The causes of extinction come from population growth, pollution and deforestation. Therefore, in the past time, the “apocalyptic vaults” to store the seeds of the world began to be built. In South Korea, the Baekdudaegan National Arboretum Seed Conservation Center currently preserves nearly 100,000 seeds from 4,751 plant species to ensure they are not affected by “apocalyptic events”.

Mr. Lee Sang-yong, head of the center, said that this is one of two places to store seeds in the world today. Unlike conventional seed banks, where samples are regularly taken out for different purposes, the seeds in the vault will stay there permanently, only to be used for the purpose of preventing extinction. The safest place in Korea The seed vault was designed by South Korea’s National Intelligence Service as a heavily guarded security facility, surrounded by a wire fence and dozens of cameras. Police regularly patrol the area and filming and photography are limited. Inside, an elevator will lead underground with a depth of about eight floors, to the concrete tunnel in the cave, where heavy steel doors guard the storage room. The storage room will be kept at -20 degrees Celsius with 40% humidity to preserve seeds. Mr. Lee said the bunker was built in “the safest place” in South Korea, designed to withstand a 6.9-magnitude earthquake and even a nuclear attack. “Geographically, it’s very safe,” Mr. Lee said. “We have opened a tunnel 46 meters deep underground to ensure the seed is safe from war and nuclear threats.” The seed samples in the cellar were mostly plants from the Korean peninsula. In addition, with a capacity of 2 million seeds, many countries such as Kazakhstan and Tajikistan also accept requests, sending seeds to this reserve. Countries that send seeds here will have title to those seeds and can receive them back when needed. A researcher is doing experimental planting at the wild plant seed research department.

So the best-case scenario is that the seeds never have to be brought out.” “Run with time” The conservation of the seeds of wild plants – the original source of the crops we eat today – should not be overlooked, the researchers say. However, according to a recent United Nations report, many plants that help people ensure food security are “lacking effective protection.” The report warns against crops that are less resilient to climate change, pests and pathogens, and emphasizes: “The biodiversity of ecosystems, where humanity lives, is declining faster than any other any time in human history”. In its 2020 report, the Royal Botanic Gardens, Kew, UK, said many species of plants in the wild hold promise for future medicine, fuel and food. However, about two-fifths of them are threatened with extinction, largely due to habitat destruction and climate change. It is a “race against time” to determine which seeds are in danger of extinction before they completely disappear from the world, the report added. However, Na Chae-sun, a senior researcher at the Baekdudaegan National Arboretum, said studies on seeds of wild plants were “very much lacking”. “One might ask why riverside wildflowers are important,” she says. “In fact, the crops we eat today may have descended from this unnamed flower.” A researcher is examining a ‘black box’ containing seeds in a storage room.

Besides the vault in South Korea, another seed warehouse was also built in the heart of the mountain near the city of Longyearbyen on the island of Spitsbergen in Norway’s Svalbard archipelago, about 1,300 km from the North Pole. Dubbed the “Noah’s Ark” of food crops, the Global Seed Vault is the largest and most famous vault in the world. The facility is focused on preserving agricultural crops and related crops, storing more than a million seed samples from nearly every country on the planet.

Mr. James Munford (retired military service) and Mrs. Clarissa Munford (owner of a catering business) bought the house with the savings of the couple. At the end of October 2020, James and his wife decided to move to a new house to live. While packing, the couple was surprised to discover a hidden and forgotten “vault” in this very house. Accordingly, when he opened the wardrobe drawer to check, Mr. James was startled when inside there were many ancient coins made of gold and silver. Ancient silver and gold coins hidden in the closet When they took it out, they found a total of two boxes containing 64 ancient coins, including 46 $5 Liberty gold coins and 18 Morgan silver coins. These ancient coins are believed to date back to the 1800s, and are very valuable. “They look very old, but they look absolutely worth it,” Mr James said. Legally, the James and his wife bought the house and what they unearthed in the house will be legal property. However, he and his wife did not do so. Mr. James took pictures of these ancient coins and sent them to the former owner of the house to confirm and return to its owner. “I simply thought it wasn’t our property and I really don’t know the exact value of these coins. They could be family heirlooms, so I want the owner The true owner of this “treasure” received them,’ Mr. James confided. Then, the old owner of the house came to ask for this antique back. This person said that the coins could be worth up to $ 25,000 (about 572 million dong). The previous owner said that he kept these 2 boxes in a drawer a few months ago. When moving house, because he was in a hurry, he forgot 2 boxes and didn’t remember anything until Mr. James contacted him. He said he still keeps part of the coin collection in the safe.
