Can You Allow Water Pollution to Go Unnoticed?

Water – a critical source of life. And when you begin to think about it, water pollution has long lasting effects on the marine ecosystems, wildlife health and even us humans.

Water covers approximately 70% of the earth’s surface and 60 % of the human body.

If you haven’t already started, it might be time to think more about water pollution, its causes, the effects and some preventive measures.

 

Sources of Water:

Water is available from many natural resources like waterfalls, the ocean, rivers and the sea which are all considered as surface water.

These sources of water are exposed to evaporation and seepage which provides another source of water known as groundwater.

 

Causes of Water Pollution:

Water is polluted for three main reasons:

  1. Industries
    Chemicals, waste and other unused solid materials are disposed through pipes or open canal into the water sources. The toxin released is a main cause of water pollution.
  2. Agriculture
    Today, most farmers are using fertilizer to grow their crops faster. Little do these farmers know that the fertilizers are not only damaging the water but also their health!
  3. Homes
    Daily waste of plastic bags and other household materials, are often disposed into the sewers. Often septic tanks are not installed properly and as a result of which the underground water supply becomes heavily polluted.

 

Effects of water pollution:

Water pollution is the sure-fire route to many diseases and often times have a fatal impact on humans, wildlife and the marine ecological systems.

Human being – As a result of water pollution, we are affected by the spreading of diseases like cholera, typhoid and other skin diseases. This can occur through consuming contaminated water.

Wildlife health – Wild animals depend on nature for water which comes from the sea and rain-fall. Should these resources become polluted, imagine the consequences on their health?

Marine ecological system – From tiny fishes to large sea-fishes, just the thought of swimming in filthy and contaminated water should be enough to drive home the message of water pollution.

 

It is our duty to keep the environment free from pollution since we are also the largest contributors to its pollution. The time has come for every single one of us to start changing some of the simple activities we do to help the environment.

Does Light Pollution Affect Us?

Artificial light is the source of illumination specifically at night, and is needed to:

  • Illuminate the streets and roads at night
  • Protect homes and businesses at night as a security measure
  • Provide us with a way to continue our activities after dark

But when is it considered too much?

Because as you’ll discover, light as good as it is can be a source of pollution when we are over exposed. After all these lights are artificial and can have damaging impact on both children and adults alike.

What is light pollution?

These artificial lights can also be described as polluted light, when it creates disturbance to people. It consists of several elements:

  • Light trespass
    When artificial lights trespasses into another person’s house through the window. While it is useful for you, it becomes a form of polluted light to them. In fact, once it crosses the boundary of the property on which the light is located, it can already be described as light pollution.
  • Glare
    Seen as an uncomfortable light becoming visible against a darker background.
  • Sky glow
    This polluted light can be seen miles around towns and cities as a result of a scattering of artificial light frp, airborne dusts and water droplets.
  • Security lights used in the multistoried buildings and their surroundings
  • Floodlights used to illuminate games spots and various entertainment programs
  • Street lights
  • Advertising lights

Sources of light pollution:

Effects of light pollution:

The most common impact is that it changes another person’s quality of life. For example, it might be disturbing someone else’s sleep pattern with a strong bright light that shines directly into their room at night.

A common effect on city areas, it becomes more difficult to appreciate nature when this artificial light reduces the natural brightness of the moon and the stars. In addition, there is the element of energy being wasted.

In countries like US, UK and even Singapore, huge quantities of fossil fuels are used to provide sufficient energy for lighting up the city.

Prolonged exposure to artificial light also affects our vision especially with poor management and control.

How can we reduce light pollution?

The easiest way to reduce the light pollution is to be aware of the energy wastage through unnecessary lighting in around our homes at night. For domestic uses, consider switching to energy saving light bulbs.

While light pollution might not have a direct harmful effect like water and some of the other types of pollutions, it can easily be controlled.

And we all have the power to turn off unwanted light and play a part in saving energy and resources.

Air Pollution – The Air You Breathe

Air is the principal source of life for humans, plants and just about every living thing. After all the phrase “living and breathing” comes together doesn’t it?

So when you consider the effect polluted air has, the consequences can be dire as it causes discomfort, diseases and even death at times. Air pollution can be a chemical, biological or physical agent that changes the atmospheric standard. So the question remains…

How does the air become so polluted?

Air pollution is cause through a substance in the air known as air pollutant. These pollutants are found in all three states of solid particles, liquid and gaseous form. In addition they may be natural or man-made particles.

Pollutants are also classified as primary or secondary types. The primary pollutants are directly produced within a process, such as ash from volcanic eruption, carbon monoxide from the motor vehicles exhaust and the sulphur dioxide released from factories.

 

These substances when mixed with the atmosphere, creates air pollution.

Effect on humans:

The polluted air causes damage health on humans by increasing various diseases like – cardiovascular system, cystic fibrosis, COPD, asthma and lung cancer to name a few.

It also damages our respiratory systems making it more difficult to breathe and affecting our day to day activities. And pregnant women are at a similar risk as the polluted air might cause serious developmental damage to the unborn child.

As per declaration of the World Health Organization, approximately 2.4 million people die each year from various types of diseases as a direct result of air pollution.

Effect on plants:

Plants are directly dependable on air and water. As such, polluted air interrupts the normal growth of plants. The crops which are consumed are not spared either. Their natural production rate takes a hit and release lesser oxygen into the air and disturbing the balance in many areas.

Impact on rivers and streams:

The polluted air increases the normal temperature of the water of rivers and streams causing acid rain-fall. This increase of temperature also damages the lives of the fishes and other living organisms.

Preventive measures to take:

Air-pollution today has become a global problem. Many preventive measures are being adopted throughout the world abiding by the direction of each respective authority figure. Industries and vehicles are commonly responsible for contributing to almost 60% of the world’s pollution.

Some preventive measures you can take on your own includes driving less, adopting eco-friendly driving practices, selection of air-friendly products and making use of fuel reformulators to save energy as much as possible and reduce waste.
