Answer 2

Explanation:

Sources of pollution

If large amounts of fertilizers or farm waste drain into a river the concentration of nitrate and phosphate in the water increases considerably. Algae use these substances to grow and multiply rapidly turning the water green. This massive growth of algae, called eutrophication, leads to pollution.

The best way to clean the polluted water is not to clean the polluted water but to stop polluting.

• Use Less Plastic.

• Reuse Items.

• Recyclable Options.

• Do Not Dispose of Oils in the Sink.

• Cleaning Chemicals.

• Handle Toxic Chemicals Properly.

• Shop to Stop Water Pollution.

• Do Not Throw Away Medicines.
