Seagrass meadows (海草床) are wonder plants growing beneath the sea. They feed and shelter sea life and are masterful at storing carbon. Thanks to the assistance of tiger sharks, a huge seagrass meadow in the Bahamas Banks has been discovered, offering the world a tool to fight climate change.
Seagrass has usually been detected by Earth-orbiting satellites that identify darker spots in the blue water. In a recent study, tiger sharks were selected as research tools due to their highly consistent associations with seagrass ecosystems. They spent 70% of their time in seagrass meadows. The team equipped eight tiger sharks with satellite labels, seven sharks with camera labels, and used a 360-degree camera on a shark for the first time ever.
The data researchers collected was astonishing. The world’s largest seagrass ecosystem, measuring at least 66,900 square kilometers, has been discovered. This reflects a 41% increase from previous estimates of global seagrass. Seagrass can capture (捕获) huge quantities of carbon by photosynthesis (光合作用) and stores it on the seafloor. In terms of climate change, this is excellent news; seagrass is 35 times faster at removing carbon than tropical rainforests. When referring to global seagrass carbon stock estimates, the study indicates that seagrass in the Bahamas may contain 19.2% to 26.3% of all the carbon stored in seagrass meadows on Earth.
Yet seagrass meadows are rapidly disappearing, with over 92% of meadows in the UK gone, according to the World Wildlife Fund. Scientists are collecting seeds and trying to grow new seagrass meadows through restoration projects. This new discovery offers optimism and proves the importance of the ocean for healing.
The sharks led us to the seagrass ecosystem in the Bahamas, which we now know is likely the most significant blue carbon sink on the planet. What this discovery shows us is that ocean exploration and research are essential for a healthy future. The undeveloped potential of the ocean is limitless. These meadows can be protected and can be copied, offering hope for climate change around the globe.

【推荐1】If you’re looking for something fun to do, pack a picnic dinner and take your family or friends to a beautiful place to eat. However, there’s a wrong trend—viewing picnics as an excuse to transport food in single-use plastic containers. Sure, it means the clean-up is easy at the moment, but it just puts it off to a later point, when it takes the form of the volunteer clean-up and landfill management.
●Use food containers wisely
Using reusable containers is the easiest way to reduce waste.
●
Using washable dishes for a picnic does not require much more work than single-use ones. You’d have to carry the waste out anyway in a trash bag, so why not pack your dirty plates into a bag and put them in the dishwasher at home? If you’re worried about breaking, take some solid camping plates.
●Think about the drinks
Forget the single-use, single-serve drink bottles.
●Put cloth bags to good use
Cloth bags are amazing. I use them for so much more than just buying food at the store. They’re perfect for packing sandwiches, dried or fresh fruit, and other snack foods. You can use them to pack glasses or plates to prevent breaking. They can also work as a napkin, tea towel, or garbage bag if needed.
A.Clean up the waste |
B.Avoid plastic plates |
C.Be sure to add a few to your picnic basket. |
D.There are some healthy dishes you can make or buy. |
E.To prevent this, a plastic-free picnic can be a brilliant idea. |
F.These create a huge amount of waste, which can be easily avoided. |
G.In addition, keep in mind that you don’t have to pre-pack everything. |
【推荐2】Founded in 1998 by Andrzej Adamcio, the company called Anmet was originally started to provide manufacturing companies with solutions for metals recycling. In 2014, Adamcio began to recognize that there was a growing need for solutions, for recycling composite wind turbine blades (复合风力发电机叶片) at the end of their life spans. Using his experience in metals recycling, Adamcio began to work on ways to recycle glass and carbon fiber composite blades, and today, wind blade recycling has become one of Anmet’s main focuses and a major area for growth going forward.
In the long term, Anmet’s recycling solution involves the physical repurposing (赋予新用途)of glass fiber wind turbine blades. The company’s services start on-site: representatives will travel to a wind farm and dismantle the blade into sections, followed by transport of the parts back to the Anmet’s facility for reconstruction into architecture or infrastructure products. There are several environmental advantages to this type of recycling. For example, repurposing blades rather than completely destroying them via burning, breaking them into pieces or other means costs less energy, is less costly and produces less emissions and dust.
The company has filed patents for other infrastructure solutions currently going through testing at Rzeszow University of Technology, including geotechnical blocks (岩土工程砌块) for road slope strengthening. Replacing typical steel or steel-strengthened concrete road barriers with repurposed glass fiber wind blade components enables greater resistance to damage from corrosive(腐蚀性的) soil environments. The blocks can be adapted in shape to fit the needs of a particular situation. So far, Anmet has built and trialed early models of these blocks, and is working toward registering them for construction use within the European Union, with hopes of extending into the U.S. market as well.

