Helen and her family moved to a new location in the city. Helen was excited because most of her friends lived in the same street.
It was the first morning in their new house. She woke up early that day and went out on her balcony (阳台). She was expecting wonderful, lovely birds and beautiful greenery with fresh air, but instead it was the complete opposite. There was garbage right outside their front gate. There were no trees and instead of the sweet chirping (鸟叫声) of birds, there were annoying g traffic noises. Helen was angry. “What is this? Why can’t someone do anything about it?” she thought. She went inside the living room. She sat at the dining table, thinking about what she could do about the pollution in her locality.
The next day at school, she went into her class and asked loudly, “Who’s fed up with stinking garbage?” This caught many students’ attention. “Who’s fed up with air pollution and the diseases spread by it?” This time many students answered, “Me!” Helen smiled and then said, “We must clean our surroundings. So help me get rid of the garbage. Help me pick it up! That’s the best thing we can do. We will all go to other classes and ask if they want to join us. I am sure as long as we work together, our community will become a better place!”
In the break time, they all went to other classes, and by the end of the school day, Helen had gathered almost 25 students ready to help her. The day before cleaning, the students took out their pocket money and bought garbage bags, masks and gloves.

Traditionally, profiting from forests often meant capitalizing on timber (木材) —choosing commercial timber. Yet increasingly, there is an understanding that it’s of greater significance to keep trees standing than cut them down for financial profit. Money is not everything. We have to recognize real and lasting value is from natural resources. But money is a fact of life.
Good news is that we can expect entire natural woodland is left undamaged and still provides a revenue (收益) stream. Leaving woodland complete does not necessarily mean that we do not touch it at all. Conservation work may involve building back biodiversity or the removal of foreign plant species.
A healthy woodland system can provide a range of yields (产物). Besides eatable yields—top fruit, berries, and food crops, it produces substances for chemical use. The non-timber forest products provided by natural ecosystems vary significantly depending on where they are. But there are always more ways to explore to acquire revenue.
A project in the UK, for example, shows woodland itself is also a draw for visitors. It engages a community who creates a sustainable area of woodland. The community largely obtains revenue by opening up parts of the natural woodland to the public with an adventure playground and outdoor recreational activities on the site. It also offers courses on nest building, special wildlife events and more. The project is thought to have great uniqueness. It centers round the existing natural land; the yields that woodland provides become by products.
Recreational activities, tours, and classes are just the commencement. A rich and bio-diverse woodland can be an ecosystem that draws in more people looking for a beautiful place to stay. Woodland has great value in ecological and social terms. And when you nurse it, it could also add to the income from your land.

4 . Lithium (锂) is called “white gold” for good reason. The metal’s value has been growing rapidly over the last several years, mainly because it is an essential material of lithium-ion batteries, which play an important part in several key sustainable technologies, e. g. electric cars.
As ocean waves, wind and solar power have grown into major players in the energy industry, lithium has also become key to building a future free of petrol. But getting lithium comes at a huge cost. As with most metals, its mining is damaging. It often works like this: Briny water, containing lithium and other metals, is pumped to the surface from underground. Then it sits in pools to allow the water to evaporate, leaving the rest behind as poisonous matter. Workers use chemical reactions to remove the lithium from that, making it into powder which is then packaged and shipped to the buyers around the world. Any accident that releases mine matter into surrounding communities or the groundwater supply could have damaging long-term impacts.
Indigenous (原住民) communities often bear the result of the damage, and political leaders have paid little attention to their concerns. In Arizona, for example, an expanding lithium mine is threatening the Hualapai Tribe’s historical sites. And for politicians who have promised to work with native peoples to deal with it, mining lithium and other precious metals is putting them into a dilemma: How do you ensure the availability of materials which are essential to the future while protecting indigenous people’ rights?
Mining of the metal is expected to increase greatly in coming years. Over time, that will make electric cars inexpensive and, therefore, more popular.
As environmentally conscious consumers buy electric cars in ever-greater numbers, it’s important to be aware of the dirty process that powers those clean air vehicles.

