Today, the world’s diversity(多样性) of food crops is quickly decreasing. But scientists around the world are taking action. They are building seed banks. At seed banks, scientists store the seeds of many different crops.
There are now 1,400 seed banks around the world. However, some banks are in warm countries. If the electricity fails, the seeds will get too hot and die. Other seed banks are in countries troubled by war. Sometimes people damage the seed banks. If this happens, valuable seeds can be lost forever!
The organization Global Crop Diversity Trust decided they wanted to deal with this problem. So, they decided to build a global seed bank. This seed bank would contain a back-up, or extra copy, of all the world’s seeds. Smaller seed banks would still collect and keep local seeds. But they would also send copies of their seeds to the global bank.
Scientists from the Global Crop Diversity Trust chose the cold, snowy mountains of Svalbard, Norway to build the global seed bank — the Svalbard Global Seed Vault. Organizations, farmers, or local seed banks store their extra seeds there. And the people who place their seeds in the vault are the only people who can take them out. They pay to ship their seeds to Norway, but it does not cost them any money to store their seeds. The Global Crop Diversity Trust pays for this.
Cary Fowler is a scientist who heads the Global Crop Diversity Trust. He said, “If the Seed Vault simply supplies seed banks with copies of seeds that those banks lost by accident, the Seed Vault will be worth way more than it cost.”

The traditional Chinese lunar calendar divides the year into 24 solar terms. Grain Rain(谷雨),as the last term in spring, starts on April 19 and ends on May 4.
Grain Rain comes from the old saying, “Rain brings the growth of hundreds of grains”, which shows that this period of rainfall is very important for the growth of crops. Here’s something that you may not know about the Grain Rain.
1. Grain Rain falls between the end of spring and the beginning of summer, and the temperature rises much higher than it does in March. With dry soil and heavy winds, sandstorms may happen more often. |
2. There is an old custom in southern China that people drink tea on the day of Grain Rain. Spring tea during Grain Rain is good for the eyes. It is also said that drinking tea on this day would prevent bad luck. |
3. People in northern China have the tradition to eat the vegetable toona sinensis during Grain Rain. An old Chinese saying goes “toona sinensis before the rain is as tender as silk”. The vegetable is good for the stomach and skin. |
4. The Grain Rain Festival is celebrated by fishing villages in northern China. Grain Rain marks the start of the fishermen's first voyage of the year. The custom dates back to more than 2,000 years ago. |
