Climate Change 
Climate change is the changes in the earth’s atmosphere including changes in temperature, wind patterns and rainfall. Nowadays, climate change has become a major global concern. There are many causes of climate change. The main cause is the increase of temperature due to emission of carbon gases in our atmosphere.
Carbon gases are being emitted in various ways. First of all, modern people are going to be more and more machines emit hot gases in the atmosphere. Mills and factories, railway engines, buses, cars etc. burn fossil fuels and emit carbon gases.
It is well known that climate change has a very bad effect on our environment. Due to this change the huge ice caps of the Polar Regions are being melted and the sea levels are being risen up. Besides climate change will reduce crop production and will drastically reduce man’s ability to work.
The worst sufferer of climate change is the low- lying countries in the world that can go under water due to sea- level rise. Obviously, climate change is a great threat to Bangladesh because Bangladesh is a low- lying country and might one day go under water due to sea- level rise.
It is true that in today’s world we cannot stop climate change, but certainly, we can minimize the change by taking some steps. We can reduce carbon gas emission by reducing the use of fossil fuels. We can make people aware about the disastrous effect of climate change and thus inspire them to act properly.

Food Adulteration
Food adulteration means adding or mixing another substance to a food item in order to make more profit, preserve it for a long time or make it appealing. It reduces the actual quality of food item and causes health hazards. It is considered to be one of the major problems in our country. There is hardly any food that is not adulterated in one way or another.
There are many bad impacts of adulterated food. They are generally harmful to health and cause serious health problems like digest problem, diarrhea, dysentery, cancer, kidney failure, heart problem etc. The adulterated foods are nothing but slow poison that’s kills people slowly. Nowadays adulteration of food in our country is so widespread that it is difficult to find a food item which is safe to eat. Milk and milk products are poorly processed, vegetables have pesticides with item, fishes are preserved with formalin and fruits are preserved with poisonous chemicals. A recent survey conducted in some areas of Dhaka city reports that 40% of 82% samples of, milk products, fish, fruits and vegetables contained DDT, Aldrin and other poisonous chemicals. It is not unknown that strict monitoring and supervision in the production process can control food adulteration to a great extent. It is not possible for Govt. alone to control the widespread adulteration of foods. General public should be aware and should boycott the product that is detected to be adulterated. Also, Govt. must enact strict laws against adulteration. Capital punishment should be ensured to the dishonest traders who are involved in food adulteration.

A School Library
A school library is a library where the students and teachers of a school can read and borrow books. A library satisfies our eternal knowledge of the unknown and the unseen. A library is a part and parcel of a school. It is also a store-house of knowledge. It helps a person to satisfy his thirst for knowledge. No school is complete without a library. Our school has a big library. It is situated in a separate building. The library has a good collection of different books. The library is divided into two parts. One is reading room and another is librarian room. In reading room there are some chairs, tables or benches to sit. In the librarian room there are many almirahs and shelves. Books are arranged in shelves according to subjects. We can borrow books after two weeks from the library. Because of having a good collection of books the students and the teachers of the school can read books and make notes according to their choice. In fact, we are really proud of our school library.
