Question

speech on the topic " pollution a hazard".

Answer 1

Pollution is basically contamination. All of us have heard about this from our early school days, but the problem does become more obvious and more complicated as we delve into it. We do know that there are many effects of pollution and they are all harmful, but the extent to which we know about the effects of pollution has changed quite a bit.

Types of Pollution and health hazards

There are many different kinds of pollution and all of them have different effects on the environment and human health. Here is a brief introduction to the different kinds of pollution.

Air Pollution
Air pollution is the contamination of the air when harmful contaminants are released into the air. One of the biggest effects of air pollution is global warming. It also causes other problems like acid rain, ozone layer depletion, etc. As a result of this, people are being exposed to more harmful UV rays that have increased the occurrence of cancer among people. In the long run, it can also make people get lung cancer, skin cancer etc.Some of the biggest causes of air pollution are cars, motorized vehicles, industries, etc.Water pollution
Water pollution is the contamination of water bodies, such as ponds, lakes, rivers, oceans. Some of the biggest causes of water pollution are industrial effluents and people recklessly dumping waste in the water bodies. Water pollution can lead to loss of water resources for humans and it can also cause depletion of water life.Related ArticlesAir pollution can affect child's brain development: ExpertsDelhi continues to top world's most polluted megacities list: WHOPollution of water bodies deprive people of drinking water facilities. This is the reason why of all the types of pollution, water pollution is the one that is most obviously felt. Another hidden effects of pollution of water is the fact that the contaminants in water can damage the water life thereby affecting the entire food chain.Light pollution
Light pollution is the pollution caused due to use of too much light, especially in urban areas. Light pollution is not something that seems like one of the types of pollution that would affect people, but that is not true. We have seen how animals do require the stars, the moon etc. for migrating and travelling during the night time.They also need the dark for hunting and also to sleep well. In fact, one of the most harmful effects of pollution is the fact that it affects human sleep patterns. Humans need the dark to sleep properly and rest completely. As long as there are lights around, the brain would not completely rest. As a result of this, people will fall prey to problems like restlessness, fatigue, headache etc. In the extreme levels, it can even become insomnia.Noise pollution
Noise pollution is one of the kinds of pollution caused mostly due to urbanization and industrialization. The diseases caused by pollution includes fatigue, irritation, insomnia etc. Noise pollution can cause all of the above. In fact, it is a well known cause for migraines. It can also cause loss of hearing at a really young age for a lot of people. Noise pollution, since it renders people incapable of sleeping and resting completely, can also cause insomnia in the long run, which would have a lot of health repercussions as well.Soil Pollution
Soil pollution is contamination of the soil that is caused due to over dumping, over utilization of soil and excess chemicals being injected into the soil. Poor disposal systems, excessive use of fertilizers and pesticides in agriculture, etc. cause soil pollution, especially in agricultural areas. The plants would absorb all the harmful chemicals from the soil, thereby spoiling or even poisoning the person’s food. Groundwater sources can also become contaminated due to soil pollution, which would cause water shortage problems as well.

There are many other forms of pollution that have also proven to be harmful for human health, such as thermal pollution (which is the pollution that causes the temperature level to rise in the country).

In order to battle pollution, it is essential for people to know more about it for they will be able to fight against pollution only if they are aware of what the types are and what the repercussions of not controlling pollution will be.
