2 . Western Australia may soon be home to the world’s tallest wooden building, after authorities plans for a 191.2-meter-tall tower constructed using mass wood. Perth’s Metro Inner-South Joint Development Assessment Panel (JDAP) approved the developer Grange Development’s proposal for the tall building.

The tall building, currently named the C6 building, would stand nearly twice as high as the current record holder. The developers say 42% of the building will be constructed from wood, with the columns and core made of concrete (混凝土). If completed, the high-rise will go beyond the current world’s tallest wooden building, the Ascent tower in Wisconsin, America, which stands at 25 stories or 86 meters. The structure, located in South Perth, Australia, will also be taller than the coming wood Atlassian Headquarters in Sydney, which is expected to claim the record from Ascent but is yet to be completed.

Like Atlassian Headquarters, the C6 building will combine wood beams (横梁) with a steel supporting structure to support the whole structure. According to Grange Development, the 50-story building will contain more than 200 apartments.

It will be Western Australia’s first carbon-negative residential building. Grange Development’s director, James Dibble, said, “Our desire with the building is to shift the focus towards a more climate-conscious approach.” The building will use 7,400 cubic meters of wood harvested from 600 trees. “We can’t grow concrete,” Dibble said, calling the plan “a new open sourced blueprint that uses construction methods to balance out the CO₂ within our built environment, which is the single biggest trigger to climate issues”. “This is our opportunity to show that we genuinely care about the climate crisis we are doing very little about as an industry,” he added.

Philip Oldfield, head of the University of New South Wales’ School of Built Environment, said, “Typically we build tall buildings out of steel and concrete, Concrete is responsible for 8% of all CO release. So by replacing concrete and steel with a biological material such as wood, it is going to reduce the environmental impact of the building quite significantly.”

3 . The UK typically produces an additional 30% of rubbish throughout the festive period compared to the rest of the year, as Britons collectively send over 100 million bags of rubbish to landfills every Christmas.     1    .

Remember that less is more. Research from Business Waste found that UK citizens spend £700 million on unwanted gifts every year. In addition, of all the purchases made for Christmas, only 1% will remain in use six months down the line.     2    . Furthermore, try to choose products with minimal packaging and recycled materials wherever possible. Simple switches can make a big difference!

    3    . If you’re searching for a gift that does as good as it looks, step inside the Ocean Bottle Christmas Gift Shop. There’s something for everyone, including the planet. When you buy an Ocean Bottle, you fund the collection of one thousand ocean-bound plastic bottles before they enter the ocean. Besides, 67% of these award-winning bottles are recycled.     4    . So, you can rest assured that they won’t end up in the landfill before next Christmas!

You need to know the materials.     5    , it can be easy to forget about other things like wrapping paper or our clothing. For example, some cards and wrapping paper are finished with materials that can’t be recycled. So, from Christmas cards to your Christmas sweater, take the time to look at materials and understand if and how you can deal with them in the most planet-friendly way. Reusing old wrapping paper or purchasing recyclable paper is highly recommended.

5 . A powerful earthquake hit Morocco, killing thousands of people and causing huge damage over a large area.

The earthquake struck around 11 pm on Friday night. It was not only one of the most powerful earthquakes ever recorded in Morocco, but also the country’s deadliest earthquake in over 60 years. So far, the earthquake is reported to have killed over 2,900 people. The earthquake was especially precarious as it happened at night, when most people were asleep at home.

The center of the earthquake was in the Atlas Mountains, about 72 kilometers southwest of Marrakesh, a large city popular with tourists in the center of Morocco. Fortunately, many of its modern buildings survived the earthquake. However, the old part of the city, called the Medina, whose buildings are over 1,000 years old, was hit hard, leaving many of those buildings in ruins.

Outside of Marrakesh, the earthquake caused even more damage. In the Atlas Mountains, the earthquake’s center, there were many small villages. Many people in the area lived in simple houses made of mud, a traditional way of building in Morocco. But they’ re not strong enough to survive earthquakes and many of these houses simply fell apart, turning into sand. The Moroccan government has laws requiring buildings to be built more safely, yet these rules were often overlooked.

In larger cities, rescue efforts seemed to be going well. But it took a lot longer for help to reach remote (偏远的) areas in the mountains. That meant the local people in those areas had to deal with the situation on their own. They had to dig through the ruins with their hands, searching for survivors who were trapped. Moreover, many people were sleeping outside, unsure if their houses were safe enough.

More help was on the way. Many outside countries offered teams of experts and emergency supplies. But the government said too many different rescue teams could make the situation more confusing.

