I want to take an action to put my family on the path to zero waste. First, I'll make sure the water in my house won't be left running when no one is using them and the lights in my room will be turned off when I left. Of course, I'll convince my parents to packing the goods in cloth bags instead plastic bags. Beside, I plan to do at least one environmental volunteer project with my family a week. For example, we can spare a few hour on Saturdays to serve at a restaurant but remind diners not to waste food. I'm surely we will be amazed at what much satisfaction we get from our work.
2 . Many people have realized that air pollution can cause damage to people’s health.
How does pollution affect animals？
All animals, whatever their size, can be affected by pollution. Experts agree that pollution affects animals in the same way as it does humans.
Types of air pollution.
Acid Rain (酸雨)—When water drops in clouds combine with acidic air pollutants, the water turns acidic.
Global Warming—The planet is warming due to greenhouses gases, which include carbon dioxide, methane, and water vapor. These gases are released into the atmosphere from air pollution.
You can keep the pets in your home safe from air pollutants by keeping fresh air entering your room and purifying (净化) air with equipment. Unfortunately, this doesn’t protect wildlife, but it’s a step in the right direction to protect your beloved pet’s health. Besides, you should also use less energy, reuse and recycle as much as possible.
| A．How to help protect animals？ |
| B．Useful equipment to protect wildlife. |
| C．Air pollution is a major global concern. |
| D．However, most don’t realize the pollution can affect animals. |
| E．Global Warming impacts the health of both animals and humans. |
| F．Once the water drops down, acid rain causes damage to the environment. |
| G．The pollutants that animals breathe in can be collected in their tissues (组织) over time. |
3 . It should be one of the main goals in today's society to reduce plastic consumption. Though many believe recycling will solve the problem, it's actually the opposite. In 2013,254 million tons of trash was produced in the U.S. alone, and only around 30% was recycled. This means the rest ended up in a landfill and will stay there for up to 1000 years.
Recently, China has stopped importing trash from all over the world. Before this, over 30% of the world's waste would end up in China, causing a popular belief that Asian countries are those responsible for creating the majority of the waste in the world. Now, Asian countries are looking for new ideas to avoid the plastic. One of those ideas was a new, eco-friendly way to pack their goods by avoiding plastic packaging.
One of Perfect Homes Chiangmai's team members, Sam, noticed a creative way to reduce plastic that a supermarket called Rimping Supermarket was using and decided to capture their shelves with his phone. Little did he know that people all around the world would absolutely love this idea. “I just stepped in to get a few items while we were waiting to sign some contracts with our lawyer, who was delayed. I noticed the vegetables wrapped in banana leaves and simply liked the idea. So I took a few pictures and posted them online,” he said. With more than 3.5million views and over 17 thousand shares, the idea becomes something people can encourage more supermarkets to implement.
Some have noticed that not everything on the shelves is completely plastic-free. Many products come to the supermarkets pre-packaged and many companies are interested in wrapping their products in plastic since it is the cheapest and the easiest option. It's now up to the shoppers to show the supermarket which they prefer. If everyone opts for the banana leaf packaging, they will probably stop storing the items in plastic.

4 . I dropped off a bag of my children’s worn-out jeans to a local tailor and when she returned them with brightly colored, patterned patches(补丁) on all the knees, their lives unexpectedly became longer by several more years. Both my kids and I loved those pants, so unique and impossible to buy. This was my first experience with “visible mending”.
Visible mending(VM) is different from traditional mending in that it makes the repair a central point, rather than combining it into the original clothes. There are many reasons for this, from drawing attention to the fact that clothes’ lifetimes have become long and challenging the idea that secondhand clothes are only worn by the poor, to simply adding a personalized touch.
Kate Sekules is a well-known advocate for visible mending. The British-born, Brooklyn-based writer, clothes historian and mending instructor has a new book coming out in September. It is a call to action for clothes lovers of all skill levels to take needles and threads to their beloved clothes. She reassures readers that anyone can do it.
“The skills are easy to pick up: visible mending is for everyone. The only way to go wrong is to say, ‘I can’t. ’It is a skill, but of a modern way. There are many ways to create VM, and there will never be another one like yours. Though you will never sew two mends the same, you will develop a style of your own.”
Sekules spends the first several chapters explaining why practicing visible mending matters so much. She writes about the current fashion industry, and how destructive it is, from the vast quantities of textiles(纺织品) and plastic waste and poisonous runoff poisoning rivers around the world, to the terrible conditions in which clothes workers work. So, rather than waiting around for the companies to clean up their acts, we individuals can effect tiny yet meaningful changes by picking up our needles and threads and wearing our clothes for longer.

