1 . At a large forest park in eastern Beijing, 11 birds on the state-level protection list were recently released.
These birds had recovered after the Beijing Wildlife Rescue and Rehabilitation Center rescued and took care of them. “We will speed up our efforts to push the establishment of district-level wildlife rescue centers to jointly guard the health of wildlife,” said Du Lianhai, director of the center.
The center was set up in 2001 and built a wildlife rescue base in the capital’s Shunyi District in 2005. Staff at the base have rescued and rehabilitated over 30,000 wild animals in total.
Wildlife protection has been strengthened in Beijing in recent years. On June 1, the city’s newly adopted regulation on wildlife protection took effect, introducing stricter and more concrete measures to protect the environment and wildlife.
For example, the regulation states clearly that Beijing bans hunting throughout the year, compared with the previous regulation which bans hunting during the periods of March to May and September to November each year. The new regulation also gives severer punishment for poachers.
After years of monitoring, data with the Beijing Gardening and Greening Bureau recently showed ecological reconstruction progress. The species and quantity of wild animals in Beijing are continuously increasing, with the number of terrestrial spinal wild animals (陆地脊椎野生动物) growing from 461 species in 1994 to more than 500. The habitat of the endangered bird has expanded from Fangshan District to the whole city, according to the bureau.
“The enforcement of the new regulation marked a new phase in Beijing’s wildlife protection work,” said Dai Mingchao, deputy director of the Beijing Gardening and Greening Bureau.
“We will step up the publicity of the regulation and raise citizens’ awareness of wildlife protection,” Dai said. “In our integrated protection of mountains, rivers, forests, farmlands, lakes and grasslands, we take into full consideration the requirements of food-chain construction, ecological corridor construction, and wildlife and their habitat protection.”

2 . To learn to think is to learn to question. Those who don't question never truly think for themselves. These are simple rules that have governed the advancement of science and human thought since the beginning of time. Advancements are made when thinkers question theories and introduce new ones. Unfortunately, it is often the great and respected thinkers who end up slowing the progress of human thought. Aristotle was a brilliant philosopher whose theories explained much of the natural world, often incorrectly. He was so esteemed by the scientific community that even 1，200 years after his death, scientists were still trying to build upon his mistakes rather than correct them!
Brilliant minds can intimidate upandcoming thinkers who are not confident of their abilities. They often believe they are inferior to the minds of giants such as Aristotle, leading many to accept current paradigms instead of questioning them.
I, like many thinkers of the past, once believed in my mental inferiority. I was certain that my parents, my teachers-adults in general-were always right. They were like a textbook to me; I didn't question what was written on those pages. I respected them, and accepted whatever they told me. But that attitude soon changed. My mind's independence was first stimulated in the classroom.
A stern, 65yearold elementaryschool science teacher once told me that light is a type of wave. I confidently went through years of school believing that light is a wave. One day，however I heard the German exchange student mention that light could be made up of particles. As the others laughed at his statement, I started to question my beliefs.
Maybe the teachers and textbooks hadn't given me the whole story. I went to the library, did some research and learned of the lightasawave versus lightasaparticle debate. I read about Einstein's discovery of the dual nature of light and learned the facts of a paradox(悖论) that puzzles the world's greatest thinkers to this day. Light behaves as both a particle and a wave, it is both at once. I realized I had gone through life accepting only half of the story as the whole truth.
Each new year brought more new facts, and I formulated even more questions. I found myself in the library after school, trying to find my own answers to gain a more complete understanding of what I thought I already knew. I discovered that my parents and teachers are incredible tools in my quest for knowledge, but they are never the final word. Even textbooks can be challenged. I learned to question my sources, I learned to be a thinker. I once believed that everything I learned at home and at school was certain, but I have now discovered to reexamine when necessary.
Questions are said to be the path to knowledge and truth, and I plan to continue questioning. How many things do we know for sure today that we will question in the future? At this moment, I know that our sun will burn for another five billion years, and I know nothing can escape the gravity of a black hole. This knowledge, however, may change in the next 20 years-maybe even in the next two. The one thing we can control now is our openness to discovery. Questions are the tools of open minds, and open minds are the key to intellectual advancement.

3 . The first time a tortoise walked through my hut at Middle Camp on Aldabra Atoll, I was amazed. I grabbed my camera and carefully positioned myself to take this wildlife encounter. The second time: same thing. The third time: I picked up my phone and took a snapshot. By the fourth or fifth time, I didn't even look when I felt something bump into me. I knew what it was.
I was there to shoot a story about island restoration（修复）in the Seychelles, far off the east coast of Africa in the Indian Ocean. Until roughly the middle of the past century, the small island nation showed signs of real environmental killing—local vegetation（植被）cleared to make way for coconut plantations, foreign rats and mice running uncontrolled, native sea turtles and giant tortoises being exploited. Biodiversity seemed destroyed. But then the country experienced a shift in conservation awareness — and the giant Aldabra tortoises are among its most visible signs.
Every morning when I woke up and walked outside the hut, I had to remind myself that I hadn't traveled back in time. I could see flightless Aldabra rails, coconut crabs the size of dinner plates, and giant tortoises—roughly four feet long and weighing up to 550 pounds—just wandering around. The number of sharks in the bay was crazy. Frigatebirds and boobies（鲣鸟）nested in the mangroves（a kind of tree）. When we left our hut doors open, which we often did to let in air, the tortoises would walk right through.
In the late afternoon or early evening, whenever they'd finished eating, the tortoises would drop themselves down and fall asleep with their heads outstretched. That made nighttime trips to the outhouse perilous. To get there, we'd have to go 200 feet into the mangroves, negotiating what I called the tortoise slalom （之形障碍）trail.
It was a track without a pattern, because of course they picked different places to sleep every night. Avoiding them was important: Falling headfirst over a tortoise onto the sharp coral rock could lead to serious injury on an island far from medical facilities.
Nothing was easy on Aldabra, and much of it was insanely difficult. Yet living among the tortoises in this primordial place, in one of the last spots where reptiles still rule; was one of the happiest times of my life.

4 . That morning, I dropped our eldest at kindergarten and returned home to let our two younger children play while I worked on my medical report. It was wonderful, but it hit me that my career in hospital wasn't making a difference in anyone's life. I needed something that would stretch my limits and push me to grow. My career enabled me to work from home. I could work from home, and become a foster (领养) mother, providing safety for a child who needed it desperately.
On Monday morning, I picked up the phone and dialed the number I had googled for the nearest Department of Children's Services. The man on the other end was receptive to my questions and explained the next step of training, involving eight weeks of classes designed to prepare and educate foster parents. We continued through all the classes, the home visits, background checks, and seemingly endless steps.
Five long months after we were approved, the phone rang. In the middle of the night, I woke my husband and rushed to East Tennessee Children's' Hospital. Our placement was waiting for us in the emergency room, sick and lack of nutrition. It didn't take long for us to realize the full depth of her suffering. Six months later, her half-brother came to us by our request. We now had five children under our care.
On August 12, 2016, our family of seven walked into a small courtroom. The children's lawyer and social worker were there. With just a few words, our adoption was finalized. These two amazing children weren't going home, because they were already home. We are their forever family, and they are our forever children. We may not be able to change the entire world, but we have changed the world entirely for our new children.

5 . Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧）levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicated, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.
