LESSON 6 | POLLUTION QUESTIONS AND ANSWERS

SCROLL DOWN BELOW FOR QUESTIONS ANSWERS

Can we live without water? No, we cannot. We need air to breathe, and the air we breathe must be clean and fresh. The air mixed with dust and smoke is polluted air. When polluted air goes into our lungs, we can fall ill.

When you visit an industrial area, what do you see? You see smoke coming out of chimneys. The air becomes thick with clouds of smoke. The fumes of cars, buses and trucks also fill the air.

Your ears are also filled with the noises of factories and trains. The smoke of factories and the fumes of automobiles make the air dirty. This is how air becomes polluted.

Air is polluted all the time by smoke and foul smells. Can we survive in such an environment? No, we cannot. What can we do then? We can take good care of our environment and protect it from being spoilt.

One of the ways of protecting the environment is to make people aware of the dangers of destroying the world around us.

Green plants enrich the air with oxygen. They use up the carbon dioxide and other harmful gases. In this way plants protect us from a number of diseases. So we must warn people of the dangers of cutting trees. We should plant more trees.

There are many other ways in which we can keep the air clean. Cars and buses should be cleaned regularly to reduce the release of harmful gases. Factories must adopt measures to protect the environment.

We must also take steps to keep the water clean. Like air, water is very valuable for us. We cannot live without water. We need water in our daily lives. People cannot survive in an environment where water is polluted either by natural causes or by man-made causes. You must have heard about the water of the Brahamaputra becoming dark and polluted in 2018. Scientists had analysed the water and found some harmful matter in it. This was the result of an earthquake at the source of the river. Similarly, the garbage that we dump into rivers pollutes the water, making it unfit for all living beings. Other sources of water pollution are industrial waste and the wastes from commercial establishments. Industries release waste material into the rivers.and make them toxic.

Our soil can also become polluted when the fertiliity of the soil is lost and it becomes unfit for human and animals use. Use of too many pesticides, dumping of non degradable household and industrial waste can also damage the soil. Such practices need to be stopped. Only then will the world be a safer place to live in. People should be aware of the danger posed by pollution to the survival of life on Earth. Together, we must do all we can to save our planet and ourselves.
