1 . Ways to Reduce Plastic Waste

Plastic has been found virtually in everything these days. Your food is packaged in it. Your car, phone and computer are made from it.     1    . While most plastics are advertised as recyclable, the reality is that they’re “downcycled”. 

Luckily, there are simple steps you can take to dramatically decrease the amount of plastic waste you produce.

    2    

One of the easiest ways to keep plastic out of the landfill is to refuse plastic straws. Simply inform your waiter or waitress that you don’t need one, and be sure to state this clearly when ordering at a drive-through. Can’t stand giving up the convenience of plastic straws?     3    . Restaurant workers will be less likely to bring you a plastic one if they see that you’ve brought your own. 

Use reusable bags

About one million plastic bags are used every minute. A single plastic bag can take 1,000 years to degrade(降解). If you’re already bringing reusable bags to the grocery store, you’re on the right track. Purchase some reusable bags and help keep even more plastic out of the landfill. However, you should avoid those bags made from nylon or polyester (聚酯纤维).     4    . 

Use matches

    5    , if you need to light a candle, build a campfire or start a fire for any other reason. These cheap plastic devices can sit in landfills for years and have been even found in dead birds’ stomachs. If you can’t bear to part with your lighter, pick up a refillable metal one to help cut down on waste.

2 . Latin America’s first renewable fuel-powered, trash-trapping wheel is cleaning one of Panama’s dirtiest rivers. A local environmental group led the effort.

The wheel is powered by water and sun energy. It pulls waste out of the Juan Diaz River. Most of the waste comes from the capital area of Panama City, where about 2 million people live. Thousands of kilograms of rubbish flow down the river into the ocean each year.

Robert Getman is the leader of the project. “Cleaning beaches is good,” he said, “but it is more effective and cheaper to trap rubbish in rivers because when it reaches the ocean, the environmental and economic cost becomes too high.”

The environmental group Marea Verde created the wheel, which is named Wanda Diaz, in late September. By the middle of October, Wanda had gathered 28. 6 cubic meters of plastic bottles from the water.

The Juan Diaz River is one of the most polluted in Panama. Waste systems in the area are poor, and land development is not well supervised. The river also passes through Panama City, one of Central America’s largest cities.

Over five years, Marea Verde projects have slowed the spread of rubbish along Panama’s rivers and coastline. Earlier, the group introduced its “Barrier or Trash”technology, a floating device. It caught more than 100 metric tons of waste in the Matias Hernandez River between 2019 and 2020.

“We want to raise awareness that we can prevent the death of this very important river,”said Marea Verde member Sandy Watemberg. She expressed her hope that the wheel will help. But she also pointed to the need for those who use single-use plastics to rethink their behavior. “The most important thing is to achieve a change in habits,” she said.

3 . Windows open? Fans on? Ready for another water break? For schools across Greater Toronto, the extremely hot temperatures provided some lessons in how to beat the heat—or at least attempt to—without air conditioning. It wasn’t easy. With some classroom temperatures getting close to 40℃—one teacher even handed out temperature meters to see how hot it got—both students and educators were red-faced and bathed with sweat all day.

The extreme weather had some parents wondering if their children should be spending most of the day inside hot schools, and a few chose to keep them home. Very few schools across Greater Toronto are air-conditioned. There are no rules or requirements that schools shut down as the temperature rises.

At Bowmore public school, near Coxwell Ave. and Gerrard St. E, teachers arrive at 7 am and open all the doors and windows to circulate fresh air. The windows at the school, replaced in stages over the past few years, swing in at the top, and out at the bottom to provide better air flow.

“Is it hot? Yes. Is it something that makes us feel uncomfortable? Yes,” said Headmaster Lilian Hanson. Despite that, she said she’d never advocate for air conditioners in schools, which are expensive and would consume the city’s electric power. She’d rather see more gardens, more trees—more natural solutions, more sustainable choices.

“We are teaching kids to make good choices,” she said. “Social responsibility is the key.” Students from kindergarten to Grade 8 seek pleasant places under trees and in the outdoor peaceful garden during the break time between classes and after school as the trees there provide much-needed shade. Teachers also take classes with students out there during the day. And kids do get the message about staying cool. Students are reminded to dress in cool clothing. When Hanson arrived at work in a dark-colored dress, a student asked her: “What were you thinking wearing a black dress on a day like today?”

4 . Most of us have heard of the 3Rs: reduce, reuse and recycle. It is the core principle of a sustainable (可持续的) life, but few of us can apply it in our own lives. Now, there’s a “lab” you can explore and discover a way toward living sustainably.

3R Lab is located in Xuhui district, Shanghai. It offers exhibitions, activities and goods that showcase the 3R principle. The key to a sustainable life, according to Vincent T. M. Fong, the 32-year-old from Hong Kong who created the lab, is to make it a long-term promise. “A sustainable life should be sustainable itself in the first place. You can’t lead a sustainable life on a whim. Small and comfortable changes are exactly what you need,” Fong said.

The lab regularly hosts ugly fruit markets, offering these strange fruits which are often thrown away by traditional markets and consumers at a quite attractive price. “They’re thrown away simply because of their appearance. Buying fruit regardless of how they look reduces food waste significantly in our daily life,” Fong commented.

A water tank with two types of straws is another equipment in the lab. “One type is made from normal plastics widely used in our daily life while the other is from PHA, a new replacement for plastics, and the water is sourced from the Suzhou River,” explained Ni Li, an employee of the lab. Visitors can see how the PHA straws degrade (降解) into a thin layer in just one month, while the others remain unchanged.

“Leading a sustainable life does not necessarily mean sacrifice,” said Fong. Consuming ugly fruit and using degradable plastics are small changes that are good for the environment and easy to stick to. Only in this way can the 3R principle become part of our lives, he added.

After working there for six months, Ni, who wasn’t mindful of the 3R principle before arriving at the lab, now uses her cup every time she buys a coffee. “The job has reshaped my life,” Ni said.

As one of the most well-known tourist     1     (attraction) in China's Guangxi Zhuang Autonomous Region, the beautiful Li River was polluted. Water in the river suffered     2     (great) as tourists threw rubbish into the river. Besides, people on the boats     3     (pour) the oil from the kitchens into the water. Also chemicals used to increase crop production resulted     4     poor water quality, causing a decrease in the number of fish species. Luckily, local officials were concerned about the issue and began to take steps     5     (address) it. By     6     (construct) waste water treatment facilities and closing or moving polluting enterprises,     7     water quality was improved. Not only were new rules introduced to preserve the river,     8     the local authorities also used the media to spread environmental     9     (aware) and encourage greater use of clean energy. With these measures, China's waterways are heading towards a clean and     10     (sustain) future.
