Class 3 English Lesson 5 Activity-10
Let's make a list of the major causes of water pollution.
Causes of Water Pollution
Agricultural activities: The use of pesticides, fertilizers and animal waste from agricultural activities can pollute waterways with chemicals and nutrients, leading to eutrophication and harmful algal blooms.
Industrial activities: Many industries discharge pollutants into waterways, including chemicals, heavy metals, and oil, leading to contamination of water sources.
Sewage and wastewater: Wastewater from homes, businesses, and industries contains a variety of pollutants, including pathogens, chemicals, and pharmaceuticals, that can contaminate water sources.
Oil spills: Accidental or deliberate release of oil into waterways can have devastating effects on aquatic ecosystems and cause long-term damage.
Landfills and solid waste disposal: Improper disposal of waste can lead to leachate contamination of groundwater, which can ultimately affect surface water sources.
Atmospheric deposition: Air pollution can be deposited in waterways through precipitation, leading to acidification and other negative impacts on aquatic ecosystems.
Construction activities: Construction activities can lead to sedimentation, erosion, and runoff, which can pollute nearby waterways with sediment and other pollutants.
Mining activities: Mining can contaminate water sources with heavy metals and chemicals used in the mining process, leading to long-term environmental damage.
Climate change: Climate change can exacerbate water pollution by altering rainfall patterns, increasing the frequency and intensity of storms, and causing sea level rise, which can lead to increased flooding and erosion.
