Water Lover
Good Morning Dear world. We face an urgent water crisis, so we need to find an immediate solution. To combat the situation in this hot climate, we will all have to work together. It is also my intention to make everybody realize how much water is important to us that we need to avoid misusing it, especially children. Water is without a doubt an “Elixir of Life”. Don’t you think so? As the name implies, elixirs are magical liquids that can cure illness and give people immortal youth. Water is the basis of life and life cannot exist without it. pH of water is neutral, which makes it an ideal trilogical solvent. A pure drop of water is colorless, odorless, and tasteless. Among the many causes of water pollution are industrial pollution, domestic pollution, chemical pollution, biological pollution, etc. Water pollution is the result of physical or chemical changes in its properties that negatively impact human health, as well as the health of other organisms. Presently, water pollution is a major concern worldwide. Different countries and regions have varying levels of pollution. Several epidemics are linked to contaminated water in developing countries.
Water pollution can be classified by its type or source of contamination, such as:
Bacterial Pollution
Nutrient Pollution
Pesticide Pollution
Metallic Pollution
Thermal Pollution
Viral Pollution
Radioactive Pollution
Petrochemical Pollution
Natural or manmade activities can pollute water.
We can thus overcome water pollution by recognizing and controlling the causes that lead to water pollution.
My speech will end here and we will continue with it ? at the next meeting. Will come up again with same pictures!
Surface water pollution- Surface waters are the natural water resources of the Earth.
