1 . The Indian government declared an “emergency situation” in New Delhi on Sunday as air pollution hit dangerous new highs and people had the selfies(自拍) to prove it.

Officials announced a series of measures to fight against smog in the capital city, including halting construction projects, closing a coal-fired power factory for 10 days and washing the dusty roads. The citizens，meanwhile，took “smog selfies” as they walked through dirty air which could taste and smell. Some selfie photographers joined hundreds of protesters in downtown New Delhi to demand that the government deal with the deadly smog.

New Delhi, already one of the world’s dirtiest cities, is experiencing its worst smog in nearly two decades. The city saw levels of PM2.5 of more than 900 micrograms per cubic meter on Saturday. That’s more than 90 times the level that the World Health Organization considers safe and is 15 times higher than the Indian government’s standards.

Particulate(微粒的) matter comes from vehicles, coal factories, burning trash piles, dust and other sources. New Delhi’s severe pollution was initially blamed on the widespread bursting of firecrackers during the festival Diwali. But images published by NASA last week suggested that crop burning in the neighboring states of Punjab and Haryana could be the reason for the increasing levels of PM2.5. New Delhi’s chief minister, Arvind Kejriwal, said that farmers in those states begin burning straw at the start of every winter to clear their plants for planting wheat.

The pollution can lead to lung cancer, heart disease and related illnesses, particularly in growing children. Kejriwal said people should avoid going outdoors until the pollution levels drop and should work at home as much as possible. Of course, they should put down the selfie sticks, too.

3 . Despite Kyle Tianshi being only a 15-year-old US high schooler, he has published five sci-fi novels. His fifth book Eventide was released in July. However, this may not be his most impressive achievement as Kyle just received the “Hero Award”, a $20, 000 grand prize. It is the top honor in the California Youth Sustainability Awards. The competition aims to encourage and support young community leaders who are making a difference for sustainability in their communities by taking action for the planet.

Kyle, a sophomore from the Cambridge School in the US, received the honor for his portable invention called NEREID. The device can detect microscopic particles (粒子) in water by using a laser and microscope. These particles can be harmful to people and the environment.

Kyle came up with the idea for the invention based on his experience growing up in San Diego, California, US. People had no access to unpolluted drinking water and his parents asked him not to drink tap water. Kyle spent about $60 buying the tools needed to analyze the tap water: a laser, a microscope and a micro-computer. “It’s incredibly powerful for the price,” Kyle said. Then he used their family’s garage as his laboratory, doing research on the pollution of drinking water caused by micro-plastics.

Kyle hopes to bring to market a low-cost alternative tool for detecting micro-plastic pollution levels in drinking water. In this way, he can offer help to people who don’t have access to water filtration (过滤) systems. He has applied for a patent.

Kyle said his sister Emily, a freshman at Stanford University, inspired his interest in environmental research. She was recognized nationally for developing a water collection device. They have founded the Clearwater Innovation program to advocate for clean water through social media platforms and organize community cleanup events.

5 . Newcastle University research is helping to prepare for and relieve storm damage before extreme weather occurs. Climate experts and engineers have created a new model to predict the damage caused by extreme weather. This new framework for “consequence forecasting” enables first responders to effectively target resources before an extreme weather event comes, such as Storm Eunice.

The pre-event decision-making model works by first developing relationships between wind speed and faults on the electricity network. The relationships are then used to estimate faults of electricity networks and potential customer interruptions. This model can be used as early as 24 hours before extreme weather events.

Published in the journal Climate Risk Management, the study findings can enable effective first response to manage infrastructure (基础设施) systems smitten by dangerous weather. Having the forecasting tools to predict and prepare for storm damage will reduce the social consequences of extreme weather, including power loss for customers and fines for electrical distribution companies.

Dr Wilkinson said, “Our model has the potential to change the way we manage weather and climate risks to our infrastructure networks. While electricity network operators already prepare extra resources when a storm approaches, predicting how many power lines may be blown down and where these are likely to be located will allow them to better target the necessary resources to more quickly repair any damage. This is likely to become even more important in the future as our changed climate is predicted to produce more frequent and more intense storms and some of these may be beyond the experience of the people tasked to deal with them.”

