FAQs on Water Pollution: Harmful Effects & Causes Video Lecture - Biology for JAMB
| 1. What are the harmful effects of water pollution? |  |
Ans. Water pollution can have various harmful effects on the environment and human health. Some of the major consequences include the contamination of drinking water sources, leading to waterborne diseases such as cholera and dysentery. It can also harm aquatic life, disrupting ecosystems and reducing biodiversity. Additionally, water pollution can contaminate food sources, leading to health issues when consumed by humans.
| 2. What are the main causes of water pollution? | |
Ans. Water pollution is primarily caused by human activities such as industrial waste discharge, improper sewage treatment, agricultural runoff, and oil spills. Industrial activities release toxic chemicals and heavy metals into water bodies, while untreated sewage and agricultural runoff introduce excess nutrients, pesticides, and fertilizers. Oil spills, mainly from transportation and offshore drilling, can have devastating effects on aquatic ecosystems.
| 3. How does water pollution affect aquatic life? | |
Ans. Water pollution can have severe impacts on aquatic life. The presence of pollutants in water bodies can deplete oxygen levels, leading to hypoxia, which can suffocate and kill fish and other aquatic organisms. Pollutants can also interfere with the reproductive systems of aquatic species, leading to reduced populations and even extinction. Additionally, certain chemicals and heavy metals can accumulate in the tissues of aquatic organisms, causing long-term health problems.
| 4. How does water pollution affect human health? | |
Ans. Water pollution poses significant risks to human health. Consuming contaminated water can lead to various waterborne diseases, such as gastroenteritis, hepatitis, and typhoid fever. Exposure to pollutants in water can also cause skin irritation, respiratory problems, and even certain types of cancer. Additionally, consuming seafood contaminated with toxins from polluted water can lead to poisoning and other health complications.
| 5. What can be done to prevent water pollution? | |
Ans. Preventing water pollution requires collective efforts from individuals, industries, and governments. Some effective measures include implementing proper waste management systems, treating sewage before releasing it into water bodies, reducing the use of pesticides and fertilizers in agriculture, and promoting sustainable industrial practices. Additionally, creating awareness about the importance of water conservation and supporting initiatives for clean water infrastructure can contribute to preventing water pollution.
