Well, not exactly. Scientists recently grew plants in lunar soil for the first time in history. The lunar soil, also called moon dust, was brought back from three Apollo missions. Scientists from the University of Florida planted thale cress in the moon dust and compared the growth to materials found on Earth’s surface, such as volcanic ash. Thale cress is a small, bitter-tasting plant similar to broccoli, cauliflower, and kale. After two days, the seeds had germinated (grown). However, the plants in moon soil did not thrive compared to the plants in Earth soil after six days.

Lunar soil is very different from the soil on Earth. Soil is the mixture of minerals, organic matter, and other materials that covers most of Earth’s land. Soil is a storehouse of nutrients and the decayed remains of organisms (living things). Lunar soil is more dusty and is not made up of decayed organisms, so it does not contain as many nutrients compared to soil found on Earth. Impacts of micrometeoroids (tiny meteoroids‘) grind the surface rocks into a fine, dusty powder known as regolith. Regolith overlies all the bedrock on the moon. Because regolith forms as a result of exposure to space, the longer a rock is exposed, the thicker the regolith that forms on it.

National Aeronautics and Space Association (NASA) granted the scientists 12 grams of lunar soil for the experiment because it is precious and cannot be wasted. The soil brought back from Apollo 11 was not as strong as the soil brought back from Apollo 12 and 17. The scientists believe soil from Apollo 11 was damaged by cosmic rays and radiation from solar wind on the moon’s surface. Scientists have already started planning where they could find better moon soil where lava flow has enriched the soil.

For years, scientists have wondered whether the moon could support life. If humans were to survive on the moon permanently, they would need to grow plants for food. Although the experiment did not prove that the moon could sustain life, it gives hope that there could be vegetation on the moon someday. We are one step closer to growing an herb garden on the moon!

Last week, on February 24, the 1 millionth variety of seed was added to the Svalbard Global Seed Vault located on Spitsbergen, an island off the coast of Norway. The facility was designed as a “doomsday vault” to store seeds from millions of plants, including nearly all the world’s food crops. These seeds may be needed in the future to reestablish crops destroyed by major disasters.

The newest additions that put the vault over the million mark included samples of beans, corn, and squash from India, Mali, Peru, and the Cherokee Nation in the United States. The new contributions also included clover, grass, and herb seeds from the United Kingdom’s Kew Gardens.

The Svalbard Global Seed Vault is the largest seed storage facility in the world. The vault can hold up to 4.5 million seed samples from wild and domesticated plants.. Many of the seeds come from crop varieties that are not widely grown, as well as from staple food crops. The genetic diversity in the stored seeds may help scientists develop new crop varieties that can thrive in climates and soil conditions different from those that exist today. The Svalbard facility opened in 2008.

The plan for a doomsday vault originated with the United Nations International Seed Treaty of 2001. The site at Spitsbergen was chosen because it is an unlikely place for a disaster to occur. The site is remote, largely uninhabited, geologically stable, and naturally cold. The seed vault was built in an abandoned coal mine about 490 feet (150 meters) deep in the side of a mountain. The vault lies within permafrost, a layer of earth that remains frozen the year around. The vault is kept at a temperature of –0.4 ºF (–18 ºC). The low temperature keeps the seeds viable—that is, able to germinate under proper conditions—for long periods.

There are many smaller seed vaults in other parts of the world. Such facilities, often called gene banks, help preserve genetic diversity in food crops. The Svalbard facility serves as a global reserve gene bank. In 2015, researchers removed some seeds from the Svalbard vault for the first time. They used some of the seeds to replenish the supply at a gene bank in Aleppo, Syria. Some of that gene bank’s seeds had been lost during Syria’s ongoing civil war.

The Svalbard Global Seed Vault is owned and administered by the government of Norway. Daily operations are overseen by the Nordic Genetic Resource Centre, a Scandinavian organization dedicated to the sustainable use of plants, farm animals, and forests. Sustainability is the ability of an activity or way of life to continue over the long term without exhausting resources, damaging the environment, or harming people. The Crop Trust, established by the United Nations Food and Agriculture Organization, helps fund the operation of the seed vault. The seeds stored at the Svalbard Global Seed Vault are owned by the gene banks that have deposited them there.

Yesterday, March 3, was World Wildlife Day, an international celebration of the Earth’s flora and fauna sponsored by the United Nations (UN). This year’s theme, “Life Below Water: For People and Planet,” singled out the crucial ecosystems and marine life of the world’s oceans. Life on Earth depends on the conservation and sustainable use of the oceans.

The first UN World Wildlife Day was celebrated on March 3, 2013, the 40th anniversary of the signing of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) in 1973. The treaty—which went into effect in 1975—aims to control trade in wild animals and plants, their parts, and products derived from them. Over 170 countries around the world have joined the treaty. CITES forbids commercial international trade in certain endangered species, and it regulates trade in other species that might otherwise become endangered. Nevertheless, international wildlife trade continues to put many species at risk.

This year’s World Wildlife Day theme drew particular attention to the diverse animal and plant species that inhabit the world’s oceans. It also highlighted the importance of the oceans themselves, which—aside from providing energy, food, livelihoods, medicines, natural resources, recreation, sediments, and transportation—also absorb about 30 percent of the carbon dioxide produced by humans, buffering the impacts of global warming.

Unfortunately, many ocean waters are polluted, and plastic marine debris in particular is poisoning the world’s waters and killing marine wildlife. Overfishing and other forms of exploitation are also reducing marine wildlife populations, as are the losses of coastal habitats and the effects of climate change. The goal of “Life Below Water: For People and Planet” was to raise awareness of the importance of marine life and to instruct people on responsible and sustainable behavior that can limit the many perils facing the world’s oceans.

Today, May 4, is a holiday in Japan known as Greenery Day, a day dedicated to nature and the environment. On Greenery Day, commemorative plantings of trees take place throughout the country and events celebrate the beauty and importance of nature. Until 2007, Greenery Day was celebrated on April 29, the birthday of former Emperor Hirohito, whose reign name was Showa. Hirohito was known for his love of plants and nature.

Before being designated Greenery Day, May 4 was a national holiday already, simply because it fell between two other holidays: Constitution Day (May 3) and Children’s Day (May 5). (In Japan, a day between two holidays automatically becomes a holiday.) Add Showa Day (which replaced Greenery Day on April 29), and Japan has four holidays during a seven-day period known as “Golden Week.” Many businesses are closed during Golden Week, and many people enjoy an extended time away from work.

Japan’s current emperor, Akihito, is expected to abdicate on April 30, 2019. His son Crown Prince Naruhito will then ascend the Chrysanthemum Throne on May 1. The government may make these days national holidays as well, in which case May 2—sandwiched between holidays—would also become a national holiday. As a result, all seven days of Japan’s spring Golden Week would be holidays. In any case, the Emperor’s Birthday holiday—December 23 for Akihito—will switch to February 23, Naruhito’s birthday.

Japan currently celebrates 16 national holidays, more than many other countries observe. The United States has 10 federal holidays. Canada has 9 (with more scheduled by province), and Australia has 7 (but more are instituted by local governments).
