Caring for the environment does not understand political color or social classes or rich or poor countries because it affects us all, something that many political leaders and businessmen refuse to understand.
We are often paralyzed by the question: what can we do to help the planet in relation to environmental problems? The answer is not easy. Every time we wear down the planet without giving it time to recover. What we spend in a year on impacts to nature, it takes the Earth at least one year and six months to recover.
The pollution of rivers is an older problem than the environmental one, but with the increase in the population on the banks of the rivers in cities, the volume of organic waste, sewage and chemical waste increased in such a way that the Waters are affected in such a way that their composition affects human beings who drink it as well as fauna and flora. Are we aware of the importance of water in the world and of the importance of biodiversity? Are we aware that millions of people lack access to clean water? Are we aware of how many millions of people die each year, mainly children, from diseases caused by unsafe water?
Water problems center on both quality and quantity. The community must know the importance of its quality and take charge of its care and preservation.
For this reason, fighting against the pollution of rivers is of vital importance.
Deserving the river means knowing how to make use of it and wishing that it never ceases to be of benefit to people. Deserving the river means respecting the rules, adopting an attitude that contributes to improving its conditions.
One way to reduce the effects of water pollution would be to use and create artificial wetlands because, basically, they are areas built by man in which the physical, chemical and biological processes of elimination of pollutants that normally occur are reproduced in a controlled manner. in them.
They have advantages over alternative treatment systems, because they require little or no energy to function. If enough cheap land is available near the aquaculture wetland facility, it can be a cost-effective alternative. They provide habitat for wildlife, being aesthetically pleasing to the eye.
At present, in many towns, treatment plants no longer meet their objectives due to old or increased pollution, due to industrial activity. Building new treatment plants for existing remote plants would imply a high cost; Connecting ancient plants with constructed wetlands can be an economically and ecologically acceptable alternative.
