Fun facts about Antarctica

At the southernmost point of the world, you find Antarctica a giant mass of ice that’s its own continent. You, may not know much about the continent, so why not read on?

There’ s a lake that runs blood red in Antarctica.

As though someone has cut into the ice, the properly named Blood Falls come out over the Taylor Glacier. The water is extremely high in iron and salt, and when it comes into contact with the air, it shows the special red color against the pure white surroundings. The water here is three times saltier than ocean water, and therefore, too salty to become ice.

Antarctica has its own treaty (条约).

Because the environment of Antarctica is so delicate and unique, there is a treaty saying that only peaceful research can be done there. In 1959, 12 countries signed this treaty, with the number now sitting at 53. This also makes it certain that Antarctica doesn’t end up being caught in an international conflict, and that the continent is only used for scientific purposes and sensible traveling. The treaty prevents army and nuclear activities, and also mineral mining.

There is a unique phenomenon in Antarctica called diamond dust.

While there are low levels of precipitation (降水) in Antarctica, that doesn’t mean the air is clear of nature’s beauty! The air is so cold there that moisture (水汽) can condense while air-borne. This results in ice falling to the ground. The sun’s light will cause the ice to shine, creating a shining shower called diamond dust. It happens when the skies are clear, known as clear-sky precipitation.

A major emergency can create hundreds of thousands of refugees (难民) overnight. The most immediate way in which organizations like UNHCR and the International Committee of the Red Cross (ICRC) can help these refugees is by setting up refugee camps. Refugee camps are designed to be temporary, but they often remain in place for decades. In some parts of the world, children have grown up and had children of their own without ever leaving their camp.

Critics argue that they force refugees to be entirely dependent on donations. One journalist who visited the Nyadeou camp in the south of the Republic of Guinea A (Africa) in 2001, described how normally peaceful people were reduced to fighting with each other when the food truck arrived.

Refugees camps can easily become dirty, overcrowded and are overrun with disease or crime. In many camps, drug dealers hide themselves among the majority of innocent refugees.

One alternative for refugees is to settle in a town or village, making them become part of the local population. This is known as the “self-settlement”. Several aid agencies argue that the self-settlement is a better option in many cases than refugee camps. They say that self-settled refugees can start to rebuild their lives straight away, and are freer and safer than refugees in camps. Oxfam, the ICRC and many other international aid agencies support programs in which refugees are helped to self-settle.

Representatives of UNHCR argue that refugee camps are the best way of saving the greatest possible numbers of lives. They point out that it is much easier to help people if they are all gathered in one place. This is certainly true of emergency relief, for example the distribution of food, water, shelters and medical supplies. It is also true that long-term aid programs, such as family tracing, orphan support and, perhaps most importantly, education, can all be carried out much more easily when refugees are all living together in one place.

America’s youth is turning its back on tobacco. According to a study recently published by the Centers for Disease Control and Prevention (CDC), cigarette smoking among US high school students is at an all-time low. One in 5 US high school students in 2016 reported using a tobacco product within the past 30 days, an improvement from 1 in 4 students just one year before.

“These findings show the importance of continuing to implement the evidence-based strategies that we now work to reduce all forms of tobacco product use, including e-cigarettes, among our nation’s youth,” says Brian King, of the CDC’s Office on Smoking and Health and senior author of the study.

And it’s not just tobacco: Drug use among US teens is down across the board. The National Institute on Drug Abuse has published annual reports on US teens’ drug use since 1996, and the 2016 survey shows the lowest rates of illegal drug and alcohol use. Marijuana (大麻) use remained “mostly steady”. “It is encouraging to see more young people making healthy choices not to use illegal substances,” says former National Drug Control Policy Director Michael Botticelli.

All individual forms of tobacco such as cigarettes, e-cigarettes, cigars, and smoke-less tobacco saw declines in usage in 2016. Experts are especially encouraged by the decline in cigarettes, the most popular tobacco product among teens. In 2016, 11.3 percent of high school students reported using e-cigarettes, down from 16 percent in 2015.

Dr. King says adaptation is key to the decline of e-cigarettes. “We have over a half-century of science telling students about the harmful effects of tobacco use and what works best to prevent it,” says King. “E-cigarettes are the most commonly used tobacco product among our nation’s youth, and it’s critical that our proven strategies are modernized to keep pace with the changing tobacco product landscape.”
