SPEECH/ESSAY ON POLLUTION.

                              POLLUTION

              Pollution is a problem because human beings, in an ever-increasingly populated and industrialised world, are upsetting the environment in which they live. Scientists maintain that one of humanity's greatest errors has been to equate growth with advancement. Now "growth" industries are being looked on with suspicion in case their side effects damage the environment and disrupt the relationship of different forms of life.

               The growing population makes increasing demands on the world's fixed supply of air, water and land. This rise in population is accomplished by the desire of more and more people for a better standard of living. Therefore greater demands for electricity, water and goods result in an ever-increasingly amount of waste material to be disposed of.

                The problem has been causing increasing consern to living things and their environment. Human beings are not solving these problems quickly enough. Their selfish pursuit of no return before they fully appreciate the damages.

               Ecologists  are of the opinion that we are so determined to possess a new car or washing machine, or to obtain a greater yield from our crops by the use of fertilisers, that we ignore the fact that life depends on a lot of micro-organisms  working efficiently.


               If new chemicals were released into the environment, a combination of them will most probably poison one or more of the different types of bacteria in soil and water, which are essential to keep nitrogen being circulated from the air into Organic material and being cycled back into the air again. If this should happen on a worldwide scale, the air would become unbreakable.


  

                For this reason, government worldwide are taking drastic steps to control global warming, water and soil pollution, air and noise pollution.

                             ESSAY ON  HOLI FESTIVAL           Holi is n ot just a festival of colours but has a religious significance.            It is believed that Prahlad, the son of Hiranyakashyap , a great devotee of Lord Vishnu was asked by his father,who was a demon, to stop worshipping Lord Vishnu.                        Prahlad refused to do so and his father got so annoyed that he ordered his sister Holika, to sit in a burning pyre and burn Prahlad. As Prahlad had the protection of Lord Vishnu, nothing happened to him; instead Holika died a most painful death and was reduced to ashes. Holi therefore, signifies the victory of good over evil.                        Who cannot associate Holi with colour, dance and song? It is one of the most enjoyable festival of North India.

      Festival of lights                ESSAY ON DIWALI FESTIVAL          As we know that DIWALI is a festival of lights. Many people come together to celebrate this festival. The religious significance of the festival goes back to the day when Rama returned to Ayodhya after being in exile for fourteen years. He returned after slaying Ravana, the evil king of  demons, who had kept Rama and Sita his wife, and his brother Lakshman captive. In South India it is believed that Lord Krishna killed the evil Narkasura and brought peace on earth.             The tradition of lighting up the house with diyas or candles and today even electric bulbs goes back to this when the whole of Ayodhya was lit up to welcome Rama,Sita and Lakshman. Hence Diwali is known as the festival of lights.             Diwali has no fixed date and is celebrated in the month of October or November and it heralds the winter.             Preparation for Diwali begins well in advance with the whitewa
