Answer 1

Pollution is when something is added to the environment that is harmful or poisonous to living things. Smoke or Dust in the air is a type of pollution as it is bad for the lungs when we breath in. Sewage in Drinking water is another type of pollution, as it can make people ill because it contains germs and bacteria. People living next to a building site where there is too much noise can become sick as they cannot sleep.

As pollution grows, ways to combat it have grown too. Solar energy and wind energy give people other ways to power their homes. When people use these alternative forms of energy, they put less carbon dioxide into the environment. It is so harmful for living things.

There are types of pollution:

1. Air pollution- Air pollution is caused by poisonous gases, sulphur dioxide, nitrogen dioxide, carbon monoxide and very small particulates. It is also caused by factory smoke and harmful gases released by the fires that makes vehicles and factories go.
It is also caused by crackers. It may causes breathing problems such as asthma. It also causes diseases like cancer. It causes global warming and acidic rain.

2. Water pollution- Water pollution is the presence of harmful materials in water, such as sewage, dissolved metals, waste from farms, factories and crude oil spilled from oil tankers. The three main substances that pollute water are nitrates from fertilizers, sewage and detergents.

Activities such as bathing and washing clothes near lakes, ponds or rivers add nutrients like nitrogen and phosphorous into the water bodies.This leads to excessive growth of algae on the surface of water. It blocks the penetration of sunlight and air, thus reducing oxygen.

3. Noise pollution- Noise pollution also known as sound pollution which is harmful to the brain and hearing of all animals and humans. This includes the sound of vehicles, loud speakers, airplanes, jets, train horns etc. Noise pollution can cause ear problems or even permanent deafness, especially to older people. It causes brain related problems too.

4. Land pollution- Land pollution is also known as soil pollution.  is caused when man-made chemicals, such as hydrocarbons, heavy metals, solvents, get into the soil. These chemicals come from industrial activities and from bad waste disposal. Soil pollution may cause health risks. The chemicals can produce harmful vapors, or they can contaminate water supplies underneath the polluted soil.
