Hello teacher. My name is.....Now I will tell you about my topic: why is water polluted and some solutions to protect the water environment( seas, rivers, lakes, oceans...). First, we have to understand what is water pollution ? The water pollution is water pollution is the contamination of water bodies, usually as a result of human activities. Water bodies include for example lakes, rivers, oceans, aquifers and groundwater. Water pollution results when contaminants are introduced into the natural environment.  So what is the cause of water pollution? The first is industrial waste. Industries and industrial sites across the world are a major contributor to water pollution because of waste from industrial zones has been discharged directly into water sources such as: lake, rivers...The second is due to personal and household waste, sewage and wastewater from each household is released into the sea, it cause of health-related issues in humans and animals alike. Addition,  it is also due to global warming, oil leaks, chemical pesticides from agriculture....and the main cause is human consciousness. Therefore, we need to have measures to protect water sources such as; raise people's awareness, do not throw garbage into water sources, prevent oil leaks, handle industrial waste properly, do not use chemical pesticides, participate in cleaning activities in canals, rivers, ponds ...Let's join hands to protect water resources because they are extremely important to our life! That all. Thank for your listening!
