The Millennium Seed Bank Project, run by Kew Gardens—one of the oldest botanical gardens—will officially deposit the 24,200th species on Thursday, a pink, wild banana from China.
More than 50 countries are now on board with Kew"s giant task but vast places of the globe, including India and Brazil, still need to join in and donate seeds, director Paul Smith said.
The seed bank is one of the largest and most diverse in the world with more than 1.5 billion seeds. Its goal is to help protect the planet’s bio-diversity during a time of climate change.
The wild banana seed is under threat of extinction(灭绝) in southwest China from agricultural development. It is a vital food source for Asian elephants and important for growing bananas for human consumption.
Stored at minus-20 degrees centigrade, so they can last for thousands of years, the seeds await the day that scientists hope never comes—when the species no longer exist in the wild.
It is a race against time, Smith said, because in the last decade alone, 20 plants held in the bank have already been wiped out in the wild. He estimates that between a third and a quarter will become extinct this century.
"It is urgent a

Because most of the world"s food and medicines come from nature, protecting wild plant species is quite important, scientists say. There are already many other seed banks safeguarding food crops, which only account for 0.6 percent of plant diversity.
For Kew"s next goal—to collect a quarter of wild varieties by 2020—the botanists need 10 million pounds a year, or a further 100 million pounds on top of the 40 million they have already been granted.

But experts are now warning that the current shoe fashions will be causing teenagers discomfort in the short term and storing up years of foot, knee and back pain in the future.
Here, the experts identify the problems caused by teenagers" shoe choice.
![](http://img.shitiku.com.cn/uploads/allimg/20191219/20191219030734-15122.jpg)
Slip-on shoes with elastic (弹性的)sides are particularly popular among teenage boys - with Keds and Vans the most sought-after brands.
The main problem is that they are just too flat—so flat that the heel, which strikes the ground first, also becomes damaged and painful.
BALLET PUMPS

“As the shoe has no fastening device, it relies on the toes to keep the shoe on, causing an awkward gait(步法), this leads to short- and long-term problems such as calluses(茧子), heel and knee pain.”
WEDGES AND STILETTOS

Something in a natural, breathable fabric, with a string to hold it on, with a small heel and a deep toe-box that does not press the toes, such as Clark"s, Marks & Spencer or Rhino.

The second kind of medicine is called “natural cures” or “folk medicine”, in which less educated people try to cure sickness with various herbs. These folk healers also use observation and logic, but they are not so aware of it. They try things until they find something that seems to work, and then they keep doing that. Folk medicine flourished(兴起) long before the development of scientific medicine and was more successful in ancient times.
The third kind is called “health spas(水疗)” or “faith healing”. Sometimes this may be as simple as touching the holy man and being immediately healed. Other times, a magician may make you a magic charm, or say a spell(咒语), to cure you. Some religious groups organize healing shrines(圣坛) for the sick. In these places people rest, get plenty of sleep, eat healthy food, drink water instead of wine, and exercise in various ways. They also talk to the priests(牧师) and pray to the gods. If you are feeling depressed or you have been working too hard, going to these places may be just the right thing to make you feel better.
