The Importance of the Digestive System for Humans

The digestive system in the human body is important for breaking down substances like proteins, fats, carbohydrates, and converting food into energy for us. Clean, fresh water is a necessity for everyone and living/ non-living organisms because we need it to survive. Water pollution is ruining our lakes, streams, and more due to toxins and chemical waste being dumped in our waters. The United States of America is a developed country with many advancements on water filtration, whereas, South Africa is an underdeveloped country with lack of advancements in water filtering.

We need access to clean water for humans and living/ non-living organisms because, without it, it can cause health issues to our digestive system, waterborne diseases, and lack of advancements for filtration can cause problems for underdeveloped and developing countries.

Waterborne diseases are caused by organisms that are in contaminated waters or untreated waters and can affect the digestive system greatly. The most common types of waterborne illnesses are amoebic dysentery, cholera, and many more in the category.

A research table shows many waterborne diseases and its sources, outbreaks, and many more on the table (Kulinkina, Shinee, Herrador, Nygard, & Schmoll, 2016). One of the most well-known diseases is cholera, an illness in, which leads to death if not treated right away. Malaria is one of the deadliest killers among us in the world, almost 500 million people every year are infected. Mosquitoes transfer their blood into drinking water and parasites get in causing our water supply to be infected (Stirton, 2012). The bacterial disease is found in contaminated waters and is bad for the digestive system.

Virus particles get into our drinking water streams in many ways, but especially through domestic wastewaters from agriculture activities, sewers, and more (Committee Report, 1979). These are the reasons why a lot of viruses and parasites get into our water supply and infect it, making us sick or even worse, die. In the context, a study was formed for human subjects, especially children in their youth (Deen et al., 2016). The results came to the conclusion that children who were under the age of five were at the most threat (Deen et al., 2016). Children around a young age are more likely to get sick from this compared to an adult because they do not have the immunity build strong enough for this. Overall, we can find most of these diseases in contaminated waters due to no sanitation, and the bacteria in them can lead to death if drinking from the source to our digestive tracts; therefore, leading to how water pollution can affect wildlife and other beings in the world.

Water pollution is a huge problem for everyone, including wildlife and other beings that need it in order of survival. In the text, most industrial buildings produce waste, and it flows towards the lake and streams nearby where aquatic and other life is at, but now covered in a blanket of sludge (Mackenthun, 1970). The problem became worldwide when people have seen no fish in the waters and the taste of it is more awful rather than been refreshing (Tarzwell, 1965). Water pollution can cause devastating effects to wildlife, whether they drink it for survival or live in it. All life needs water for survival because most are made from water, so if drinking water supply and homes are contaminated it will be difficult to live (Hennigan, 1969).

Materials that contain toxins are a huge ordeal to aquatic life because it causes harm to the environment and the fish themselves (Mackenthun, 1970). Exposure to chemical waste to wild and aquatic life is serious due to causing a great deal of effect on the environment and themselves, the possibility of mutation (Water Pollution, 1952). Aquatic life being affected by pollution in their homes is murdering and water supply will decrease due to water turning into waste by the toxins from industrial buildings. Contaminated water that contains metals or toxic leaves an ordeal for the water community which fish, plants, and other organisms reside in a home to survive (Mackenthun, 1970). This shows that with all the chemical waste contaminating waters that we share with other life forms that reside in them, it is causing an epidemic in our home. Overall, water pollution is affecting everything from humans, aquatic life, wildlife, and our ecosystems, so we need to protect the waters for everyone to stay clean, so we can use them for drinking supply and help protect the environment from harm.

There are different countries that are either developed or still developing, and some of the advanced technology for water filtration some have and others do not. The United States of America is a country with advancements of many things, one being purified water, so we can drink it, however, South Africa is still developing and is not with us just yet. South Africa has had devastating water scarcity and its suppliers to help purify the drinking supply is limited due to lack of advancements in the country (Ashton, 2002). The people in South Africa have to wait long hours to receive a good amount of water in their wells or rivers, but most of the time the quality is terrible due to dust or ruined by animals (Thompson, 1933). The United States of America have filters to purify water and do not need to wait hours, unlike South Africa. Even though both the United States and South Africa go through the same process of getting water are similar, but the United States has the technology to purify the water for us to drink without worrying.

South Africa has to throw away the tainted water because of no water filtration system to help them. Women are mainly the ones that get drinking water for their families in Africa and use their own cloth as a way of filtration for receiving water. In the rural parts of Africa, a lot of people die due to living in remote parts, but especially with no access to fresh water (Stirton, 2012). The rural parts of Africa are harsh because it is the countryside away from towns, along with hard locating a water well with fresh drinking water. Dracunculiasis or Guinea worms are a common parasite among Africa in contaminated waters, and these worms like to live in water holes in the parts of Africa near streams and rivers (Stirton, 2012). In the text, while the developed countries are safe from harm’s way, the developing countries are still in trouble due to lack of technology to prevent such things like cholera, a bacterium that invades the body through contaminated water (Levy, 2005). Drinking unclean water leads to illness and possibly death if untreated, so developing countries like South Africa need help. So overall, there is a huge difference between both countries in one that is developed, and the other still developing, and one has the technology to purify water without worry, and the other continues to struggle because of no advancements, so South Africa is struggling to keep their water supply clean.

Overall to prevent water pollution, so we can save our ecosystem and environment from such damage, so we can still have a home to go to. The United States, a developed country, whereas South Africa, a developing country, both have differences and similarities, but the United States is safe from water pollution due to the technology it has to purify it. South Africa does not have any of the advancements the United States does, so it is difficult for them to clean the tainted water they have for their drinking supply.

In conclusion, We need access to clean water for our digestive systems, so we do not get sick from any water-borne diseases like cholera and dysentery, and prevent water pollution, so we can save our ecosystem and environment. Our bodies need water to survive along with other life forms because they need water for survival as much as we do. Industrial growth rises as lakes, streams, and more are polluted with sludge and affects drinking supply and aquatic life. Countries like South Africa do not have the technology the United States does, so purifying water along with chances of survival is difficult.