Study co-author, Professor Hayley Fowler, of Newcastle University’s School of Engineering, added, “This consequence forecasting is so important for planning emergency response in fast-evolving storms like Eunice. Our model could be used to regularly update energy companies and other infrastructure operators on the potential consequences of approaching storms as forecasts are updated in real-time.”

6 . Rain is vital to life on Earth. However, rain isn’t just made of water anymore—it’s partly made of plastic.

Millions of tiny pieces of plastic, called microplastics, are wandering around Earth’s atmosphere and traveling across entire continents, according to a study published in the journal Proceedings of the National Academy of Sciences on April 12. Another study, published in the journal Science in June 2020, has revealed that every year more than 1,000 tons of the particles (颗粒)—equivalent to over 120 million plastic bottles—fall in rain.

Microplastics are plastic particles less than 5 millimeters in diameter (直径) and come from a number of sources. Plastic bags and bottles released into the environment break down into smaller and smaller bits. Some microplastics are manufactured deliberately to provide abrasion (研磨) in a host of products, such as toothpaste and cleansers, according to the Daily Mail. Another major source is your washing machine. When you wash synthetic (合成的) clothing, tiny microfibers get flushed (冲掉) away with the wastewater. Even though the water is treated by a wastewater plant, the microplastics remain, and they are released into the sea, according to American magazine Wired.

Plastic rain may remind people of acid rain, but the former is far more widespread and harder to deal with. The tiny particles, too small to be seen with the naked eye, are collected by the wind from the ground. They are so light that they stay in the air to be blown around the globe. As they climb into the atmosphere, they are thought to act as nuclei (核心) around which water vapor (水蒸气) condenses (凝结) to form clouds. Some of the dust falls back to land in dry conditions, while the rest comes down as rain, according to the Daily Mail.

Microplastics have been found everywhere you can imagine. From fish and frogs to mice and mosquitoes, their bodies have been found, on average, to contain 40 pieces of microplastic, reported Daily Mail. As the top of the food chain, humans are exposed to microplastics, too. “We live on a ball inside a bubble,” microplastic researcher Steve Allen at University of Strathclyde, Scotland, told Wired. “There are no borders, there are no edges. It (plastic rain) raining on the land and then getting blown back up into the air again, to move somewhere else. There’s no stopping it once it’s out.”

7 . Coming upon a clear - cut in an old forest is a shocking experience. Tees large and small are collapsed one above the other in pile, and the ground is covered with the tracks of heavy machinery. Such was the scene when forest activist Zack Porter and I hiked a newly built logging (伐木) road in Green Mountain National Forest.

Clear - cutting in the American forests has long been widespread. But now, the Forest Habitat Creation Project represents new reasoning which is hotly debated - that clear - cutting benefits native creatures. The thinking is that clear - cutting done wisely can mimic natural disturbances, for example, from insect invasions or from storms overturning older trees that produce what ecologists call Early Successional Habitats - places where young trees and bushes get the upper hand and animals that depend on such habitat thrive.

The project also states that forests “can only be saved by being destroyed” - by keeping them young. Timber (木材) interests are enthusiastic about the approach because it lets them profit from cutting trees while claiming the significance of conservation. Hunting groups favor it because a younger, less thick forest makes it easier to find the game and birds they're tracking.

Nevertheless, Porter says, “Allowing some of the oldest standing trees in New England to be removed is equal to dereliction of duty on the part of the government, who sees the forests as commodities (商品).” “Forests can produce clean water, clean air, carbon storage, and biodiversity that we need,” he continues as we walk among lovely mixed hardwoods and evergreens that are cut down for logging. “We shouldn't be removing them for short - term gain.”

In this sense, Zack Porter's description of logging for wildlife for short - term gain - the short - term gain of favoring habitat for species people today want to see and hunt - is reasonable.

