Answer:
Explanation:
There are many causes of water pollution
1. Industrial Waste
Industries and industrial sites across the world are a major contributor to water pollution. Many industrial sites produce waste in the form of toxic chemicals and pollutants, and though regulated, some still do not have proper waste management systems in place.
2. Marine Dumping
The process of marine dumping is exactly what it sounds like, dumping garbage into the waters of the ocean. It might seem crazy, but household garbage is still collected and dumped into oceans by many countries across the world
3. Sewage and Wastewater
Harmful chemicals, bacteria and pathogens can be found in sewage and wastewater even when it’s been treated. Sewage and wastewater from each household is released into the sea with fresh water
4. Agriculture
In order to protect their crops from bacteria and insects, farmers often use chemicals and pesticides. When these substances seep into the groundwater, they can harm animals, plants and humans.
5. Global Warming
Rising temperatures due to global warming are a major concern in terms of water pollution. Global warming causes water temperatures to rise, which can kill water-dwelling animals. When large die-offs occur, it further pollutes the water supply, exacerbating the issue.