【推荐3】Rubbish is a major kind of environmental pollution. Each person produces about two kilograms of rubbish in our homes a day. And this is only a small part of all the rubbish we produce. We also create waste in industry.
Have you wondered what happens to the rubbish? Most of it is buried in landfills (垃圾填埋地) or burned. Less than 25% of our waste is recycled.
A landfill is carefully designed and it is built into or on top of the ground. Rubbish buried in landfills is cut off from the surrounding environment (groundwater, air, rain, etc).
One problem with landfills is that they cover a lot of land space. If they are not well-built, there is a high risk of polluting the land and water. Some people also say that landfills remove materials for ever. As a result, the materials that can be reused are wasted.
Burning rubbish in factories is another way to cut out waste. Burning reduces 95% of the waste. And if poisonous materials are removed, and burning is completed at controlled temperatures, it is possible to do so without causing too much pollution. Some factories could even produce electricity from the burning process.
Not all of the rubbish can be burned, so we have to separate it before we burn it. However, separation costs a lot of money. Another problem with burning rubbish is that what is left after burning is poisonous. How to safely deal with it is a continuing problem.
Before the mid-20th century, landfills were the main way to deal with waste. In the late 20th century, other ways like recycling have been introduced to help reduce global pollution.
Maybe in the near future, with combined efforts, scientists will find a better way to dispose rubbish and cut out waste, like recycling things. But anyway, mountains of rubbish from life every day is a huge burden for any country.

【推荐1】“The pen is more powerful than the sword(剑).” There have been many writers who used their pens to fight things that were wrong. Mrs Harriet Beecher Stowe was one of them.
She was born in the U.S.A. in 1811.One of her books not only made her famous but has been described as one that excited the world, and was helpful in causing a civil war and freeing the enslaved race. The civil war was the American Civil War of 1861, in which the Northern States fought the Southern States and finally won.
This book that shook the world was called Uncle Tom's Cabin. There was time when almost every English-speaking man, woman, and child has read this novel that did so much to stop slavery. Not many people read it today, but it is still very interesting. The book has shown us how a warm-hearted writer can arouse people's sympathies. The author herself had neither been to the Southern States nor been a slave. The Southern Americans were very angry at the book, which they said did not at all represent true state of affairs, but the Northern Americans were wildly excited over it and were so inspired by it that they were ready to go to war to set the slaves free.

Two decades since the founder of Zappos first put forward the idea of selling shoes via the Internet and struggled to convince investors(投资人), e-commerce, or online shopping, has taken over. If there's one thing Zappos has taught us, it's that customer experience matters. The retail giant got ahead by encouraging customers to order multiple sizes of the same product, and then providing a free and easy way to return whatever didn't fit.
Today, chatbots and mobile apps allow online retailers to ensure customer success. Machine learning technologies also provide personalized recommendations based on a user' s search history. And overnight delivery has become commonplace. Even so, some aspects of the in-store experience go missing when shopping in the digital world.
Fortunately, we have live commerce. By combining e-commerce with live streaming, live commerce helps improve participation, bridge the gap between customers and products, drive sales, and, in cases where bidding is involved, increase the average sales price.
This trend controls the market in China. Taobao, the world's biggest e-commerce website, gives the power to farmers, business owners, and self-employed entrepreneurs with consumer-to-consumer live streaming. Successful influencers on Taobao rise to celebrity-like status, helping promote the shopping experience. Beyond just generating fans, top sellers like Li Jiaqi and Weiya bring home serious money
Danielle Bailey, managing vice president of intelligence firm 12 Inc.. once put it, "China used to be thought of as a copycat…but now more western tech and retail leaders are being inspired by the all-channel retail, social commerce, and mobile commerce innovations in China.”
