1 . For long, Preifer Fall Trail (路线) was a most popular attraction in Big Sur. Annually, thousands of people hiked the trail. Unfortunately, the trail, along with stairs, signs, railings, an observation station and wooden bridges, was destroyed in the 2008 Basin Complex Fire. But now a new trail has risen from the burned land.
With its amazing rocky coastline and mountains, Big Sur, the writer Henry Miller once said, is “the face of the earth as the creator intended it to look.” But the landscape always suffers natural disasters. There have been three major wildfires in Big Sur in the past years. “You can still see the impacts there,” said John Hiles, a state parks repair team leader, pointing to black marks 30 feet up a huge redwood.
Parks planners designed a new track, moving the trail out of the river to reduce its impact on the environment. People from the California protection group, state parks department and the nonprofit organization put in 66,000 hours of work over the past four years. They built 160 redwood stairs and dragged hundreds of 16-foot-long redwood sticks by hand to build railings. They removed 4,150 square feet of old building stuff, enough to cover a basketball court. They used iron cables and pulleys (缆线和滑轮) to build a 70-foot long wooden bridge over the hills. “Nature is probably the best place to learn,” Hiles said. “More than any college or school, you learn so many life lessons out here.”
However, the huge Soberanes Fire s wept through the area in 2016, putting a stop to the work. When they began again in 2017, great river storms flooded the area and damaged part of Highway 1. Everybody gathered around this project. They saw the loss. They missed it. They wanted it to come back. They kept combining efforts. It’s been a long journey, but worth the wait.

3 . As a research scholar at the Indian Institute for Science Education and Research, I once monitored birds that inhabited grasslands in Daying Ering Memorial Wildlife Sanctuary, a protected area in Northeast India. This habitat forms a part of one of the most bio-diverse places on Earth. Yet despite their ecological importance and uniqueness, most grasslands are classified by the Indian government as “wastelands”.
Ecosystems throughout the world are suffering from the effects of unchecked habitat loss and climate change. While all types of ecosystems—forests, grasslands, oceans, wetlands and deserts—feel these effects, there is evidence of bias (偏好) towards the conservation of forest biodiversity. This bi as hurts the preservation of other ecosystems, including the grasslands that make up 24 percent of the Indian landmass. These grasslands are home to important biodiversity and support the livelihoods of millions of people, yet are defined in India by their value in being turned into forests for fighting climate change.
Apart from being costly, the move overlooks the ecological and social value of grasslands by turning them into mono-culture forests, which do not provide the same ecological benefits. Yet, grasslands could be equally good at storing carbon.
India and other countries with substantial grasslands need to recognize, support and prioritize evidence-based scientific attempts that focus on grasslands by establishing grassland-specific restoration efforts, as well as by mapping their extent and the ecosystem services they provide for humans. The time is ripe for abandoning outdated labelings like “wastelands”.
Already, communities like the Todas and the Idu Mishmi people are protecting grasslands in India through collective action and local stewardship (管理), which are helping them connect with the grasslands. With the aim of preserving the richness of nature, the government must restore greater rights to local communities to manage grasslands. Grasslands are an important feature of an ecologically sound India, one that must be preserved for that value above all others.

5 . Have you ever enjoyed a trip to a zoo, but wondered whether it is acceptable for humans to keep so many treasured animals in cages. You are not alone. Many people concerned about the fate of zoo animals and feel conflicted about the very existence of zoos. However, there is no reason to worry.
Most zoos around the world provide the highest level of care and cleanliness for their animal residents. In fact, animals in zoos often experience far healthier lives than they would in the wild due to the access to medical care.
Zoos provide opportunities for people of all ages to view and connect with animal life that they would otherwise not encounter. By interacting with wild life, people can gain a greater appreciation for the animals of the world. Zoos offer educational experiences through which people can learn why it is so important to protect and maintain the diversity of animal life on Earth.
Zoos also function as places where these often rare or endangered animals can be studied. By keeping and raising animals in cages, extensive research can be conducted on the animals to help scientists understand them. This scientific understanding, in turn, contributes to conservation efforts around the world. Because zoos are a safe place for animals to be observed, scientists are able to make important discoveries about their lives.
While it is true that not all zoos are as well maintained and equipped, there is growing international pressure for universal regulations that will ensure the monitoring of all public zoos. This type of legal support will allow the world’s zoos to continue their important research programs, many of which are adjusted toward breeding programs designed to make more endangered species come in. Breeding programs are essential to continue certain species which are nearly wiped out from the wild, and zoos are the ideal place for these programs to promote the increase of the animals. In this manner, zoos contribute to restoring balance in the wilderness by giving endangered species a second-chance at survival.
If you visit a top-ranking zoo, you will enjoy viewing animals in a habitat designed to support their health. You can rest assured that by supporting such zoos as a visitor, you are also supporting valuable science and conservation efforts. Your interactions with the animals and exhibits might educate you further about creatures in parts of the world you haven’t been exposed to.
When people are inspired, they tend to take action more readily, and zoos are an inspiring example of this truth. Zoos provide an unforgettable experience in appreciating animal life and take concrete action towards advocating for their future.