8 . “What if we treat the ocean as if our lives depend on it? Or, what if we don’t?” World-famous marine biologist Sylvia Earle poses her famous “what if” questions to inspire people to reflect on how they can help save the ocean. In 1998, Time magazine named Earle its first “Hero for the Planet.”

Earle’s move to Florida’s west coast at age 12 is what started a lifelong passion. She says, “That’s where I first fell in love with the ocean.” In 1953, using newly developed equipment, the young scientist became one of the first in her field to scuba dive (水肺潜水). Her first long-term exposure to the ocean depths came in 1970 when she led an all-female research team to study the ocean. They lived under the sea in a submersible (潜水器) for two weeks. When they returned to the surface, world-wide cheer and praise were waiting, especially for Dr. Earle.

Sylvia Earle’s career includes many firsts. In 1979 she became the first woman to walk the ocean floor 381 meters below the surface. In 1990, she became the first female chief scientist of the U.S. National Oceanic and Atmospheric Administration (NOAA).

Through the years, Earle has spent roughly 7,500 hours underwater. During that time, she has become increasingly alarmed by the significant changes she has observed.

The famous scientist fears that the ocean is dying. Climate change, overfishing, the dumping of trash and chemicals and oil spills are just some of the many causes. In order to tackle the problem, Earle formed Mission Blue in 2009. This organization promotes the legal protection and conservation of the world’s oceans. Her plan is to develop “Hope Spots,” protected areas large enough to reverse (逆转) damage and restore the ocean.

For those consuming Asian food, using chopsticks     1    (be) almost second nature. About 20 to 33 percent of people in the world use chopsticks     2     a daily basis. Not all of those are disposable (一次性的),     3     no doubt many are.

Felix Böck, a student at the University of British Columbia, was eager to find a way to recycle wood from construction projects, and he had a particular interest in bamboo. One day he found a drawer in his friend’s house     4    (fill) with disposable bamboo chopsticks, and an idea hit him.

He decided to give     5     second life to disposable chopsticks by making them into home     6    (decoration) or other accessories (配件). He told the idea to restaurant owners,     7    (convince) them to install recycling bins in their restaurants. He cleaned the chopsticks, pressed them into square pieces and coated them with glue. The square pieces were then     8    (creative) arranged into household and office products. Böck’s company, called Chop Value, has repurposed chopsticks into desktops, cutting boards and even table games.

Since 2016 when the company     9    (found), Chop Value has rescued billions of chopsticks from landfills. Instead of an economy of the typical take-make-dispose model, Chop Value seeks to create one     10     transforms waste into a usable resource.

10 . If you’re not at least a bit terrified by the climate and ecological breakdown unfolding before our eyes, you haven’t grasped the scale of the crisis. Eco-anxiety, defined as “a chronic(长期的)fear of environmental doom”, is on the rise. But redirecting this anxiety into anger and collective action might just pull humanity back from the brink.

We don’t yet know how deeply eco-anxiety affects people, but we can learn not to repeat the mistakes of long-gone societies lost to environmental collapse. Jared Diamond’s Collapse: How Societies Choose to Fail or Succeed uncovers the common driver that led to the fall of ancient civilizations such as the Central American Mayan, the remote Pacific Easter Island, and the Mycenae: People accidentally destroyed the environmental resources on which their societies depended.

Today, we are living in a new climate and ecological age. The new normal is one that humans have never before experienced on earth, and that has occurred within a single generation. We can’t claim ignorance. Numerous scientific reports show: unprecedented(空前的)wildfires in the Arctic, heatwaves annually breaking records, the Amazon shrinking and drying, and species extinction rates accelerating. Nature’s dangerous decline is unprecedented.

So, it’s not surprising that eco-anxiety is on the rise. Anxiety is often a private emotional state: We feel alone, stuck inside our own heads, and our emotions stop us from doing the things we want. But anger, directed appropriately, can fuel powerful collective action for change.

We are on a pathway to destroy the global conditions for human survival. Unlike previous civilizations, we have the science and technology to understand our danger and chart a new pathway. This is a moment for all of us to channel our eco-anxiety, fear and anger into energy for change.
