Water pollution is a growing crisis in the world that affects everybody. All beings on the planet rely on water for their very survival. To be specific every being depends on water. Unfortunately, many sources of water have been affected by human activities and soil pollution from a wide variety of sources. Water pollution cause many problems to the health of the planet and its inhabitants. It has been estimated that over 40% of the rivers, lakes and streams in the United States are too polluted to swim in or fish in. When water pollution spreads, it can cause serious consequences.
This speech will be looking at the factors that cause pollution, and the effect that pollution has on our present world. It will also look into what it has in store for the future if things do not get better. It will also search for some of the methods used to treat and clean-up wastewater, and oil spills. At present, the industrialization of many countries is severely affecting lakes, streams, and rivers. If action is not taken to improve the situation, it is going to have some severe environmental problems in future. All diverse types of water pollution are contributing factors in this problem (Clescerl).
One very big cause of water pollution is large farms and feedlots. These facilities raise hundreds of thousands of pigs, cows, or chickens in a relatively small amount of space. The resulting sludge and manure that is emitted from these animals creates a mountain of toxic waste (Newton 102). Animal manure is known to be high in nitrates. Most large feedlots also treat their animals with artificial growth hormones and antibiotics, which are then also emitted into the soil and run off into the water supply. This results in a very contaminated area that causes major water and soil pollution. Another problem with these large feedlots is the amount of soil erosion that takes place because of not having any ground cover. The animals are typically housed in a slew of mud and manure (Schueler). With no ground cover to hold down the soil, the rain washes all of the contaminants right into the nearby water systems along with a lot of mud and sludge that further pollutes the water and causes a murky appearance. When water becomes too murky the sunlight cannot reach the plants on the bottom of the rivers and streams and they eventually die. When this happens, there is a decrease in oxygen in the water, which causes more plants to die. It is a viscous cycle that results in the death of many plants, animals, and aquatic organisms.
The Organic wastes that decompose in a body of water reduce the amount of oxygen found in it. The breathing matters in the lake need oxygen to survive. If the oxygen level is reduced to zero, all fish in the lake die. Any type of decomposition that does not have oxygen starts to produce toxic gases such as Hydrogen Sulphide. Pulp and paper mills and municipal sewage also causes Biochemical Oxygen Demand. Nutrients, mainly nitrogen and phosphorus, enrich waters and hasten the aging of lakes and streams. In addition, the result
of this is rich plant life, which proscribes recreational activities. Plankton blooms also depress oxygen levels as mentioned before and therefore, endangering living organisms (Selna 12).
One way that water and soil pollution can be prevented is by growing a buffer zone around farms and waterways. A buffer zone would act as a filter of sorts to filter out a lot of the sludge and chemicals that are drained into the water from the large feedlots. By growing a wide variety of ground cover as well, it will prevent the depletion and erosion of the soil, which will further protect the waterways from becoming polluted. Taking steps now to prevent water and soil pollution will help protect the water sources in the future.
Are we not aware of the different problems occurring in our nature, especially in different bodies of water? Water pollution is the cause of our undisciplined actions and irresponsibility. We, humans are only creating problems that consequently we will also carry the burden of these problems. We all know that water pollution can affect our health badly and seriously. It can cause such sicknesses and diseases that will badly affect our health. We all know how important water is. Water is compulsory to our body. Therefore, we should keep, protect, save, and help prevent our waters from being polluted, we should act as early as now, and we should save rivers, seas and oceans, and other bodies of water because we will also bear the burden of this problem. We should not wait for the time until people are competing just to get sufficient, fresh and clean water, the time where clean water is insufficient to the people and animals, and the time where in our sources of water are diminishing or until the time where there are totally no sources of water. Therefore, let us be disciplined and responsible enough to save, protect, and conserve not only sources of water but also our mother nature because our nature provides and helps us in our daily lives. Let us just realize how important our mother nature is. It is our only source of living. Let us not destroy it nor pollute it. Let us act for a change. We need and we should help save and conserve our mother nature, especially the different bodies of water. Absolutely, there are many simple ways in how we can help. Change ourselves before we construct changes in our nature. Act right now!
