That's the message Edmonton Mayor Don Iveson and city councilor Amarjeet Sohi voiced when they declared Feb. 21 to be International Mother Language Day (IMLD) in Edmonton, the capital of the Canadian province of Alberta. The pair were on hand for the International and Heriage Languages Association's (IHLA) 12th annual Mother Language Day celebrations in an effort to save endangered languages. "Keeping languages alive is important for me richness of our culture and the diversity that strengthens Edmonton," said Iveson. There are nearly 7,000 unique languages spoken worldwide, but according to data from the United Nations Educational, Scientific and Cultural Organization (UNESCO) half of those languages are at risk of going extinct in just a few generations. For example, there are currently over 3,000 languages spoken throughout Africa. This sounds impressive until you realize that there were over 10,000 languages spoken on the continent before colonization during the 19th century. "People who lose their language experience suffering," said Olenka Bilash, professor of second language education at the University of Alberta. Bilash likened the loss of language to the loss of cultural identity. "As a multicultural society, it is very important to continue to preserve and pass on to future generations the language, culture, traditions and customs that we bring to Canada, " said IHLA president Olga Prokhorova. While the City of Edmonton's citizen and new arrival centre in city hall provides services in 150 languages, Bilash said research shows that "most people are still uncomfortable speaking their own language in public spaces." Bliash hopes the official announcement of International Mother Language Day in Edmonton----which _ International Mother Language Day declared by UNESCO in 1999 ---- will be a step toward encouraging more language diversity in order to preserve the cultures tied to them. "Our words define us; our expressions and vocabulary define who we are as people," said Marueen...

Nuclear radiation has a certain mystery about it, partly because it cannot be detected by human senses. It can't be seen or heard, or touched or tasted, even though it may be all around us. There are other things like that. For example, radio waves are all around us but we can't detect them, sense them, without a radio receiver. Similarly, we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things. At very high levels, radiation can kill an animal or human being immediately by killing masses of cells in vital organs. But even the lowest levels can do serious damage. There is no levels of radiation that is completely safe. If the radiation does not hit anything important, the damage may not be serious. This is the case when only a few cells are hit, and if they are killed immediately. Your body will replace the dead cells with healthy ones. But if the few cells are only damaged, and if they reproduce themselves, you may be in trouble. They can grow into cancer. Sometimes this does not show up for many years. This is another reason for some of the mystery about nuclear radiation. Serious damage can be done without the victim being aware at the time that damage has occurred. A person can be irradiated and feel fine, then die for cancer five, ten, or twenty years later as a result. Or a child can be born weak as a result of radiation absorbed by its grandparents. Radiation can hurt us. We must know the truth. Question: If a human being is hit by nuclear radiation, he may _ . - die of cancer after many years - die immediately - have a child who may be born weak - all of the above
all of the above

Change is what keeps our lives moving, and allows us to achieve what we desire and deserve. Like it or not, we need to be willing to go with the flow, and be adaptable when something doesn't go according to plan.

It's like trying to stick to a diet in a house that is filled with chips, cookies, ice cream and chocolate; you are just making it more difficult for yourself.
