How can a creature weighing over 5 tons and normally taking 150 kilograms of food and 120 liters of water per day survive in a desert environment?
In the southwest African country of Namibia, and the Sahara lands of Mali further north, the desert elephant does just that.
Although not regarded as a separate species from the African elephant, the desert cousin differs in many ways. Their bodies are smaller, to absorb less heat, and their feet are larger for easier walking across sandy surfaces. They are taller, to reach higher branches. They have shorter tusks (象牙), and most importantly, longer trunks to dig for water in riverbeds.
Desert elephants can travel over 70 kilometers in search for feeding grounds and waterholes, and have a larger group of families, They drink only every 3-4 days, and can store water in a “bag” at the back of their throat, which is only used when badly needed. Desert elephants are careful feeders — they seldom root up trees and break fewer branches, and thus keep what little food sources are available. Yong elephants may even eat the dung (粪便)of the female leader of a group when facing food shortage.
During drought (干旱) they are unlikely to give birth to their young but with good rains the birthrate will increase greatly. Desert elephants have sand baths, sometimes adding their own urine (尿液) to make them muddy!
As we continue to overheat our weak planet, it can only be hoped that other animal species will adapt (适应) as extraordinarily well to change as the desert elephant.

【推荐1】Richard Croft had never struggled to feed his three dogs before, but when he was forced to stop working after being diagnosed with cancer, their monthly food bill was difficult to keep up with. He is one of dozens of people who have turned to the Blue Cross pet food bank in Grimsby, set up in June to help people in the area struggling to feed their pets amid the cost of living crisis.
Stocked (提供货物) entirely by donations from the local community, there is a steady stream of people stopping by to pick up food for their dogs and cats every Tuesday and Thursday. In a two-hour period last Tuesday, the food bank helped 76 animals from 32 families.
“Week on week we’re seeing more and more people. As fast as the food is coming in, it’s literally touching the shelf and going back out again,” said Cristina Pool, who runs the service alongside her fellow veterinary (兽医) nurse, Hannah Cardey.
“A lot of people come and they actually get quite emotional,” said Cardey. “Some people feel a bit embarrassed that it’s come to the point where they can’t feed their pet. For some people their pet is like their child, so they feel quite ashamed.”
The origins of the food bank started in January, when staff at the Grimsby Blue Cross animal hospital noticed an increase in emaciated (憔悴的) animals coming in for treatment who clearly were not getting the right nutrition. “There was a particular one, a really emaciated boxer dog. So she was one of the cases that made us think, there really is a need for this,” said Pool.
After first operating out of a cupboard, the food bank is now based in a small building next to the animal hospital, and the Blue Cross is rolling out the pet food bank plan nationally.

【推荐2】The millipede (千足虫)
Forest life
The importance of leaves
When leaves begin to die in autumn, they turn from green to yellow and fall from the trees.
Food on the forest floor
Some living things, like mushrooms, break the leaves into smaller pieces and eat them. In a few months there is nothing left of them. But for mushrooms, not all trees are the same. Mushrooms prefer some types of leaves to others. This means that some leaves take much longer to break down than others, sometimes years. So what happens to these?
More on the menu
The millipede also likes leaves and it eats any type. But when it has finished, it produces waste. This waste then becomes the food of mushrooms. When mushrooms eat leaves they choose only certain types — But when they eat waste, they will eat any kind.
So next time you are walking through a forest, remember that something may be having a meal right under your feet!

【推荐3】The Adélie penguin, who has been named Pingu, was discovered by a local resident Harry Singh “looking lost” on the shores of New Zealand, over 3,000 kilometers away from its natural habitat.
“At first I thought it was a soft toy,” Singh told the BBC. “But suddenly the penguin moved his head, so I realized it was real. It didn’t move for one hour... and looked exhausted.” He then called penguin rescuers as he was concerned that it was not getting into the water, making it a potential target for any predatory (捕食性的) animals wandering on the beach.
On arriving at the scene, Thomas Stracke, who has been rehabilitating (康复) penguins on New Zealand’s South Island for the last 10 years, was shocked to find that the penguin was an Adélie — a species that lives exclusively on the Antarctic peninsula. Stracke said, “It is quite unusual since they are known only living in the Antarctic area. Fortunately, apart from being a bit starving and severely dehydrated, he was actually not too bad, so we gave him some fluids and some fish smoothie.”
It is only the third recorded incident of an Adélie penguin being found on New Zealand’s coast — the previous were in 1962 and 1993 — and although sitings remain incredibly rare, if they become more common it could be a worrying sign, say experts.
“I think if we started getting annual arrivals of Adélie penguins, we’d go actually, something’s changed in the ocean that we need to understand,” Otago University zoology professor Philip Seddon told The Guardian. “More studies will give us more understanding where penguins go, what they do, what the population trends are like — they’re going to tell us something about the health of that ocean ecosystem in general.”
Pingu has now been released into a bay on the Banks Peninsula, and it is hoped he may be able to make the journey home.

【推荐1】If you come to Vancouver, you can appreciate the magnificent mountain scenery or the beautiful coast. It has more than 100 parks, mainly in the style of Britain and North America, but also in the oriental style, typical of China. Vancouver has some of the mildest weather, making it an ideal destination to explore.
Dr. Sun Yat-Sen Classical Garden
The garden is to maintain and enhance the bridge of understanding between Chinese and western cultures, as well as promote Chinese culture generally. Remember to bring some souvenirs back home at one of the Asian specialty stores!
VanDusen Botanical Garden
The garden is well kept with an amazing variety of trees and flowering plants. If you are visiting during the winter season, the light festival in December is a must see! The garden is transformed into a Christmas wonderland that will attract everyone, from child to adult.
Stanley Park
It is a massive green space on the northwest side of the city. It is also the perfect place to take a stroll or bike ride and take a horse and carriage ride. The 400-hectare park is a local's favorite and includes multiple dining outlets, swimming pools, ice rinks, golf courses, and more.
Capilano Suspension Park
Travelers who love the thrill of heights and gorgeous rainforest views are handsomely rewarded at the Capilano Suspension Park.

【推荐2】You must think a computer is the best thing in the world, right? You must think it works at a super speed and can do everything? Well, it’s not! In fact, the brain is much more powerful than any super computer! Think about when a glass is just about to fall off the table. Your brain controls everything that you need to do to save that glass from falling. First your eyes check out what’s going on, then tell your brain, and your brain decides how quickly you need to react (反应), and then your muscles (肌肉) go into action. That is just from your brain. No computer could ever come close to that!
The brain weighs just 3 pounds, but it controls everything you do from thinking, learning, feeling even to breathing and your heart beating. Even though the brain is just 2% of your body weight, it uses around 20% of all your energy in your body. That is a lot for such a small organ. There are about 100 billion tiny, tiny little cells (细胞) in your brain. There are so many that it would take you over 3,000 years to count them all!
Your brain stops growing when you’re 18, but it actually keeps on developing and learning new things. So your parents are really super smart! You won’t be able to fool them! Believe it or not, your brain NEVER stops working. Even during sleeping, the brain works for long-term memory establishment. It is realized that the brain is the second organ in the body as the heart that never stops during human lives.
So everyone should be proud of such a gift of nature.
