21 February is a memorable day in our national history. We observe the day every year as International Mother Language Day. The day is a national holiday. On this day, we pay tribute to the martyrs who laid down their lives to establish Bangla as a state language in undivided Pakistan in 1952. The struggle to achieve our language rights is known as the Language Movement. The seed of the Language Movement was sown on 21 March 1948 when Mohammad ALi Jinnah, the Governor General of Pakistan, declared in a public meeting in Dhaka that Urdu would be the only state language of Pakistan. The declaration raised a storm of protest all over the country. The protest continued non-stop, gathering momentum day by day. It turned into a movement and reached its climax in 1952. The government outlawed all sorts of public meetings and rallies to stop it. The students of Dhaka University defied the law and brought out a peaceful protest procession on 21 February 1952. When the procession reached near Dhaka Medical College, the police opened fire on the students, killing Salam, Rafiq, Barkat, Safiur and Jabbar. As a result, there were mass protests all over the country and the government had to declare Bangla as a state language. This kindled the sparks of independence movement of Bangladesh.

Air pollution comes from a wide variety of sources. In Bangladesh poisonous exhausts from industrial plants, brick kilns, old or poorly-serviced vehicles and dust from roads and construction sites are some of the major sources of air pollution. We can minimise this type of pollution by making less use of motor vehicles and avoiding the use of vehicles older than 20 years. We may also use proper lubricants to lessen the level of emission and pollutants. We can encourage people to use Compressed Natural Gas (CNG) or Liquid Petroleum Gas (LPG) for fuelling their cars. The government may relocate hazardous industries like brick kilns to areas away from human habitations.

In 1912, an American Shipping Company launched a new ship called "The Titanic'. It was the largest and most luxurious ocean liner of the time. It weighted 52,310 tonnes and could carry about 3327 passengers. Experts said that nothing could make it sink. On April 10, 1912 the ship sailed on its first voyage across the Atlantic. It sailed from Southampton in England to New York in the United States with 2224 passengers of men, women and children.
On April 15, just before midnight the ship struck the iceberg. The iceberg tore a great hole in the ship's side and the unsinkable Titanic began to sink. There was a great alarm on board. Warning bells rang out. Every one rushed to the life boat but there was not enough room for them all. There was room for only 1178 passengers. The lifeboats took mostly the women and children. It was a terrible scene.
