We understand water pollution as the alteration of its chemical properties, a direct or indirect product of human activities. Pollutants make the water unsuitable for human, animal consumption and even for recreational, industrial, agricultural and fishing use.
There are numerous polluting sources that affect rivers, seas and lakes and even rainwater, and that unbalance the biological cycles that take place inside them, causing extinctions, mutations, migrations and irreversible ecological damage that, in turn, convince other irreversible damage, which in turn leads to other secondary environmental damage. Even though there is a large number of initiatives to combat water pollution, these are insufficient to the daily injection of polluting elements that we submit to the planet.
Below are examples of pollutants that make their presence felt in the chemical balance of the waters, from the introduction of harmful substances that are difficult to eliminate by the ordinary biotic chains of the seas.
Agricultural substances and wastes