5 . While it throws out about 90 pounds of food per person every year, Japan doesn’t rank at the top of the world’s list of wasteful nations. Still, what’s thrown away represents a serious problem for an island nation with limited landfill space and a goal of greater sustainability. Reinvention can offer an alternative. A Japanese company is taking vegetable peels, cooking oil and other used foodstuffs and making entirely different products.
Concrete is the most widely used construction material in the world, and its key element, cement, is a major polluter of greenhouse emissions. So what if a more sustainable alterative were possible by making cement with food waste, which also would help reduce greenhouse emissions from landfills where that waste would otherwise be thrown away? That’s the idea behind Fabula, a Tokyo-based start-up.
Researchers at Fabula created a recipe to make food concrete by drying leftovers and pressing them into a mold (模具) at a high temperature. The company, founded by researchers at the University of Tokyo, began with items commonly thrown away like cabbage and orange peels but found that almost any food item can be used. It now takes mostly coffee grounds and tea leaves to make its cement. The product’s durability depends on the components.
Fabula is currently producing made-to-order household items, such as coasters and dishes, while awaiting its patent. The goal is to make furniture and larger structures once the technology is able to make the cement more durable. Food production companies that can’t avoid generating waste during their processes have reached out to work with the company. “We hope to become a matching service between companies that have food waste and companies who want to build things out of such materials,” said Takuma Oishi, Fabula’s chief commercial officer.
Since the cement is 100 percent eatable, it could create opportunities during disaster response when temporary structures need to be built quickly. The people inside might even turn to them for food. If the technology advances enough, Oishi suggested, someday we may be able “to eat the homes or furniture when necessary”.

7 . A method to transform a commonly thrown-away plastic to a resin (树脂) used in 3D printing could allow for making better use of plastic waste. A team of Washington State University researchers developed a simple and efficient way to transform polylactic acid (PLA)(聚乳酸), a bio-based plastic used in products such as filament, plastic silverware and food packaging to a high-quality resin.
“We found a way to immediately turn this into something that’s stronger and better, and we hope that will provide people the inspiration to upcycle this stuff instead of just throw it away,” said Yu-Chung Chang, a postdoctoral researcher in the WSU School of Mechanical and Materials Engineering and a co-corresponding author on the work. “We made stronger materials just straight out of trash. We believe this could be a great opportunity.”
Although it’s bio-based, PLA, which is categorized as a number 7 plastic, doesn’t break down easily. It can float in fresh or salt water for a year without degrading (降解). It is also rarely recycled because like many plastics, when it’s melted down and re-formed, it doesn’t perform as well as the original version and becomes less valuable.
“It’s biodegradable and compostable, but once you look into it, it turns out that it can take up to 100 years for it to rot away in a landfill,” Chang said. “In reality, it still creates a lot of pollution. We want to make sure that when we do start producing PLA on the milliontons scale, we will know how to deal with it.”
While the researchers focused on PLA for the study, they hope to apply the work to poly-ethylene terephthalate (PET) (涤纶树脂), which is more common than PLA and has a similar chemical structure and presents a bigger waste problem. They have filed a temporary patent and are working to further optimize (优化) the process. The researchers are also looking into other applications for the upcycling method.

10 . You can see a sea turtle named Hermanan octopus(章鱼) called Octavia, and a seal named Lidia at the Smithsonians National Zoo in Washington DC. Rather than real animals, they are actually artworks made out of plastic trash from the ocean.
These artworks are part of a traveling exhibit called “Washed Ashore: Art to Save the Sea”. The Washed Ashore project, led by the artist called Pozzi, works to raise awareness about plastic pollution in Earth’s oceans.
More than 315 billion pounds of plastic litter the world’s oceans today. Most of the plastic is garbage from towns and cities, as well as trash that people leave on beaches. Rainwater, winds, and high tides bring the trash into the ocean or into rivers that lead to the ocean. Once it is under the waves, the plastic begins to break up into smaller and smaller pieces.
Thousands of sea animals die each year from eating plastic bags and other things. Each year, millions more pounds of plastic end up in the ocean. A recent study found that if that continues, by 2050 the total weight of plastic will be more than that of all the fish in the ocean.
The Washed Ashore project is working to stop that from happening. Since 2010, Washed Ashore volunteers have collected 38000 pounds of plastic trash from more than 300 miles of beaches. They helped Pozzi create more than 60 artworks of sea creatures harmed by plastic pollution.
“These artworks are a powerful reminder of our personal role and global responsibility in preserving biodiversity(生物多样性)on land and in the sea,” says Dennis Kelly, director of the National Zoo.
