Human Caused Water Pollution and Its Environmental Consequences

By Sultan Dimas Erdhiarto (1209624110)

Water pollution has become one of the most serious environmental problems the world needs to face today, and its causes are deeply rooted in human activity. A major contributor to water pollution is industrial waste, which often contains harmful chemicals. A lot of the time, factories dump these substances into rivers, which lead to the oceans. These can contaminate drinking water sources, which can affect daily human life. Agricultural runoff is also another major cause for water pollution, when farmers use chemical fertilizers and pesticides, rainwater can wash off and carry these chemicals into nearby streams of water. Additionally, drinking water pollution can happen via the pipes themselves if the water is not properly treated, which leads to contamination. The effects of water pollution can cause algae bloom in the marine environment, which can create dead zones or low oxygen areas known as eutrophication. This causes plants and animals to suffocate. In certain cases, these harmful algae blooms can also produce neurotoxins that affect wildlife, from whales to sea turtles. Algae blooms can also cause health and economic effects for human, causing rashes and other diseases, while eroding tourism revenue for popular lake destinations due to their unpleasant looks and odors.

Understanding the difference between Online and Offline learning

Image
By Sultan Dimas Erdhiarto (1209624110) Learning in an online class often feels different from learning face-to-face. While both methods aim to educate students, they differ in several key aspects such as flexibility, structure, and engagement. Online learning is usually more flexible, allowing students to access materials and complete assignments anytime and anywhere. In contrast, face-to-face learning typically follows a fixed schedule and requires physical attendance. Student engagement also varies between the two. In face-to-face settings, teachers can directly monitor students and encourage participation through live discussions. On the other hand, online learning can make it harder for students to stay focused, especially when there is a lack of interaction or timely feedback. In conclusion, although both learning methods share the same goal, their differences in delivery and experience make each one unique.

Climate Change

Image
By Sultan Dimas Erdhiarto (1209624110) and Ferziandra Divananda Kartono (1209624112) Climate change is a growing problem that is largely affected by human activities. One major cause of climate change is deforestation, where trees that should help us maintain the climate by reducing carbon dioxide in the air are cut down. This can lead to some animals losing their habitat, extreme weather events, rising average temperatures, and rising sea levels. Another major contributor to climate change is the excessive use of electricity, which is mostly produced by burning fossil fuels. This process can release a large amount of carbon emissions into the air, further accelerating climate change. One possible solution to this problem is to start saving electricity. If we started using less electricity, fewer fossil fuels would be burned in the process. How can we use less electricity? The simplest thing is to turn off the electric devices when its not being used. Another way to reduce carbon emiss...
