Topic: what about water? (Read 153 times)

Water pollution has become the most complex global problem.
Its long-term effects are far-reaching because it affects not only the environment but also human beings and animals.
Increasing drinking water pollution has become a global issue mostly due to a range of diseases, health problems and increasing human mortality.
Pollution is a change in water quality above the permissible limit values.
It is caused by the introduction, release and disposal of various substances, energy or other pathogens, which changes the useful properties of water and worsens the state of aquatic ecosystems.
These changes endanger human life and health and the state of the environment.
There are various causes of pollution.
The world’s main consumer of water is agriculture where chemicals are often used to protect crops from damage or disease.
This improves crop growth and the chemicals go into the groundwater from where they reach lakes, rivers or streams and pollute them.
Industry is also one of the main causes of pollution because it produces toxic waste that is filtered in water and becomes dangerous for the world of sea and land waters and man himself.
The formation of heavy metals in water has been linked to birth defects, cancer, and infertility and developmental problems in children.
In addition to humans, water pollution can also cause natural disasters such as storms, earthquakes, floods and volcanic eruptions.


From the world of medicine, dirty water is the first source of mortality in the world.
It is estimated that about 3.6 million people, mostly children, die each year from dirty water.
Dirty water causes dysentery which leads to even greater dehydration.
It happens that people die mostly because of consuming such water.
Half of the world's hospital beds are home to people suffering from diseases related to dirty water.
When we open the tap we have to remember that people (mostly women) in Africa and Asia walk an average of six kilometers to the water.
Perhaps this information warns us how valuable water is and how rationally we should consume it.


What do you think what can we do, as humans to reduce water pollution?
