Ravenea louvelii, an endangered palm (棕榈树) found, like so much else on this African island, nowhere else. Madagascar which separated from India 80 million to 100 million years ago before eventually settling off the southeastern coast of Africa, is in many ways an Earth apart. All that time in geographic isolation made Madagascar a Darwinian playground, its animals and plants evolving into forms utterly original. Some 90% of the island’s plants and about 70% of its animals arc endemic, meaning that they arc found only in Madagascar. But what makes life on the island unique also makes it uniquely vuhnerable, which means if we lose these animals on Madagascar, they’re gone forever. That loss seems likelier than ever because the animals are under threat as never before. Once lushly forested, Madagascar has seen more than 80% of its original vegetation cut down or burned since humans arrived at least 1500 years ago, fragmenting habitats and leaving animals effectively homeless. Unchecked hunting wiped out a number of large species, and today mining, logging and energy exploration threaten those that remain. It has an area the size of New Jersey in Madagascar that is still under forest, and all this incredible diversity is crammed into it. Madagascar is a conservation hot spot a term for a region that is very biodiverse and particularly threatened--and while that makes the island special, it is hardly alone. Conservationists estimate that extinctions worldwide are occurring at a pace that is up to 1 000 times as great as history’s background rate before human beings began scattering. Worse, that die-off could be accelerating. Price of Extinction There have been five extinction waves in the planet’s history—including the Permian (二叠纪的) extinction 250 million years ago, when an estimated 70% of all terrestrial animals and 96 % of all marine creatures vanished, and, most recently, the Cretaceous (白垩纪的) event 65 million ),ears ago, which ended the reign of the dinosaurs. Though scientists have directly assessed the viability of fewer than 3% of the world’s described species, the sample polling of animal populations so far suggests that we may have entered what will be the planet’s sixth great extinction wave. And this time the cause isn’t an unsteady planet or volcanoes. It’s us. Through our growing numbers, our thirst for natural resources and, most of all, climate change-- which, by one reckoning, could help carry off 20% to 30% of all species before the end of the century-- we’re shaping an Earth that will be biologically exhausted. A 2008 assessment by the: International Union for Conservation of Nature found that nearly 1 in 4 mammals worldwide were at risk for extinction, including endangered species. Over fishing and acidification of the oceans are threatening marine species as diverse as the corals. Scary for conservationists, yes. but the question arises: Why should it matter to the rest of us After all, nearly all the species that were ever alive in the past are gone today. Evolution demands extinction. When we’re using the term extinction to talk about the fate of the US auto industry, does it really matter if we lose species like the Yangtze River dolphin and the golden toad, all of which have effectively disappeared in recent years What docs the loss of a few species among millions matterFor one thing, we’re animals too, dependent on this planet like every other form of life. The more species living in an ecosystem, the healthier and more productive it is, which matters for us--a recent study by the World Wildlife Fund (WWF) estimates the economic value of the Amazon rain forest’s ecosystem services to be up to $100 per hectare (about 2.5 acres). When we pollute and deforest and make a mess of the ecological web, we’re taking out mortgages on the Earth that we can’t pay back--and those loans will come due. Then there are the undiscovered organisms and animals that could serve as the basis of needed medicines as the original ingredients of aspirin were derived from the herb meadowsweet unless we unwittingly destroy them first. Forests razed can grow back., polluted air and water can be cleaned, but extinction is forever. And we’re not talking about losing just a few species. In fact, conservationists quietly acknowledge that we’ve entered an age of triage (挑选), when we might have to decide which species can truly be saved. The worst-case plot of habitat loss and climate change and that’s the pathway we seem to be on-show the planet losing hundreds of thousands to millions of species, many of which we haven’t even discovered yet. The result could be a virtual extinction of much of the animal world and an irreversible poverty of our planet. Hmnans would survive, but we would have doomed ourselves to what naturalist E.O. ’Wilson calls the Eremozoic Era the Age of Loneliness. So if you care about tigers and rhinos, if you believe Earth is more than just a home for 6.7 billion human beings and counting, then you should be scared. But fear shouldn’t leave us paralyzed. Environmental groups worldwide are responding with new methods to new threats to wildlife. In hot spots like Madagascar and Brazil. conservationists are working with locals on the ground, ensuring that the protection of endangered species is tied to the welfare of the people who live closest to them. A strategy known as avoided deforestation goes further, incentivizing environmental protection by putting a price