Throughout the world, only 15% of the material that are used to make clothing is properly recycled, according to the Alle SacUrthur Club, an organization in Liverpool, UK, that boosts the circular economy. Most clothing waste—an     1    (estimate) 82 million tonnes from the fashion industry alone-produced every year ends up buried or burnt.

    2    (handle) all that waste, methods to recover and reuse the material are intended as an active response to the future risks by researchers and start-up companies. Much of their focus is on chemical recycling,     3     the material is broken down into its building blocks and applied to create new materials, including fibres that     4     (weave) into new clothes. The challenges lie in     5     (develop) the processes for such treatment. They have to be practical, but they also have to be at least as cost-effective as simply making new fibres.

    6     the natural cellulose fibres from cotton, some other materials include human-made cellulosic fibres. They are derived from wood-pulp cellulose and may be used to produce materials such as viscose (rayon) and a similar material called lyocell.

A change in the manufacturing process is being applied to the textile-waste problem by Essen, a start-up in Seattle, Washington.     7     the company has fundamentally devoted to the process is that it uses discarded textiles, instead of wood, as the source of its cellulose. It has also adjusted the process to produce a fibre that the firm’s co-founder and president Christo Stan says is superior to     8     other cellulosics and cotton, and that can be recycled more times.

Although there are abundant technical challenges, the main barrier     9     widespread textile recycling could be economic, says materials engineer Lijiang Jiang at the Massachusetts Institute of Technology in Atlanta. “Most of the materials are not that invaluable,” Jiang says. So cheap it is to produce polyester, cotton and other fabrics     10     there’s little profit margin unless the recycling processes themselves are very inexpensive.

2 . The San Diego County Water Authority has an unusual plan to use the city’s scenic San Vicente Reservoir (水库) to store solar power so it’s available after sunset. The project could help unlock America’s clean energy future.

Perhaps ten years from now, if all goes smoothly, large underground pipes will connect this lake to a new reservoir, a much smaller one, built in a nearby valley about 1100 feet higher. When the sun is high in the sky, California’s abundant solar power will pump water into that upper reservoir. It’s a way to store the electricity. When the sun goes down and solar power disappears, operators would open a valve (阀门) and the force of 8 million tons of water, falling back downhill through those same pipes, would drive machines capable of producing 500 megawatts of electricity for up to eight hours. That’s enough to power 130, 000 typical homes.

“It’s a water battery!” says Neena Kuzmich, Deputy Director of Engineering for the water authority. She says energy storage facilities like these will be increasingly important as California starts to rely more on energy from wind and solar, which produce electricity on their own schedules, without considering the demands of consumers.

Californians learned this during a heat wave this past summer. “Everybody in the state of California got a text message at 5:30 in the evening to turn off their appliances,” Kuzmich says. The sun was going down, solar generation was disappearing, and the remaining power plants, many of them burning gas, couldn’t keep up with demand. The reminder worked:People stopped using so much power, and the grid (电网) survived.

Yet earlier on that same day, there was so much solar power available that the grid couldn’t take it all. Grid operators turned away more than 2000 megawatt hours of electricity that solar generators could have delivered, enough to power a small city. That electricity was wasted. There was no way to store it for later, when operators desperately needed it.

3 . How to save planet earth

Have you ever held a product in your hands and considered the existential weight of your purchase? Beyond each price tag hides a ripple effect. It expands from soil to water ways, grocery aisle to kitchen plates, factories to fulfillment centers and mail slots to landfills. This global impact has become less hidden in the past decade, and ignoring the people downstream from us has grown increasingly difficult.

We’re more aware than ever of the mark our consumption leaves on planet Earth, which now sustains nearly 8 billion people. Somehow, humans are still pumping more than 30 gig a tons of carbon dioxide(CO₂)per year into the atmosphere, despite the mountain of evidence that CO₂ is the top contributor to greenhouse gases causing global warming.     1    We know we need to do better, but we feel helpless and overwhelmed. Let’s call this the eco-essential crisis; it applies on a deeply personal level for most environmentally aware humans, and on a global scale.

Climate journalist and author Tatiana Schlossberg says even a simple trip to the supermarket can feel paralyzing in 2021. “I want to buy the local thing, but it’s not organic. Or, maybe it’s in a plastic box,” she says. In her 2019 book Inconspicuous Consumption, she ventures way beyond the store aisle and into the web of less apparent ways that humans are damaging Earth. For example, your internet use is tied to extensive carbon emissions and energy consumption.     2     The world is more complicated than that.

In fact, being a good citizen on planet Earth with climate concerns, you’ve likely asked or agonized over this question: What should I do?     3     So, we took this question to five people who have immersed their careers, research and writing in the realities of climate science.

One of their most consistent insights may surprise you: Consumer responsibility misses the mark. “One of the major failings of the environmental movement is having everyone focus on these small things that everyone can do.” says Ayana Elizabeth Johnson-a marine biologist and co-host of the podcast How to Save a Planet.     4     There are just more meaningful and long-lasting ways to expend your energy in the climate fight. Most of them involve organization and collective action.

“Individuals join together to collectively have far more power changing the system than they can as individuals,” says Anthony Leiserowitz, director of the Yale Program on Climate Change Communication.

