PREVENTION OF WATER POLLUTION

 What Can You Do to Prevent Water Pollution?



PREVENTION OF WATER POLLUTION

Half of the world's inhabitants will live in water-scarce areas by 2025, so every drop of polluted water today is an irreparable loss for tomorrow. That's why we must prevent water pollution with measures like the following:

  • Reduce CO2 emissions to prevent global warming and acidification of the oceans.
  • Reduce the use of chemical pesticides and nutrients on crops.
  • Reduce and safely treat waste water so that, as well as not polluting, it can be reused for irrigation and energy production.
  • Restrict the use of single-use plastics that end up floating in rivers, lakes and oceans, many as microplastics.
  • Encourage sustainable fishing to ensure the survival of species and avoid depletion of the seas.

What is water pullution and What are the causes

WHAT IS WATER POLLUTION The World Health Organisation (WHO) says that polluted water is water whose composition has been changed to the extent that it is unusable. In other words, it is toxic water that cannot be drunk or used for essential purposes like agriculture, and which also causes diseases like diarrhoea, cholera, dysentery, typhoid and poliomyelitis that kill more than 500,000 people worldwide every year. The main water pollutants include bacteria, viruses, parasites, fertilisers, pesticides, pharmaceutical products, nitrates, phosphates, plastics, faecal waste and even radioactive substances. These substances do not always change the colour of the water, meaning that they are often invisible pollutants. That's why small amounts of water and aquatic organisms are tested to determine water quality.
