Currently, there are two topics to which we refer very frequently: Global Warming and the importance of recycling. It is true that these topics are of great transcendence for the environment, since they invite us to improve the living conditions of human beings and, thus, safeguard the “destiny” of future generations; However, we must not forget that the care and saving of water is essential for the survival of life on the planet; for this, here we provide some meaningful and alarming data about the water conditions on the earth (in order to create environmental awareness) and, in addition, several tips on how to save water and how to avoid contamination.
Water presents an essential contradiction since it is considered the most abundant element on the planet. However, it is the most scarce. This is because only 2% of the planet’s water is consumable (freshwater) and, this amount is not evenly distributed in the world but is concentrated in few areas of the earth such as the temperate zones and the humid tropics. For this reason, fresh water is scarce in many regions, such as the Middle East, Africa, certain parts of Mexico, the United States and Latin America.
It is essential to understand that as the population increases, the use of water intensifies, therefore, the more pool we demand, the more easily it will be exhausted. The industrialized countries are those that require a more significant amount of water. However, water consumption by each person is very low, since the actual use of water is divided as follows: 69% goes to agriculture (especially for the irrigation of crops), 23% uses the industry and 8% is for domestic use. However, one of the causes of the scarcity of water is the waste of it; For example, an average US citizen uses 70 times more water in his home than a citizen of Ghana.
The most significant issues we face concerning water is its pollution, an act that is caused by different human activities. Over the years, human beings have used water sources (rivers, lakes, and seas) as garbage dumps; we have thrown in oils, organic and inorganic waste, heavy metals (mercury and lead), detergents, petroleum, fertilizers, pesticides, radioactive materials … the list is endless. In summary, a large percentage of the water (sweet and salt) on the planet is contaminated, so much so that 20% of all aquatic species are extinct or in danger of disappearing.…
