1 . You might not expect it, but cows are a large source of the greenhouse gases that are driving climate change. Cows produce lots of methane by breaking down the grass, Now scientists have shown that the pollution from cows can be reduced by adding a little seaweed to their food.
Scientists first discovered that seaweed could help control methane from cows several years ago. But this work was done in a laboratory, there were many questions about whether the idea could work in real life.
In the lab studies, the cows were given quite a bit of seaweed, and they would cause losing weight. That wasn't helpful, since cows are often sold by weight. It also wasn't clear if the seaweed would stop working if it was used for a longer period of time.
Now, scientists from the University of California, Davis have answered several of these questions.
The researchers studied 21 cows on a farm for about five months. They taught the cows to get their food from inside a special hood, which allowed the scientists to measure the methane that the cows were giving off. This time, they used a much smaller amount of seaweed, which they mixed with the cows' food.
The results were surprisingly good. In some cases, the cows produced 82% less methane. The improvement depended on the kind of food the cows were given, but even the worst-polluting cows produced 33% less methane.
Over the five months, the scientists didn't see any signs that the cows' stomachs were getting used to the seaweed and starting to produce more methane again.
Another surprise came when they looked at the weight of the cows. The cows that were fed seaweed gained just as much weight as the other cows, but they didn't need as much food.
But there are still some big problems with the idea of feeding cows seaweed. For one thing, there's not adequate seaweed to feed all of the cows in the world. So farmers would have to figure out a way to grow lots of seaweed.
A bigger problem is that for most of their lives, cows live in fields, where they eat the grass. That means there's no chance to feed them seaweed every day. These problems need to be taken seriously if the world is going to avoid the worst effects of the climate crisis.
Still, it's true that something as simple as feeding cows seaweed can help reduce some of the pollution causing the climate crisis.

Last week, the United Nations (UN) released the most complete report ever created on the global problem of food waste. It found that the world wastes about 17% of all the food produced. That's about a billion tons of food a year.
A billion tons is a lot of food — it's over 2 trillion (2 ,000 ,000 ,000 ,000) pounds or about 931 billion (931 ,000 ,000 ,000) kilograms. The report says that the amount wasted is roughly twice as much as earlier studies had suggested.
The report was produced by the UN's Environment Program (UNEP) and covered food waste around the world in 2019. The study showed a several different ways in which food was wasted — at home, in restaurants and in stores.
It turns out that by far, most food waste — about 61% — happens horse. On average, the amount of food thrown out at home works out to about 163 pounds (74 kilograms) for each person every year.
Restaurants were responsible for about 26% of the food wasted. The remaining 13% was thrown away by stores.
Many people thought rich countries were more likely to waste food than countries that were less rich. That turned out not to be true. One surprising discovery was that food was wasted at about the same rate in all but the poorest countries. (The UN had difficulty measuring food waste in the poorest countries.)
But people in richer countries may waste less food at home because they are eating out at restaurants more often. That certainly seems to be the case in the US, which has low waste numbers for homes, but quite high numbers for restaurants.
In some cases, labels might be causing food waste, the report said. People might be throwing away food even though it's still good to eat, simply because the container's "Best By" or "Sell By" date has passed. In poorer countries, food may be wasted because not all homes have a refrigerator.
Why is wasting food such a problem? For one thing, the report points out, hundreds of millions of people went hungry in 2019. Also, wasting food is really bad for the planet. Farming creates between 10% and 30% of the world's greenhouse gas emissions (排放) — the pollution that's making the climate crisis worse. So when food gets thrown out, the pollution is created for nothing.
The UNEP report says that it's important for countries to study food waste more carefully in order to figure out ways to solve the problem.

7 . Henry Cavill: Bring Superman to Life
Henry Cavill knew that he wanted to be a star at 16 years of age, after a chance meeting with movie star Russell Crowe who inspired his passion for acting. But for the British-born actor, the bright lights and attraction of Hollywood were a long way away. Supported by his secretary mother and stockbroker father, he decided to study drama during high school. His journey to super star began.
Before gaining the international recognition he has now, Cavill tried out for roles in the Harry Potter and Twilight series but failed to get either. He would have to keep waiting for his big chance.
Determined as ever, Cavill took any acting jobs he could get his hands on and appeared in several low-budget horror movies and TV shows in hopes of getting noticed. It almost worked. In the early 2000s, at just 22 years old, he narrowly missed out on becoming the new James Bond. Finally, in 2007, his hard work paid off. He won a leading role as the first Duke of Suffolk in the period show The Tudors. The TV show was very popular and helped to raise Cavill's popularity in America.
In 2011, Cavil landed his breakout role, playing Superman in the DC Extended Universe. He hasn't looked back and has since starred in many hit films, such as Mission: Impossible- Fallout.
More recently, he stepped back on to the small screen. Since 2019, he has starred in the popular series The Witcher, adapted from the book series and video games of the same name. In the TV show, Cavill played a brave monster hunter named Geralt of Rivia, which was the perfect role for Cavill because he was a fan of the video games. Cavill also got a chance to play a classic English character — master detective Sherlock Holmes — in 2020's Enola Holmes.
However, Cavill isn't just a good guy on screen. His charity work also makes him a real-life hero. In 2014, he took part in the Ice Bucket Challenge while wearing his full Superman suit to support the ALS Association. Currently, he is an ambassador for the UK's Royal Marines Charity, which supports war veterans (退伍军人). Why does he do it? He love to make people feel good and bring smiles to people' faces. Indeed, Henry Cavill in living proof that you don't always need to wear a cape (斗篷) to act like a hero.