5 . On Sept. 21, 2020, scientists announced that Arctic sea ice has already lost two-thirds of its amount over the past four decades. It is part of a shocking trend in polar heating that is already seeing impacts across the globe.
Throughout the spring and summer, Arctic sea ice melted away faster than it usually does, causing the largest loss of Arctic sea ice cover since satellite records began in the 1970s. This year's minimum was reached on September 15, at 3.74 million m² compared with the previous low—4.17 million m²—set in 2007.
What's causing this loss of sea ice? The short answer is our heating climate. A recent study showed that the influence of heat has more than doubled over the past decade or so, which means the melting of nearly a meter thickness of sea ice each year.
The biggest effects of the loss of Arctic sea ice, of course, will be felt locally: from the more possible snowfall to more storms with stronger winds. These will also cause waves as well as rising temperatures. In fact, the increased temperatures transformed northern forests into tinderboxes ready to burn. That melt also means polar bears are losing critical habitat and Inuit hunters are losing ice to preserve their traditions and culture.
On a larger scale, the greatest impact may be the changes in the Arctic 's ability io function as a cooling system for the global ocean. A warmer Arctic will affect the temperature differences between the northern polar region and areas further south. That may, in turn, create stronger heat waves, droughts, floods and potential impacts on farming. And all of us will be more exposed to the disastrous effects of climate breakdown.
We need to hit the reset button right now on how we look after each other and Arctic sea ice to help our planet cope with the climate breakdown.

6 . As heat waves continue to ravage the planet, air conditioners are becoming more and more common. However, these "active" cooling devices are posing problems because the electricity consumption which most people are concerned about and the release of ozone-damaging chemicals worsen the greenhouse gas effect, resulting in the creation of heat islands and further thermal pollution. Therefore, "passive" cooling, which doesn't have such effects, has attracted considerable attention from both scientists and ordinary people in recent years.
In a recent study, a team of researchers from China and US presented an eco-friendly, low-cost smart coating to keep buildings cooler while consuming zero electricity. Infrared radiation-based passive cooling has been investigated since 2014, but challenges, mainly the expensive and unsustainable design, have greatly limited their large-scale and widespread application. Besides, the imbalance in cooling ability of these coatings during the day and night tends to lead to great day-night temperature differences as more heat is lost than gained at night.
The solution therefore requires a "smart" mechanism that can both enhance daytime cooling and minimize nighttime heat loss. To do this, the researchers created a new smart coating comprised of conventional building materials, including titanium dioxide nanoparticles, fluorescent microparticles, and glass microspheres that were engineered to reflect most of the sunlight. Specifically, the titanium dioxide particles effectively reflect sunlight through light scattering（撒播）while the fluorescent particles increase the amount of reflection by changing the absorbed sunlight into fluorescence emissions, which drive more heat away from the building. Meanwhile, the glass microspheres re-send mid-infrared broadband radiation, allowing not only heat loss, but allowing heat exchange to take place between the building and the sky.
The coating was tested on a model concrete building. Through this efficient heat exchange with the sky, daytime cooling was strengthened while nighttime cooling was reduced. The building's inside temperature was always maintained at around 26℃, even when the out-side temperature varied from 24℃ to 37℃ during the day. We believe this new coating will make it to commercialization soon, enabling a sustainable, passive cooling technology that could help to fight climate change and the global energy crisis.

