Answer 1

Good morning to all. I … studying in class … standard would like to speech on pollution at this occasion. My dear friends, pollution has been one of the biggest challenges affecting the environment and human lives. It is an environmental issue faced by people all across the world today. Variety of hazardous and toxic substances from different sources are getting intermingled into the environment and causing various types of pollution such as water, air, soil or land, noise, and thermal pollution. Smokes and toxic dust from the industries and factories get mixed to the air and causes air pollution. Such polluted air is very bad for the lungs when we breathed air in. Sewage and other wastes from the industries and factories have their ways directly to the large water bodies (river, lakes, seas, etc) and they get mixed properly to the drinking water causes water pollution. Such polluted water (containing germs, bacteria, toxic substances, viruses, etc) is very bad to the health of human beings, animals and plants (whoever drinks this water).

Now-a-days, environment is not peaceful because of the increasing noise level through the transport, sound systems, electronic devices, etc. Such voices are causing noise pollution and very bad to the natural stamina of our ears. Excess and unbearable noise of vehicles, loud speakers, etc can cause ear problems and even permanent deafness especially in older people and kids.

Man-made chemicals from the industries and factories such as hydrocarbons, solvents, heavy metals, etc get mixed into the soil when people use herbicides, pesticides, fertilizers, etc or through the spill or underground leakage of the chemicals. Such contaminants in the form of solid, liquid or gas are causing soil or land pollution which is contaminating the whole earth. Such contaminants are also causing water and air pollution as they get mixed to the underneath water supplies and some chemicals produce harmful vapors respectively.

Ever increasing the use of plastic by the people is causing huge level environmental pollution and adversely affecting the wildlife, wildlife habitat, and humans. Thermal pollution is increasing because of the huge level usage of water as a coolant by the power plants and industrial manufacturers. It is causing the change in temperature of water in the large water bodies. It is very harmful to the aquatic animals and plants as raised temperature of water decreases the oxygen level of water.

My dear friends, we have been surrounded by the thick cover of the pollution from all around means upside, downside, and both sides. We are living in pollution but the most surprising thing is that some people even do not aware of it. Big and developed countries are highly responsible to this increased level of pollution all around the world. This is the very challenging issue of this planet which needs to be solved on urgent basis. It cannot be solved by the effort one or two countries, however; it can only be solved if all the countries do hard and strict effort from various aspects regarding this issue.
