Water pollution



River polluted by chemicals

Introduction

Fundamental to life on our planet, water has become a concern in all parts of the world. Irrational use and pollution of rivers, oceans, seas and lakes may soon lead to a lack of fresh water if there is no drastic change in the way humans use and treat this natural good.

Main causes and consequences of water pollution

The main factors of deterioration of rivers, seas, lakes and oceans are: pollution and contamination by chemicals and sewage. Since the Industrial Revolution (second half of the eighteenth century) man has caused all this damage to nature through waste, sewage, industrial chemical waste and uncontrolled mining.

Due to these problems, environmentally conscious governments have motivated the rational exploitation of aquifers (large underground freshwater reserves). In South America, we have the Guarani Aquifer, one of the largest in the world and still little used. Much of the water in this aquifer is located in the Brazilian subsoil (southern region).

Surveys by the World Water Commission and other international environmental agencies say that about three billion people on our planet are living without the minimum necessary sanitary conditions. About one million do not have access to drinking water. As a result of these serious problems, several epidemics of diseases such as diarrhea, leptospirosis, schistosomiasis, hepatitis and typhoid spread, which kill more than 5 million people a year, with more patients burdening hospitals and health posts of these countries.

Search for solutions

In order to find solutions to Earth's water resources problems, the 8th World Water Forum was held in Japan on March 18-23, 2018. Politicians, researchers and authorities from various countries have approved various documents aimed at taking action to solve the world's water problems. These documents reaffirm that freshwater is extremely important for people's lives and health and argues that, in order for it not to fail in the 21st century, some challenges must be urgently overcome: meeting the basic needs of the population, ensuring supply protection of ecosystems and springs, risk management, water valorization, division and efficient management of the planet's water resources.

Although many solutions are sought at governmental spheres and at world congresses, every day everyone can collaborate so that fresh water is not lacking in future. The preservation, economy and rational use of water must be present in the daily attitudes of each citizen. The conscientious person must save because the waste of fresh water can have dangerous consequences in the not too distant future.

- Products that most pollute rivers, lakes and seas: detergents, cooking oils, car oils, gasoline, industrial chemicals, paints, heavy metals (lead, zinc, aluminum and mercury).