on the carbon locked in rain forests and allowing countries to trade credits in an international market, provided that the carbon stays in the trees and is not cut or burned. And as global warming forces animals to migrate in order to escape changing climates, conservationists are looking to create protected corridors that would give the species room to roam. It’s uncertain that any of this will stop the sixth extinction wave, let alone preserve the biodiversity we still enjoy, but we have no, choice but to try. We have a window of opportunity, but it’s slamming shut. To Save the Species, Save the People Madagascar, which is called the "hottest of the hot spots", is where all the new strategies can be road tested. In 2003, after decades when conservation was barely on the government’s agenda, then-President Marc Ravalomanana announced that the government would triple Madagascar’s protected areas over the following five years. That decision helped under funded parks like Andasibe’s, which protects some of the last untouched forest on the is land. "You can’t save a species without saving the habitat where it lives," says WWF’s Roberts. Do that right, and you can even turn a profit in the process. In Madagascar, half the revenues from national parks are meant to go leo the surrounding communities. The reserves in turn help sustain an industry for local guides. In a country as poor as Madagascar, where 61% of the people live on less than $1 a day, it makes sense to give locals an economic stake in preserving wildlife rather than destroying it. The corridors created by CI’s Andasibe tree-planting program show how a small tweak can reduce the species killing effects of climate change--but also how longer-term fixes are needed. Fragmented habitats are problematic because many endangered species wind up trapped in green oases surrounded by degraded land. As global warming changes the climate, species will try to migrate, often right into the path of development and extinction. What good is a nature reserve--fought for, paid for and protected--if global warming renders it unlivable Climate change could undermine the conservation work of whole generations. It turns out you can’t save species without saving the sky. That will mean reducing carbon emissions as fast as possible. In the US, the CBD has made an art out of using the Endangered Species Act, which mandates that the government prevent the extinction of listed species, to force Washington to act on global warming. The CBD’s Siegel led a successful campaign to get the Bush Administration to list the polar bear as threatened by climate change, and we expect more species to follow. What can we find in Andasibe
It’s no surprise that Jennifer Senior’s insightful, provocative magazine cover story, "I Love My Children, I Hate My Life," is arousing much chatter—-nothing gets people talking like the suggestion that child rearing is anything less than a completely fulfilling, life-enriching experience. Rather than concluding that children make parents either happy or miserable, Senior suggests we need to redefine happiness: instead of thinking of it as something that can be measured by moment-to-moment joy, we should consider being happy as a past-tense condition. Even though the day-to-day experience of raising kids can be soul-crushingly hard, Senior writes that "the very things that in the moment dampen our moods can later be sources of intense gratification and delight. " The magazine cover showing an attractive mother holding a cute baby is hardly the only Madonna-and-child image on newsstands this week. There are also stories about newly adoptive—and newly single-morn Sandra Bullock, as well as the usual "Jennifer Aniston is pregnant" news. Practically every week features at least one celebrity morn, or mom-to-be, smiling on the newsstands. In a society that so persistently celebrates procreation, is it any wonder that admitting you regret having children is equivalent to admitting you support kitten-killing It doesn’t seem quite fair, then, to compare the regrets of parents to the regrets of the children. Unhappy parents rarely are provoked to wonder if they shouldn’t have had kids, but unhappy childless folks are bothered with the message that children are the single most important thing in the world: obviously their misery must be a direct result of the gaping baby-size holes in their lives. Of course, the image of parenthood that celebrity magazines like Us Weekly and People present is hugely unrealistic, especially when the parents are single mothers like Bullock. According to several studies concluding that parents are less happy than childless couples, single parents are the least happy of all. No shock there, considering how much work it is to raise a kid without a partner to lean on; yet to hear Sandra and Britney tell it, raising a kid on their "own" (read: with round-the-clock help) is a piece of cake. It’s hard to imagine that many people are dumb enough to want children just because Reese and Angelina make it look so glamorous: most adults understand that a baby is not a haircut. But it’s interesting to wonder if the images we see every week of stress -free, happiness -enhancing parenthood aren’t in some small, subconscious way contributing to our own dissatisfactions with the actual experience, in the same way that a small part of us hoped getting "the Rachel" might make us look just a little bit like Jennifer Aniston.
