3 . During the last week of Fu Bao’s public viewing earlier this month, visitors endured waiting for 5—6 hours just to give a glance at the panda for only five minutes, as Everland Panda World restricted viewing time to manage the flood of visitors.

Born to parents Ai Bao and Le Bao in July 2020, Fu Bao is South Korea’s first naturally-born panda. In the days following her birth, Everland’s social media channels offered fans a steady diet of Fu Bao videos, pulling in more than 1.2 million subscribers and, as of February, over 500 million accumulated views. The most recent videos are now filled with warm and sincere messages from viewers.

Thanks to Fu Bao’s widespread popularity, her zookeeper has also found himself in the spotlight, becoming a bit of a social media star himself. Often referred to as her grandpa, Kang Chul-won offered hi own farewell message to Fu Bao, noting that the South Koreans’ special love for her all began with social media videos shared during the pandemic when the zoo was closed. She brought help and happiness to a society in many ways that was having a difficult time due to the virus. He said people visited the social media sites every day so it felt like he was raising her together with them. They cared so much for her and shared the same emotions of raising a baby panda together during such difficult times.

Fu Bao will be transferred to China Conservation and Research Center for the Giant Panda in Sichuan Province. Everland says that she will be kept alone at Everland Panda World for a month to prepare her to adjust to her new environment before her overseas transfer, which will be carried out in accordance with international rules.

5 . Ten years ago, environmental journalist Ben Goldfarb was on a reporting trip about wildlife conservation. When he was shown around some new animal crossing structures near, Missoula, these new bridges and tunnels intrigued him. He was attracted by these beautiful human-built structures and inspired to write a book. Crossings: How Road Ecology Is Shaping the Future of Our Planet has now been published.

Through expert interviews, in-depth research and convincing analysis, Goldfarh brings to life the deadly consequences our 40 million miles of roadways have had and are having on the natural world and the creatures that inhabit it. A million animals are killed by cars each day in the US alone. Road salt pollutes lakes and rivers. And there's the barrier effect-the steady stream of traffic that prevents animals from migrating (迁徙) all together and finding habitats. Goldfarb writes that noise pollution is the most worrisome among all the road's ecological disasters. Both the engine noise and the tire noise greatly impact ecological environment.

Figures on deaths and disruptions (扰乱) are disheartening, but Goldfarb vividly describes how scientists are actively working on meaningful improvements to help animals and roads better coexist, such as wildlife crossings, from passages in Canada's Banff National Park to the famous Liberty Canyon Overpass in Los, Angeles. Another example is that in India, they built a new highway through a tiger reserve so that animals can come and go underneath the lifted freeway. Of course, that made the project more expensive, but it's ecologically the right thing to do.

Crossings is a truly important and landmark book on a subject whose full impacts continue to be disregarded or underestimated in considering conservation efforts. The book is a sympathetic, heart-warming guide to exploring the issues of wildlife survival and our own.

6 . A British company has proposed releasing a GM(genetically modified) strain of the diamondback moth (菱形斑纹蛾), which has been developed to help reduce the population of these vegetable-eating insects.

Male diamondback moths carrying a deadly gene would be released which would cause their off springs (后代) to die almost immediately. Then the fall in their numbers could help to increase crop yields for farmers.

Oxitec, the company which came up with the idea, hopes to begin trials next year but faces opposition from groups who say the untested technology could threaten wildlife and human health.

“Mass releases of GM insects into the British countryside would be impossible to recall if anything went wrong. Changing one part of an ecosystem can have knock-on effects on others in ways that are poorly understood. This could include an increase in different types of pests. Wildlife that feeds on insects could be harmed if there are changes to their food supply” said Dr Helen Wallace, the director of Gene-Watch UK, who has sat on government advisory bodies.

