This morning we're going to head off down into the wetland, into a very specific kind of wetland called the Prairie fen.
You can find Nate Fuller counting butterflies. The Sarett Nature Center needs an accurate count of Mitchell's satyr butterflies to help preserve one of their last known habitats. They're very particular about the kind of habitat where they can live, which is part of what makes them so rare and amazing indicators for our water quality. Today, Sarett expert Ashley Cole-Wick with Michigan's Natural Features Inventory helps Fuller count. She says "When I first started working on the butterfly in 2013, we had 18 populations and this year in 2019, we have 10."
The Mitchell Seder went on the endangered species list in 1991. Initially it was thought that loss of wetlands contributed to their decline. Fuller says "It's not just habitat availability. Its groundwater and the amount in the quality of groundwater coming into these wetlands seem to be a challenge for the butterfly. Nothing has all been sorted out exactly. ” While the decline is likely a combination of factors. the fact that water quality might contribute is alarming because the wetlands are the headwaters for the Midwest's rivers and streams.
A captive breeding （人工繁殖）program was started four years ago at the Toledo Zoo to help get to the bottom of the mystery. Today Director Ryan Walsh who heads the program says it's been, the only successful captive program. The caterpillars （毛毛虫）spend the winter in a special weather control room that help determine the Mitchell satyrs don't do well below 4. 4 degrees Celsius, a temperature that prevents the Fen wetlands from the hard freezes which kill the insects. With that knowledge, the program produced 1300 new eggs this summer, a development that may go a long way toward restoring the population. And if all goes well, may one day the Mitchell satyr butterfly earn a ticket off Endangered Species List.

"Ma uka, ma uka ka ua , Ma kai, ma kai ka ua." So sing the children at a kindergarten on the Island of Hawaii. The song is much like "Rain, rain, go away” nursery rhyme, but it has an unusual power: it is one of the tools that have revived a near-dead language.
The decline of Hawaiian was not, as is the case with most disappearing languages, a natural death caused by migration（迁徙）and mass media. In 1896, after American business interests ended the Hawaiian original political system， schools were banned from using it. By the late 20th century, apart from a couple of hundred people on one tiny island, English had replaced Hawaiian and only the old spoke it to each other.
The civil-rights movement brought a revival of interest among the young, centred on the University of Hawaii at Hilo. Larry Kimura, a professor there, was not satisfied that the language should be only a subject at college： he and his students wanted to bring it back to life. The idea for how to do that came from a visiting Maori, who suggested. “language nests", which had successfully revived New Zealand's native language.
In 1985, when educating children in Hawaiian was still banned, Kauanoe Kamana and her husband Pila Wilson, both students of Kimura's, created the first Language nest" at Hilo. Neither was a native speaker, but both were determined, to bring up their children, as such. They gathered a small group of children, including their own son and daughter, and elderly native speakers.
The movement grew： there are now 12 kindergartens and 23 schools involved. The number of children being educated in Hawaiian has risen from 1, 877 in 2008 to 3.028 in 2018. Along with Japanese, Hawaiian is the non-English language most commonly spoken among children.

Han Tianheng picked up a carving knife at the age of 6 and never put it down. Today, the 79 year-old artist, one of China's most respected living masters of seal carving（印章雕刻）, calligraphy and Chinese painting, still remembers the incident the first time he held a knife in his hand.
“I cut my thumb badly and was horrified by the bloody sight," he said, adding that his mother applied ashes because she couldn't afford to take him to a hospital. "The cut left a scar, which is still clear today."
An eye for an eye and blood for blood, the incident didn't set him back. Instead, it aroused his passion for the ancient art form. He was determined to pursue a path that would lead to a career in seal carving. Han said.

"This time, he asked me to carve a seal for him. This was positive affirmation," Han said. "Praise and criticism are what an artist should learn to handle all his life. Praise is candy and criticism is medicine. We can live without candy, but cannot live without medicine when ill."
Han rose to fame during the early 1960s famous for bird and insect seal art. Han's seals are an essential ending part on the paintings of a long list of well-established artists.
“A seal for a good painting is. like the buttons for an haute couture(高档女子时装).An experienced tailor always knows how to choose buttons that matches the whole style," Han said
His seals are full of variety — grand and solemn for Liu Haisu's paintings, light and vivid for Lu Yanshao's, graceful and gentle for Xie Zhiliu's.
"A good seal carver should keep bis own style, and at the same time go well with the painting's style." he said.
