2 . Students at St. Stanislaus High School in Mississippi are among the volunteers along US coasts raising oysters (牡蛎) to help restore, or repair weakened reefs (礁). Oyster reefs are an important part of coastal environments. Each oyster cleans 95 to 190 liters of water a day. The reefs provide living space for shrimp, crabs and fish. They also protect coastlines. In the states of Maryland, Virginia, Mississippi, and Alabama, now there are more than 1,000 oyster gardens. Most of them are in wire cages hanging from private ports.

Colin Wood, one student looking after the St. Stanislaus garden, said he was excited by the hands-on work. “I didn’t realize oysters had a big influence on the environment. And 50,000 to 55,000 adult oysters grown here each year go to reefs in Mobile Bay,” he said.

In the 1950s, an average of 37,400 tons of oysters were taken yearly from partly salty waters in the US. But US oyster harvests fell sharply in the 1990s. Data showed the cause of the drop could be overharvesting, pollution, pests and other problems. Then oyster gardening started.

Oyster gardening uses many of the same methods as farming. Farmers around the country grow oysters near the surface of water. Oysters develop much faster where the water holds more food they eat and enemies can be more easily removed. But the oysters are not being grown to be eaten. Oyster gardens get pulled from the water every seven to ten days. The time out of the water is used to clear out small animals, keep oysters from growing through the wires, and dry and clean off plant-life growing on the wires.

Bob Stokes, the director of the Galveston Bay Foundation in Texas, says, “Oyster gardening is as much about education as it is restoration.”

4 . As we all know, waste is extremely bad for the environment. Let’s talk about why litter is harmful to our streets and towns, our drinking water, and sea animals.

Waste can have a bad influence on our cities. Cleaning up litter costs US taxpayers (纳税人) and businesses $11.5 billion each year.    1     Litter on the streets can cause road accidents with hundreds of deaths because of it. Areas that have more waste have more crime (犯罪). The litter on the streets sends a message that people don’t care about their neighborhood.

    2     The litter we drop on the ground can pollute rivers, lakes, oceans, and other bodies of water. 60%of water pollution is caused by littering. Waste hurts sea animals.     3     You may think that when you litter, “Oh, this is just one piece of litter. It can’t do any harm. But if every person does that, even if it’s only once, there will still be 7.9 billion pieces of litter in our ocean. Over one million sea animals die every year because of waste.    4    

As you can see, waste is harmful in many ways.    5     We need to take action to avoid unnecessary waste, and pick up every piece of waste we see. We should try to make it a habit because if we don’t, the waste problem will become even worse.

6 . The world’s first 3D-printed wood log hive (蜂箱) is a new project developed by the Lacrima Foundation in Edinburgh to reduce the troubling decline of honey bee populations around the world.

The Lacrima Foundation is a charity that is “committed to the conservation and protection of one of the Earth’s most important inhabitant.” The charity teamed up with beekeepers in Europe to work towards a rewilding approach that would offer bees a natural nest habitat and, in turn, create resilience (复原力) among bee communities.

Honey bees are one of the most important pollinators (授粉者), and although they may seem small and insignificant, they are vital for the production of our food — we couldn’t eat without them! However, in recent years, bee populations have been severely impacted by the growing climate emergency and our intensive agriculture practices, including the overuse of pesticides.

With help from local partners, the Foundation created 3D-printed wood log hives, which allow the bees to live in an undisturbed ecosystem where they can carry out their lives. They install these hives in high sections of tree trunks to model natural conditions for the big honey bee populations.

Vince Moucha, chairman of the Lacrima Foundation, said, “Even though there are other people and organisations working in the field of natural beekeeping, the impact, progress and scope of these projects is minimal and slow, due to limited access to resources and clear vision. I am driven by responsibility and decided to act on it due to the urgency and importance of this matter.”

The Foundation will continue to work with beekeepers in the UK, Europe, and the United States to help our bee populations survive and thrive for them and us! Check out the Lacrima Foundation, where you can see their mission and donate to the cause and even get a honey bee gift bracelet in return.

8 . Desertification (沙漠化) is a course that has caused much concern over the past few years — and it’s a major problem for the ancient land of Egypt, where 96% of the country’s land is desert.

So why is it that — if you drove a car 10 miles west of the Suez Canal — you would see a large number of forests outlined against the orange sand and blue sky of the Sahara?

The Serapium Forest is the richest of Egypt’s 36 areas that make up a program to fight desertification by creating sustainably managed commercial forests fed completely by wastewater. The 500-mile forest is only a short distance from the 400, 000 people living in the Egyptian city of Ismailia, who produce millions of tons of wastewater every year.

After a dozen-mile journey to the Serapium Forest, the wastewater is then stored underground where oxygen is fed in to speed up the bacterial purification process. A system of pipes then spreads the wastewater throughout the forest. And human wastewater is still rich in chemicals even after being treated.

The government’s effort, called the National Program for Safe Use of Treated Sewage Water for Afforestation is going a long way toward achieving the country’s goals voiced in the 1992 UN Rio conference on climate change.

The research was supported by ForestFinance, a German company that has already planted near-natural forests in Panama and Vietnam to help those countries with their development and wildlife protection. ForestFinance wants to increase the number of species grown in Serapium by including a forest on the site. That way, the biodiversity (生物多样性) of the commercial forest would be able to support a greater number of species, and hopefully bring in money as well. Although the Serapium Forest faces a lot of difficulties, it’s still growing — a 500-acre green wall to join the others in the world in preventing the sands of the world’s deserts from spreading.

China is emerging as a global leader in aviation (航空) decarbonization (脱碳), according to industry experts. This development is     1     result of the scale of the country’s aviation market and     2     (it) new technologies and policies aimed at reducing carbon emissions (排放), they said.

“As the world’s second-largest economy, China     3     (expect) to be the world’s largest aviation market by 2030. We believe China plays an important part in aviation decarbonization with a deep impact on the decarbonization of aviation     4     (global),” said Martin Thomsen, senior vice-president of Air BP, the specialized aviation division of BP, previously     5     (know) as British Petroleum, a London-based multinational.

“We believe that this will lead to an expansion of SAF production,     6     could supply domestic and global markets     7     play a key role in supporting the decarbonization of supply chains,” he said.

Despite current challenges in raw material supplies, technology and policies, China’s SAF industry faces significant opportunities and     8     (have) certain advantages, said Luo Zuoxian, head of intelligence and research at the Sinopec Economics and Development Research Institute.

It will make important     9     (contribution) in reducing carbon emissions in the aviation industry, helping achieve the carbon neutrality (碳中和) goals and     10     (ensure) energy safety in SAF, he said.