Hadyn Parry, Oxitec’s chief executive, said there was demand from farmers for the technology and that using GM insects to kill the pests that feed on food crops is better for the environment than chemical sprays. The firm, which is supported by grants from the taxpayer, is developing a number of GM insects that would be used in Britain and around the world to protect crops and combat disease in humans.

Oxitec has contacted the Health and Safety Executive (HSE) to ask what controls, if any, should be put in place around GM moth trials. A spokesman said that while its officials and advisers have discussed Oxitec’s plans, there is yet to be a formal application for a trial. Consequently the department has not reached a view on whether it should go ahead.

8 . The ocean is home to more than 200,000 known species and as many as 2 million that we have yet to discover. And, it is also home to 24.4 trillion pieces of microplastics. In 2022, researchers spotlighted how bad marine microplastic pollution, is getting: The total amount of microplastics on the bottom of oceans has greatly increased. in the past two decades.

Microplastic particles don’t just end up at the bottom of the ocean. Animals are eating them — at least 1,500 species have been reported to ingest plastic. And a lot of it. For example, whales in New Zealand’s Hauraki Gulf consume roughly three million microplastics daily, according to research published in Science of the Total Environment, which analyzed whale waste to see how much microplastics were present.

“Other research has shown that if plastics are small enough, they can cross the gut(肠道) wall and get into internal organs though the long-term effects are still unclear. Plastics can also release chemicals that are harmful to digestive system,” says Kahane-Rapport. “This is concerning, and while we do not yet understand the long-term health-effects, it is likely not a good sign for whales and their prey(猎物) to eat a man-made material like plastic.”

This is obviously bad for whales, but it also has effects on humans and the ocean at large. We are also part of these food chains and are consuming microplastics regularly. They are in our bottled water, in our table salt — they are even in our house dust and in the air we breathe. And we still don’t know what the health effects are. Meanwhile, the impact on whales — and what it indicates — is troubling on many fronts. “Whales are ecosystem engineers,” says Kahane-Rapport. “They can spread the nutrients that they consumed and serve as ecosystem guards — when whales are not healthy, other parts of the system will suffer.”

Kahane-Rapport says more research is needed. “The next research step will be to determine how much plastic the whales excrete(排出) and how much is left in their bodies. Following that, we would be able to determine the direct health effects on their tissues.”

9 . Wind turbines (风力发电机) work especially well out in coastal waters, where ocean winds can be very strong. Offshore wind farms cost more to build than onshore ones. Offshore equipment must be heavier than onshore equipment. It has to stand up to very heavy winds, big waves and strong currents. Sending people to install, operate and repair equipment at sea is costly. But once set up, offshore wind could pick up bonus tasks.

According to Haris Ishaq, an engineer at the University of Victoria in Canada, one of the best add-ons to wind farms is making hydrogen gas, which means making a clean power source in a clean way. A device called an electrolyzer (电解器) can split water into hydrogen and oxygen. The electrolyzer needs fresh water, not salt water. To remove the sea salt, Ishaq’s team proposes removing the salt through a special technique, which is supposed to run on the electricity produced by the offshore wind farms.

Ishap’s group also proposes adding a second bonus task to wind farms—to capture (捕获) CO₂ from the atmosphere. Atmospheric CO₂ levels are higher than ever, resulting in a worsening greenhouse effect. A process called direct air capture, or DAC, can remove CO₂ from the air. The DAC devices need electricity to run. Fans move air across a solid material that captures CO₂ and releases everything else. When the solid material is heated to 100° Celsius, it releases the stored CO₂. The same solids can then be reused to grab more CO₂. The electricity made by wind turbines would power the devices’ fans and the electric boiler, to heat the carbon-collecting solid. To store the CO₂ released, Ishaq’s team proposes injecting it into a type of deep-sea rock. That rock reacts with the gas, turning it into more rock in 10 to 25 years.

Ishaq’s team modeled wind turbines, electrolyzers and DAC units on computers to confirm their proposed system is a good idea. The next step is to test a small version of this set up on a floating platform in the ocean.