___________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________7 . Jace Tunnell, the founder of Nurdle I troll and Reserve Director at the University of Texas Marine Science Institute, is listening to the same question often.
“I hear every day, somebody says, ‘What is a nurdle?’” he said.
Tunnell explained nurdles are tiny balls of plastic that are typically used to make almost every plastic item we use, so they’re everywhere! He said nurdles are usually spilled (溢出) during transport from cargo ships or railroad cars. “These things would be out here for hundreds of years if we’re not picking them up,” Tunnell said while on a recent Nurdle Patrol cleanup along Galveston Bay.
Since 2018, Nurdle Patrol has grown to thousands of volunteers worldwide. Many people -volunteer with Nurdle Patrol and work for the Galveston Bay Foundation. Nurdle Patrol groups upload their findings to the nonprofit’s website map. It’s marked in colors to show where the highest concentration of nurdles is found.
“They look natural, and birds think that they’re food,” Tunnell said, “Birds, fish, sea turtles and other sea animals can eat nurdles and finally die from hunger because of a false sensation of fullness and lack of nutrition.”
I ended up finding 123 nurdles in 10 minutes. That’s high concentration,” Tunnell said about a recent cleanup. “I plan to take those to an elected official and say, ‘Look, these are what I found on our beaches here. We need to do something about this.’ So, it kind of puts in motion change that can happen.”
Nurdle Patrol has sent out hundreds of kits (工具包) globally, many to schools and volunteer organizations, with information about gathering nurdles and reporting the findings safely. Anyone can request a kit through their website.

8 . The sunflower sea star has been listed as a critically endangered species following a groundbreaking population study led by Oregon State University (OSU) and The Nature Conservancy.
“These giant sea stars used to be easy to find and were a hit with divers. Unfortunately, your chances of finding one now are next to nothing in most of the areas near the United States—this listing is one step to extinction—and I don’t think they’re coming back without help,” said OSU’s Sarah Gravem, a research associate in the College of Science and the lead author of the study.
Populations of the sunflower sea star suffered dramatic crashes because of a marine (海洋的) wildlife epidemic event, which began in 2013. Scientists used more than 61,000 population surveys from 31 data sets to calculate a 90.6% decline in the sunflower sea stars and estimated that as many as 5.75 billion animals died from the disease, whose cause has not been determined. Moreover, the research showed no sign of population recovery in any region in the five to seven years since the event.
Sunflower sea stars are a key catcher of purple sea urchins (海胆) and the sea star decline has helped the increase in the urchin population in many regions. Too many urchins are linked to a decline in kelp forests(海藻林) already facing pressure from marine heat wave events, making the future uncertain for ecosystems that provide habitat for thousands of marine animals and help support coastal economies.
“Because most people are not out in the ocean every day, we don’t realize how much it’s being changed and impacted by humans. We need to think about how to keep our ocean healthy. While reducing the release of carbon dioxide is the most pressing need, rebuilding key catcher populations, like the sunflower sea star, can be an important piece of the puzzle too,” said study co-author Sara Hamilton, a Ph. D. candidate in the OSU College of Science.

9 . On November 7, Lewis Pugh completed a one-kilometer swim in the freezing waters of King Edward Cove, off South Georgia in Antarctica. He was wearing only his swimming glasses, cap and Speedos!
Pugh is an advocate for our oceans and seas, working to protect these ecosystems with their large diversity of marine (海洋的) life. When asked why he doesn’t wear a wetsuit (防寒泳衣), Lewis says, “I ask world leaders to do everything they can to protect our oceans. Sometimes the steps they need to take are difficult and unpopular. If I’m asking them to be courageous, I must also be. Swimming in a wetsuit would not send the right message.”
It took Pugh about 19 minutes to complete the one-kilometer swim in Antarctica where the water averaged about 1. 6℃. He says that his body can only tolerate about 20 minutes in the freezing waters before it starts shutting down. As he swims, his body temperature steadily drops, which in turn causes his muscle control to drop, slowing him down. When he is done with his swim, his support team rushes him to a hot shower and it takes almost an hour for his body temperature to return to normal.
Doctors and Pugh caution that one must receive months of training to swim in such cold waters. Even expert swimmers who are unused to freezing water can drown within minutes because of the physical shock experienced by the body. Pugh says he trained for six months before this swim.
This is not the first time that Lewis has swum in dangerous conditions. In 2007, he swam one kilometer in the North Pole to draw attention to the melting Arctic ice due to climate change. In 2015, he swam in the Bay of Whales in Antarctica’s Ross Sea as part of his successful campaign to help set up a marine reserve there.