World leaders at the 5th meeting of the United Nations Environment Assembly (UNEA) agreed that by 2024, they would create and sign a new treaty on plastics. The new treaty would create international laws     1     could help bring plastic waste under control.

Because plastic is useful for so many purposes, it has become a part of nearly all areas of our lives. It’s hard to look anywhere without finding dozens of     2     (object) made of plastic.

The United Nations Environment Program (UNEP) reports that     3     (current) 400 million tons of plastic is produced every year. By 2040, that number is predicted to double. And even though there’s a lot of talk about recycling, only 9% of all the plastic ever     4     ( produce) has been recycled.

Plastic gives off dangerous gases when it’s made and also when it’s burned or buried in the ground. Scientists say plastics are responsible     5     4.5% of the world’s greenhouse gases — the gases that are driving the climate crisis.

Plastic doesn’t “decompose (腐烂)” like natural materials. Instead, it just breaks into smaller and smaller pieces. And as the plastics     6     (fill) our world break down, they create     7     new problem — microplastics.

Microplastics are so tiny that     8     (they) existence is usually ignored. In the past few years, microplastics     9     (find) almost everywhere, from the North pole to Antarctica, from the top of the Earth’s     10     (high) mountain to the deepest point in the sea. They’ve even appeared in the bodies of animals including humans.

Greenhouse gas (GHG) emissions in the Asean (东盟) region are estimated to increase in the same period, based on the latest Nationally determined contributions (NDC) targets up to 2030.

To keep the Paris Agreement temperature goal within reach, Dr Beni Suryadi, Centre for Energy Manager at the Asean Secretariat, stated that ASEAN needs to achieve     1    emissions as soon as possible after 2030 and net-zero GHG emissions as soon as possible after 2050.

However,     2    of the growth in GDP and energy-related CO2 emissions is observed only in a handful of the Asean member states.

“It is vital to reduce energy intensity through lower energy demand and further energy savings and to reduce emission intensity by     3    renewable energy expansion,” he said.

“Current policies need to be enhanced to achieve the NDC targets. The     4    under the NDCs will provide Asean with a better perspective of the need for a more ambitious course of action on mitigation（缓解） in the future. Ambitious energy policies can significantly reduce GHG emission and helps our     5    towards low carbon economies and climate resilient nations.”

Earlier in his presentation, Dr Beni highlighted, “a brief record-breaking drop in climate change – causing carbon emissions during the height of the coronavirus pandemic. However, nowadays we continue to hear the news and read reports that say that global emissions have already     6    to near pre-pandemic levels”.

“While we are grateful to learn that the economy is reviving and we see economic activities taking place everywhere, there is a(n)     7    need for us to limit the growth of emissions. Global GHG emissions continue to rise, at a time when they need to be rapidly falling.”

At the global level, he said, “It is recorded that almost three-quarters of the GHG emissions come from energy use; almost one-fifth from agriculture and land use; and the     8    eight per cent from industry and waste”.

He also noted that the electricity and transport sectors start out as and remain the biggest     9    of GHGs and air pollution in Asean.

“If the Asean member states do what is needed to fully achieve their own national energy efficiency and renewable energy targets, as well as their climate commitments, Asean’s total energy- related GHG emissions in 2040 will be 3,002 MtCO2-eq, 28 per cent lower than in the baseline scenario.

“Power generation remains the largest sectoral contributor, accounting for about 40 per cent and 46 per cent of total GHG emissions from energy in 2025 and 2040,     10    .

“Furthermore, if Asean fulfilled its regional aspirational targets on the energy efficiency and renewable energy, Asean will be able to reduce GHG emissions more sharply to only 2,264 Mt CO2-eq in 2040,” he said.

Public Opinion Counts

Modbury is a typical small town of the south of England with a population of about 1,600. Typical, that is, apart from the fact that there are no plastic carrier bags in the town. None. Plastic bags have been well and truly dumped!

The removal of the plastic bags was the brainchild of Rebecca Hosking, Modbury resident and documentary-maker. Filming a documentary in the Pacific Ocean, Rebecca was horrified at the effects of plastic bags on the wildlife off Hawaii. Among other things, she saw seabirds fatally trapped in plastic bags that don’t biodegrade. When Rebecca returned to her hometown, she discussed this problem with people, including the shopkeepers and everyone supported her suggestion to make the town plastic bag free.

But for Rebecca’s concept, Modbury would still be an unremarkable little place. Now, however, shoppers take re-usable cotton bags shopping with them, or they buy biodegradable corn starch ones on the shops. The shopkeepers now wrap their goods in paper. To prove that the townsfolk are not only committed to reducing plastic waste, they organised a mass beach clean-up last year. Dozens of volunteers came to the beach on the appointed day to clean it up, taking the rubbish that visitors throw away and recycling it. And the greatest part of that rubbish was... no, not plastic bags, but plastic bottles.

Becoming the first town in Europe to ban plastic bags, Modbury is now harvesting the rewards of fame — reporters and camera crews from newspapers and TV channels across the world are coming to this mild town to find out its secret. And, contrary to some of the initial reports, it is a normal town, trying to live life in a slightly different way. As one resident put it. “We’re ordinary people, but we want to make just a little difference.”