8 . Rather than continue living a comfortable urban life, this British family has sold their London home in favor of launching the world's smallest nature reserve to save a nation's coral reef system. Karolina and Barry Seath— along with their two young daughters—are preparing to move to an island in the Seychelles（非洲塞舌尔群岛） measuring just 1,300 feet long by 980 feet wide（400 by 300 meters）.
They've launched a charity and teamed up with（与.....合作）local biologists in an effort to bring the coral reefs back to life in the smallest African country, which have been almost wiped out by rising sea temperatures. Their land-based coral farm will be only the second of its kind in the world, the other being on Australia's Great Barrier Reef, to specialize in regrowing coral to restore the reefs.
47-year-old Barry, who is a former policeman, said, “We are just a normal husband, wife and two kids, living the sort of life that most others do, but we felt the need to make a positive change for ourselves, our children, and the world we had largely taken for granted.”
Over the course of several vacations to the Seychelles, the Seaths witnessed the gradual deterioration（恶化） of the reefs. "Every time we visited, we noticed the coral was getting worse and worse," said Barry. "All the tourists say the same thing. They love the beaches but are really disappointed with the coral. "
Barry felt it was time to make a change and show his daughters an alternative way of eco-friendly living. He then teamed up with experts at the Marine Conservation Society Seychelles in order to develop the facility. Once it is complete, it will be the first large-scale, land-based coral farm in the Indian Ocean. The eco-warriors hope to use the facility to grow around 10,000 corals per year. Barry said, "Our long-term goal is to show everyone that—with just a relatively small investment—you can have a big positive influence on the marine （海的） environment."

9 . A new study shows that the increased heat from Arctic (北极的)rivers is making sea ice in the Arctic Ocean gradually disappear. The study published this week in Science Advance was led by the Japan Agency for Marine-Earth Science and Technology, together with other scientists in the United States, United Arab Emi rates , Finland and Canada.
According to the research, the main Arctic rivers bring more heat to the Arctic Ocean than they did in 1980. River heat is one of the reasons that cause sea ice loss of the Arctic Ocean. That loss is equal to about 120,000 square miles of 1-mcter thick ice. "If Alaska were covered by 1-meter thick icc. 20% of Alaska would be gone," explained Igor Polyakov, a re- searcher at the University of Alaska Fairbanks' International Arctic Research Center.
Rivers have the greatest influence during spring. The wanning water pours into the ice covered Arctic Ocean and spreads below the ice， slowly destroying it. Once the sea ice melts(融化), the warm water makes the temperature go up. The research found that much more river heat energy entered the air. Since air is mobile, this means river heat can influence areas of the Arctic far from river deltas (三角洲).
The influence was the most prominent in the Siberian Arctic, where several large rivers go into the Arctic Ocean. Canada's Mackenzie River is the only river large enough to contribute to sea ice meh near Alaska, but the state's smaller rivers are also a source of heat.
Polyakov says that rising global air temperatures will continue to warm Arctic rivers in the future. As rivers heat up, more warm water will flow into the Arctic Ocean, melting more sea ice,

10 . The situation of the world’s plants is not good. One fifth of the kinds of plants are in danger of disappearing, according to a report.
“Plants are very vital to human beings,” said Kathy Willis, who led the new report. “Plants provide us with everything—food, fuel, and medicine, and they are very important for our climate controlling. Without plants we would not be here.”
The good news is that deforestation rates around the world have dropped largely since the 1950s. However, this report on the health of plants around the world shows that there is much more to be done.
The report predicts that there are now 390,900 kinds of plants. And about 21 percent of those plants are in danger of disappearing. “The good side is that we’re still discovering lots of new plants, about 2,000 each year,” said Dr. Willis. “The bad side is that we’ve seen a huge change in land cover, mainly caused by cultural activity, with a little bit of climate change in there as well.”
Human activity has a great effect on the danger of plants disappearing. As humans cut down forests to make room for agriculture, towns and cities, biodiversity is lost. This could not only affect our own food supply directly, but also affect the food web.
