Environment is nothing but our immediate surrounding. It is also defined as the physical and biological factors along with their chemical interactions that affect an organism.

If parts of the environment, like air and water, or soil become polluted, it can lead to health problems. For example, asthma attacks can result from pollutants and other chemicals in the air and in the home.

Presence of radon in soil is also a risk but it’s natural. But the environment is mainly affected by human activities, like lead poisoning from paint, or exposure to asbestos or mercury from mining or industrial use. We cannot change the natural risks but we should try to reduce the risks generated by us.

Major factors that affect the environmental health are air pollution, water pollution.

Air Pollution

Mixture of solid particles and gases in the air is nothing but air pollution. Emission of carbon -di- oxide from car and factories causes pollution. Dust particles and pollen spores present in the environment can cause air pollution. Ozone, a gas, is a major part of air pollution in cities. When ozone forms air pollution, it’s also called smog.

Some air pollutants are poisonous, they can create health problems. People with heart or lung disease, older adults and children are at greater risk from air pollution.

Air pollution isn’t just outside – the air inside buildings can also be polluted and affect your health.

Indoor Air Pollution

Air is omnipresent and if it gets polluted anywhere it can affect your health. Not only air outside your house or building or office but also the air inside should be clean.

Biological contaminants like mold and pollen, tobacco smoke, household products and pesticides, gases such as radon and carbon monoxide, materials used in the building such as asbestos, formaldehyde and lead also cause air pollution.

Sick building syndrome occurs when several people are affected, but no specific source of the illness is found. Indoor air quality problems usually only cause discomfort, and most people feel better as soon as they eliminate the source of the pollution.

We must try to keep our environment clean and healthy. This will only keep you and your family and society healthy.

Water Pollution

We all know that 70% of our earth and human body is made of water. We all need it. We need clean water to drink, to operate factories and recreations. Animals like fish and other marine animals survive on it.

Many different pollutants from industries can harm our rivers, streams, lakes and oceans. The three most common are soil, nutrients and bacteria. Nutrients, often from fertilizers, cause problems in lakes, ponds and reservoirs. Nitrogen and phosphorus make algae grow and can turn water green. Bacteria, often from sewage spills, can pollute fresh or salt water.

We must try to keep our environment as clean as possible to keep our planet safe.