6 . As newer, more advanced technologies come out, huge amounts of electronics (电子产品) are thrown away, instead of being reused. These goods often end up in landfills, where the chemicals inside them may be a danger to the environment. Electronics can contain harmful materials. If these materials get into the ground or water, the pollution can cause serious problems. Most electronics require metals. These metals must be mined from the Earth. Often the mining process creates serious pollution.

A group known as Waste Electrical and Electronic Equipment (WEEE) Forum is trying to make people more aware of the problems of e-waste. Recently, the WEEE Forum asked researchers from the United Nations (UN) to study a kind of e-waste that’s often not noticed because people don’t consider the goods to be electronics. The WEEE Forum calls this kind “unable-to-be-seen” e-waste.

The UN study shows that about 1/6 of all e-waste is “unable-to-be-seen”. Though it’s “unable-to-be-seen”, it’s certainly not a small amount. The “unable-to-be-seen” e-waste weighs about 9 billion kilograms. The WEEE Forum says that if this e-waste were put into 40-ton trucks and the trucks were then lined up, the line of trucks would be about 5,630 kilometers long.

The surprising kind leading the “unable-to-be-seen” e-waste group was toys. Worldwide, roughly 7.3 billion electronic toys are thrown away each year. These include goods like car racing sets, electric trains, and musical toys. They also include toys with electronic parts, like dolls that speak or games with electronic timers. In all, toys make up about 35% of “unable-to-be-seen” e-waste. But the problem is far larger than just toys. The report also shows that other everyday goods like home alarms, smoke alarms, power tools, and computer cables (电缆) are also big sources of “unable-to-be-seen” e-waste.

The WEEE Forum is hoping that as more people and governments become aware of e-waste, they will make a much greater effort to make sure electronics get reused.

7 . In the U. S., people eat more protein than they need to, which might not be bad for human health, but does pose a problem for the country’s waterways. The nation’s wastewater is loaded with the leftovers from protein digestion: nitrogen compounds(氯化合物) that can feed harmful algal blooms(藻华) and pollute the air and drinking water.

Maya Almaraz, a biogeochemist at the University of California, Davis, and her team wanted to see how much of this nitrogen entered into the U. S. wastewater system because of a protein-heavy diet. The researchers found that the majority of nitrogen pollution present in wastewater—some 67 to 100 precent—is a by-product of water people consume.

Once it enters the environment, the nitrogen can have a series of ecological impacts. It helps algae grow much faster than they would normally, which is harmful to humans, other animals and plants. And when the algae eventually die, the problem is not over. Microorganisms(微生物) that feed on dead algae use up the oxygen in the water, leading to “dead zones,” where many species simply cannot survive, in rivers, lakes and oceans.

Although it is possible to treat algal blooms, many of the current methods are not always effective at getting rid of all of the harmful growth. Some of these methods can even lead to additional pollution. So the best strategy for dealing with the effects of nitrogen pollution is prevention, says Patricia Glibert, an ocean scientist at the University of Maryland. Almaraz and her team suggest that controlling nitrogen pollution could be approached more quickly with a change in eating habits that could save billions of dollars in the long term.

8 . Micro plastics can accumulate in the brains of mammals (哺乳动物) and even lead to behavioral changes,   according to a new study. This not only adds to evidence about the harm that micro plastics are doing to our environment, but crucially provides new insight into what they could be doing to our bodies.

Plastic pollution is a huge environmental concern. In particular, tiny pieces of micro plastic have been found everywhere from our oceans to the atmosphere. A team led by University of Rhode Island professor Jaime Ross wanted to learn about whether these micro plastics accumulate in the brains of mammals and the potential impact on behavior.

The researchers gave mice drinking water contaminated (污染) with different concentrations of micro plastics over a three-week period. They used mice of different ages to see whether the effects would vary in the younger or older mice.

Besides indications of changes in the mice’s brains, the team saw changes in their behavior, which were particularly apparent in the older animals. The behavioral changes are similar to symptoms you might expect to see in patients with dementia (痴呆) .

“These were not high doses of micro plastics, but in only a short period of time, we saw these changes,” Ross said in a statement.

“In this study, the micro plastics were delivered orally via drinking water, detection in tissues such as the gastrointestinal tract, which is a major part of the digestive system, was always probable,” Ross explained. “But the brain is protected by a boundary called the blood-brain barrier, which should make it harder to access. The team found that micro plastics had entered the brain’s tissues.”

“Once inside, micro plastics cause a decrease in the levels of a brain protein called GFAP,” Ross said. “A decrease in GFAP has been associated with early stages of some neurodegenerative diseases, including dementia and depression.”

Now that even the remotest parts of our planet are seemingly unable to escape contamination with micro plastics, more research like this, which seeks to better understand how human beings’ plastic habit could be coming back to bite us, is more urgently needed than ever.
