• Tobacco use has predominantly negative effects on human health and concern about the health effects of tobacco has a long history.
•  Tobacco also contains nicotine, which is a highly addictive psychoactive drug.
• When tobacco is smoked, nicotine causes physical and psychological dependency. 
• Tobacco use leads most commonly to diseases affecting the heart, liver and lungs. Smoking is a major risk factor for heart attacks, strokes, chronic obstructive pulmonary disease (COPD) (including emphysema, asthma and chronic bronchitis), and several cancers (particularly lung cancer, cancers of the larynx and mouth, bladder cancer, and pancreatic cancer). It also causes peripheral arterial disease and high blood pressure. Hence, Consumption of tobacco causes COPD, Cancer and Asthma.

• Pulse Polio is an immunisation campaign established by the government of India to eliminate poliomyelitis (polio) in India by vaccinating all children under the age of five years against the polio virus. 
• The project fights poliomyelitis through a large-scale, pulse vaccination programme and monitoring for polio cases. 
• Tamil Nadu will hold a pulse polio immunisation camp on March 10 as part of a nationwide campaign. In 2019, Tamil Nadu is stepping into the 15th polio-free year. Hence, Pulse Polio is an example of a vaccination program by the government.

• Hygiene is a set of practices performed to preserve health. According to the World Health Organization (WHO), "Hygiene refers to conditions and practices that help to maintain health and prevent the spread of diseases."
•  Personal hygiene refers to maintaining the body's cleanliness.
•  Many people equate hygiene with 'cleanliness,' but hygiene is a broad term. Hygiene includes such personal habit choices as to how frequently to take a shower or bathe, wash hands, trim fingernails, and change and wash clothes.
• Environmental hygiene includes attention to keeping surfaces in the home and workplace, including bathroom facilities, clean and pathogen-free and maintenance of dustbins for garbage. Hence, Keeping the house clean, Throwing garbage in the dustbins and keeping dustbins covered is a part of environmental hygiene. 

Forests helps in producing rainfall. More are the trees, the more water gets absorbed into clouds and the more it helps in rain falls. The roots of a tree make gaps in the soil so that when it rains the water can sink in before being absorbed by the soil. These spaces also allow air and water to reach the roots of the plants.  If the forests disappear, there will be less rain resulting in dryer conditions, that eventually lead to drought. Once this happens, the damage is extensive making it difficult to plant more trees or plants later because the soil is so hard and dry. When trees removed using heavy machinery, the soil is pushed down and the gaps fill in. Because all plants and trees need that water and air to reach roots, the conditions become unfriendly for new growth.

Greatest problem in water conservation is to reduce the amount of evaporation. Evaporation is a process by which a large amount of water evaporate in the form of water vapours (gaseous form)

The 'Sardar Sarovar Dam' is a gravity dam on the Narmada river near Navagam, Gujarat in India. It is the largest dam and part of the 'Narmada Valley Project'.

After the success of the basic programme is space research and rocket related project, Indian Space research Organisation was established on 15th August 1969 in order to carry out further space research.

Aryabhata, the first satellite built by India, was launched on this day April 19, in the year 1975. Aryabhata was built by the Indian Space Research Organization (ISRO) to conduct experiments in X-ray astronomy, agronomics, and solar physics. The aim of the launching of the Aryabhatta satellite was for conducting scientific experiments for the study of the upper atmosphere.
