2 . Styrofoam, or polystyrene, is a light-weight material, about 95 percent air, with very good insulation (隔热) properties, according to Earthsource. org. It is used in products from cups that keep your drinks hot or cold to packaging material that protects items during shipping. With the above good features, Styrofoam still enjoys a bad reputation. It cannot be recycled without releasing dangerous pollution into the air. The U. S. Environmental Protection Agency says it is the fifth-largest creator of harmful waste.
But now the common worms which are usually disgusting can come to the rescue, specifically, meal-worms. Scientists from the U. S. and China have discovered that meal-worms can digest plastic. One meal-worm can digest a pill-sized amount of plastic a day. Study co-author Wei-Min Wu says that in 24 hours, the plastic is turned into carbon dioxide.
Since Styrofoam has no nutrition at all, are the worms hurt by eating plastic? Much to the scientists’ surprise, the study found that worms eating Styrofoam were as healthy as worms eating bran (谷糠) . The researchers will study the worm’s eating habits and digesting system, looking to copy the plastic breakdown but on a larger scale. Once the way can be put into practice, it will make a revolutionary difference to the disposal of plastic.
“Solving the issue of plastic pollution is important”, says Wu, a Stanford University environmental engineering instructor. After all, our earth is small and landfill space-is becoming limited with too much garbage waiting to be dealt with, he says.
About 33-million tons of plastic are thrown away in the United States every year. Plastic plates, cups and containers take up 25 percent to 30 percent of space in America’s landfills. One Styrofoam cup takes more than 1 million years to recycle in a landfill, according to Cleveland State University.

3 . When thinking about what you can do to help the planet, do you support regenerative (再生) agriculture? Do you even know what it means? While it sounds like something that is up to farmers, there are ways that the rest of us can support it; one way is to practice soil-friendly eating.
Eat a variety of foods
A group of different foods can be good for getting a variety of nutrients, and by eating different types of foods, you’ll help create demand for a wide variety of agricultural products, which is better for soil.
Embrace the pulses (豆类)
The pulses are cheap and great alternative to meat.
Make sure meat is sustainably produced
Reduce food waste
Reducing food waste has been getting much attention recently. By some accounts, it is one of the most important things we can do to fight the climate.
A.We generally recommend eating less meat or none at all |
B.It also helps ease the strain on soil since it reduces its workload |

6 . It’s been more than 60 years since Jane Goodall started her pioneering work. In 1960, she was chosen to go to what is now Tanzania and study the little-known world of chimpanzees. Since then, Goodall has received many awards and honorary degrees as a world-famous conservationist (自然环境保护主义者). Now, Goodall has received an unusual honor. She is becoming a toy — a Barbie doll.
Goodall may not have expected to become a Barbie at 88 years old — but it’s not just any doll, it’s made out of recycled plastic. And Barbie is partnering with the Jane Goodall Foundation and its Roots & Shoots program which inspires young people to protect animals and the environment.
“You know, the main message is that every day you live, you make an influence on the planet and you get to choose what sort of influence you make,” Goodall said.
“There was a little boy of 7 in Burundi, and I had given a talk to the school and he came up to me and said, ‘If I pick out a piece of trash every day, it will make a difference, won’t it?’ And I said, ‘Yes it will. And suppose you persuade (劝说) 10 of your friends to pick up a piece of rubbish every day.’ He said, ‘Oh, that would really make a difference and then they could all get 10 of their friends, couldn’t they?’ Goodall said, “So, that’s it. The cumulative (积累的) effect of small actions can lead to big change.”
She’s been inspiring young people for decades, but now, newer generations will get to know Jane Goodall. “I sincerely hope that it will help to create more interest in the natural world,” she said about the Barbie. “Because hopefully, you know, they’ll learn more about me through the doll. And that will get them interested. It doesn’t really matter if they have a career in conservation, as long as they pay attention to conservation in their daily lives.”

7 . Ways to Save the Ocean
It’s no doubt that the ocean needs our help.
Still, however much we understand that reducing and recycling is not enough, small actions can help us save the ocean. With this in mind, we’ve rounded up some simple actions we can all take to save the ocean.
Commit to a plastic-free lifestyle. So, in order to help save the ocean, many people are committing to a plastic-free lifestyle. The United Nations (UN) has even encouraged the public to think about how they deal with plastic and the ways they can live without it, or replace it:
Turn your food waste into compost (混合肥料). Composting food waste is an easy way to reduce methane (甲烷). Not only does compost reduce methane production, it can also help you fertilize your personal garden.
A.Reduce your carbon footprints. |
B.Use those reusable things in your daily life. |
C.And try decreasing your food waste by shopping locally |
D.Just remember: the fight for saving the ocean doesn’t end here. |
E.Of course, there are many other essential organizations in the world. |
F.It's likely that a lot of your self-care products contain damaging materials. |
G.The best thing that you can do for the ocean is to join a movement to save it. |

9 . They say once you learn to ride a bike, you never forget. Most of us learned to ride when we were kids, and many still wear our helmets, put our feet on the pedals, and shoot off for a ride on the streets. In recent times, cycling has seen an increase in popularity, so many people raise a question:
First, let’s look at the health benefits. Cycling can improve your cardiovascular (心血管的) health and burn extra body fat. Strengthening your muscles in your legs helps increase your potential torque (扭矩) and cadence (节奏).
Cycling can be a great way to go to work or get about town.
So, whether people want to cycle for their health, their wallet, the environment, or a combination of all of them —the popularity of cycling is on the rise.
A.What makes cycling so convenient? |
B.But cyclists face neither of these issues. |
C.And people will choose to go to work by cycling. |
D.This can save you a lot of money on fuel or public transportation. |
E.Finally, cycling can also be good for the environment. |
F.And the benefits from cycling aren’t just physical, but mental as well. |
G.What makes it so attractive for people to take their bikes once again? |
10 . Levon Biss was looking at insects from his garden through a microscope he bought for his son. For fun, they unintentionally placed an insect under the lens (镜片). “It is amazingly beautiful!” they both screamed.
The father had been making a career taking photographs for advertisements. But that experience gave him a new direction. Around the world, insect populations are in decline because of habitat loss and climate change. Biss thought that if people could see what he saw through his son’s microscope, they would care more about protecting insects.
So Biss turned to macrophotography: taking close-up pictures of small things, like flowers or bugs. His work has attracted attention not just for its unusual beauty. It also raises awareness about the need for conservation.
In 2016, Biss showed his first insect project, Microsculpture. The term refers to the features of an insect’s exoskeleton, or outer shell, which develops over time as the bug adapts to its environment.
Biss’s pictures capture the insects in all their microscopic details. Then he blows up the images until the insects become larger than life, some of them eight feet tall. But each image takes weeks to make. He uses a digital camera with a microscope lens. The camera is fixed on a computerized track, which allows Biss to take a shot, then move the camera by seven microns (微米) — a distance equals to about 1/10 the thickness of a human hair — for the next shot. In the end, Biss might take 10,000 shots of a bug. A computer combines these small pictures into a single image.
Biss’s latest exhibition is Extinct and Endangered at the American Museum of Natural History. He selected bugs that were extinct or endangered, hoping his photographs would serve as a better purpose. “I communicate visually,” he says, “The way I work is through pictures. But I think it’s my duty to shake things up and get people to pay attention.”
